Citrus sinensis

Citrus sinensis (L.) Osbeck, Reise Ostindien 250-251 250 1765.;
sweet orange;
Fruits & Vegetables Week: Citrus sinensis, Valencia orange: Citrus sinensis, Valencia orange. The Valencia or Murcia orange is one of the sweet oranges used for juice extraction. It is a late-season fruit, and therefore a popular variety when the navel oranges are out of season. For this reason, the orange was chosen to be the official mascot of the 1982 FIFA World Cup, which was held in Spain. The mascot was called "Naranjito" ("little orange"), and wore the colours of the Spanish football team uniform. 

upcoming Citrus week: I stumbled upon an old discussion string regarding Citrus in general and Mosambi in particular.
In the past few months I have made much progress towards my own "de-confusion" or clarification of mind.
I think that, as far as names are concerned, I can bring a little leadership in the coming Citrus week.
I would suggest first that whenever a name is mentioned, at the very least its original location should be mentioned, its corresponding name in script (as opposed to the ever misleading romanised version) should be given, and if possible the matching botanical name. I can provide much of what would be missing but we may wish to limit ourselves to short lists. At this point it is not helpful to check my MMPND pages on "Sorting Citrus names" but I will mention when a more reliable string of names is being posted on that site. I truely believe that our discussion group has the potential to sort most of the nomenclatural confusion in regards to Citrus. It may take more than a week though, especially if people send a lot of photos.
2 examples of resolved names in Bengali and Hindi:
মোসাম্বি (Mōsāmbi) -> Citrus × sinensis (L.) Osbeck 'Mosambi'
मौसम्बी Mausambee -> Citrus sinensis (L.) Osbeck (Navel Group) -> Citrus × sinensis (L.) Osbeck 'Mosambi'
This simply proves that one has to look further down than the generic level in order to clarify the vernacular, especially when dealing with cultivated food plants.
Rutaceae Week: Citrus sinensis "Malta" from Kausani: Citrus sinensis (L.) Osbeck, Reise Ostindien 250. 1765 
Common names: Sweet orange, tightskinned orange
This tight skinned orange which generally needs to be sliced instead of peeling and separating segments as in C. reticulata has numerous cultivars. This one photographed from Kausani is known as Malta.
Many thanks .., good to see the malta plant.
I had twice bought the fruits considering them to be orange.

Rutaceae Week: Botanical name of Mosambi:
Not able to resurface I am reviving the older thread through this link!searchin/indiantreepix/Mousambi/indiantreepix/W13Ft2_GnR4/F53ETzybKX8J
It is turning interesting. Traditionally Mosambi is supposed to be Citrus limetta
This according to The Plant List is a synonym of C. medica
GRIN accepts C. limetta as distinct species but names used are Sweet lime and sweet lemon, no Mosambi name is mentioned.
Useful Plants of India (CSIR) treats Mosambi as C. sinensis
I did reply to this question in details a while back but it may have got lost. I'll try to give as good an answer again.
First this is a cultivar of C. sinensis. As has been pointed out already several times by various people this week, the problems stem from the fact that most academics treat plants at a specific level, ignoring anything sub-specific sometimes, sub-variety nearly all the time. Due to the mixing of old names with the new, the name gets first attached to a species, then to another because it is a synonym or by mistake - yes experts make mistakes sometimes. When one goes back in time the origin may be a cultivar name as is the case here. Added to the botanical confusion is the linguistic confusion. Mosambi becomes Mausambee, Mōsāmbī, Mōzāmbi etc. then enter the scripted names মোসাম্বি, ಮೊಸಂಬಿ, मौसम्बी , मोसम्बी , मोसाम्बी , मोज़ाम्बि , मोसंबी etc. None of these is validated.
Depending on how these names were created they may be correct or not, correct in a language not in another but using the same script. In my mind the correct name for this cultivar is: Citrus × sinensis (L.) Osbeck 'Mosambi' Therefore matching it with simply the species Citrus × sinensis (L.) Osbeck is not completely wrong.
It may well be that the name Mosambi is applied to some other species in some parts of India but it has to be displayed next to the name in order to avoid perpetuating the confusion. I will leave this with you all to comment on and give you the picture as I see it now at the end of the week, Perhaps by then you will have changed my mind.

Rutaceae Week: Citrus sinensis "Valensia Orange" from California: Citrus sinensis (L.) Osbeck "Valensia Orange"
A popular orange in USA, also known as Murcia orange is commonly used for extracting juice and as table fruit. Photographed from California.
Valencia is the correct spelling. "Valensia" is found on the internet but is not correct.
Valencia is both a cultivar name and a group name. Citrus sinensis (L.) Osbeck is still valid, Citrus ×sinensis (L.) Osbeck is the new name after Mabberley's classification.
Citrus ×sinensis (L.) Osbeck 'Valencia'
Citrus ×sinensis (L.) Osbeck (Valencia Group) 'Dom João'
Jorma Koskinen, 2006 - 2011, Citrus Pages.

Good to have such fruiting trees at arm’s length in the garden.
Rutaceae Week: Citrus sinensis :Navel Orange" from California:   Citrus sinensis (L.) Osbeck "Navel Orange"
Such fruits have generally the growth of second fruit at apex which protrudes like a human navel. The skin peels off more easily than other members of this species, and are commonly used as table fruit, though less juicy.
Photographed from California.

Fruits bought from a fruit vendor, grown locally, on the 29th of October,11.
The size of our common Mosambi, outer cover very thin.
Fruits very juicy, sweet with a slight taste of lemon but not sour.
Any clues?

I think this is Lime, Kagaji neebu

I think yes Citrus aurantifolia
Thanks for the id but the taste is very sweet & fruit much bigger in size.
In that case consider Malta, Citrus sinensis, which is sweet, pulm whitish and rind thinner.

Rutaceae Week, follow-up, "Names of Plants in India", 1st instalment:  It is hard to choose where to start for there is not really a beginning and no end in sight. Chinese people have a saying "Every long journey starts with a tiny step".
So here is first what has been the big revelation for me. Hidden behind some links in one of Dinesh's postings was what some of you had proposed / wished for and that I was also waiting for. The initial building of an amazing database called "Names of Plants in India". It does not display the basic info for such a site so a review cannot yet be written about it. I have written one nevertheless that will appear online when I have all the details. It is however fully operational and can be used. I warmly invite you to consult it ... and yes it has got photos! The URL is < >.
Now just a couple of entries calling for further feedback from you all.
We all know that the name "Mosambi" is used for other taxa (plants). We will come back to it when we treat these species. I believe the following to be the original vernacular.
Citrus × sinensis (L.) Osbeck 'Mosambi'
BENGALI : মোসাম্বি (Mōsāmbi).
ENGLISH : Mosambi orange, Mosambique orange.
HINDI : मौसम्बी Mausambee, मोसम्बी Mōsambī , मोसाम्बी Mōsāmbī, मोज़ाम्बि Mōzāmbi

KANNADA : ಮೊಸಂಬಿ ಹಣ್ಣು Mosambi hannu ?
MARATHI : मोसंबी Mosambi.
TAMIL : சாத்துக்குடி Cāttukkuṭi ?
TELUGU : బత్తాయి పండు Battāyi paṇḍu.
"Fruit medium-large, slightly oblate to globose or broadly obovoid; areolar ring regularly shallow; moderately seedy. Color light yellow to pale orange at maturity. Rind medium-thick; surface moderately to roughly pebbled, and faintly striped with narrow, longitudinal grooves and ridges. Flesh color straw-yellow; somewhat firm, juicy; flavor insipid because of very low acidity. Early in maturity.
This very distinctive variety is of unknown origin, but the name, of which there are numerous spellings, suggests that it was taken from Mozambique, East Africa, to India, presumably by the Portuguese. The brown color of the chalazal spot indicates that it does not belong to the sugar orange group, as some have assumed, but that it is a low acid orange, the acidity of which is further reduced by the Indian climate and the rough lemon rootstock on which it is grown.
Mosambi is highly popular in central India and is probably the most important orange variety of that country. According to Gandhi (1956), it is grown principally in the Bombay Deccan where total plantings were reported to be about 20,000 acres."R. W. Hodgson in Chapter 4 of Horticultutal Varieties of Citrus.
What we need now is validation of those names - spelling... and a photo or two, and some clarification.
If this is the Batavian orange, Cattukkuti orange, Loose-jacket orange, Sylhet orange, can it be బత్తాయి Battāyi, బత్తాయి నరింమ్జాపండు (Battāyi narimmjāpaṇḍu) Battāyi nāriṃzapaṇḍu ? We know it is not sweet but is it bitter at all ? could it be called a mandarine ?
Citrus × sinensis (L.) Osbeck 'Malta'
ENGLISH : Malta orange.
HINDI : माल्टा Malta (mālṭā). -> correct spelling ?
It may be difficult to find all these names in dictionaries but there is enough expertise in the group to work out what is correct and to validate it.

One observation. In my view the English transliteration of சாத்துக்குடி is Saattukudi or Sāttukudi. Tamil speaking members in the group ( Dr. ..., Dr. ..., etc.) may please comment on my observation.
In Tamil, சis correctly pronounced 'cha', and ஸas 'sa'.
So, for சாத்துக்குடி, 'chattukkudi' is the correct spelling. For 'Sattukudi' it has to be written as 'ஸாத்துக்குடி' which is not the case here.
I have posted (new) the amended list of names for Mosambi, taking into account all the answers in this posting. Please do not be offended when I say that there is no right or wrong answer. Some transcriptions are absolutely more correct than all the others. In this case Chattukkudi is IT. However, as we keep all old and invalid botanical synonyms matched to the correct preferred botanical name for ref. purposes and for tracking down errors made in the past, we have to do a similar thing with vernacular names. If anyone has to be blamed it is the authors who have been using transcriptions only and all the foreigners who have taken these as gospel and not always copied those names correctly. Modern devices such as converters / transliterators can help greatly in recovering scripted names but they can also confused the issues because they do not use the same standards of transliteration. Hence the need for us all to sort all these names. Sorry for the long explanation.

Rutaceae Week, follow-up, "Names of Plants in India", 2d instalment:   Thank you to our expert Tamil speakers. We are progressing a little. So below is the amended list of names for the Mosambi cultivar.
In this applied linguistics one cannot say that a transliteration is wrong or correct. It depends on how a word is arrived at, be it in scripted form of romanized form. However in some cases one match is definitely better than most. This is the case here. I display the not so good transcriptions because they are found in many publications. When one does a computer search one can miss a good name if it has only been searched in 2 or 3 of its less correct forms and the compiler has only posted the correct transcription. With this method one covers (hopefully) all possibilities. The preferred, correct, transcription is in bold so that the reader is in no doubt. In parenthesis are the alternate, less correct transcriptions.
Citrus × sinensis (L.) Osbeck 'Mosambi'
BENGALI : মোসাম্বি (Mōsāmbi).
ENGLISH : Mosambi orange, Mosambique orange.
HINDI : मौसम्बी Mausambee, मोसम्बी Mōsambī , मोसाम्बी Mōsāmbī, मोज़ाम्बि Mōzāmbi

KANNADA : ಮೊಸಂಬಿ ಹಣ್ಣು Mosambi hannu ?
MARATHI : मोसंबी Mosambi.
TAMIL : சாத்துக்குடி Chattukkudi (Cāttukkuṭi , Saattukudi, Sāttukudi).
TELUGU : బత్తాయి పండు Battāyi paṇḍu.
Could we found an Assamese name and a Gujarati name?

It looks like Citrus maxima
Thanks ...To me it doesn't look Citrus maxima; can be Citrus sinensis.

Citrus leaf is not very clear. it is difficult to say which var. without having a clear photo of leaf.
Yes C. sinensis is more likely. Fruit shape and much narrower petiole wings suggest that.,Delhi-DSCN5086.JPG?part=0.2&view=1&vt=ANaJVrFzyYmNHFt2RRt5QQdyWLRgnQbPhAuR34yI9QUcbpWfXjOSnyw_hHHH4B8OM2KRdav3nJzVyO6tC-zsscC8P5RE-QcQ0XGDa6W2dxBfboO--XJjw6s,Delhi-DSCN5085.JPG?part=0.1&view=1&vt=ANaJVrGm9fWsveh2koFkiyq6X1JSYW1Arxb4JwZWq-dUp0mu0cD2EOZYfQ5-jTBOdfgz7wiLw-UVjoVsFKRq6T_CgzVBsaMUWG7zUASsl_DuTZ3HVCuWM34

Citrus fruits seen at the Garden of Five Senses, Delhi on 6/12/2012.
A small, cultivated tree.
I think it is Chakotar Citrus maxima.

Citrus maxima/ grandis usually have broadly winged petioles.
Citrus sinensis I hope
Thanks for the id and corrections.
Saw your recent post on Citrus.
This would be Citrus sinensis only as suggested by you earlier?
Can you please validate?
I think yes, looking at leaves.
Thanks for the prompt reply. I take this as Citrus sinensis.
Scientific names of Citrus spp.. (mixed thread): 11 posts by 3 authors. 2 correct images as above.
i have a confusion regarding names of some Citrus species. many sites and Wikipedia says Scientifc name of Musambi is Citrus limetta but according to eflora of Pakistan its a cultivar of Citrus sinensis Taxon Page. We also call malta as Citrus sinensis. What is the accurate scientific name for musambi? Thankyou
there are other species. kindly mention if i am wrong for some citrus species
1. Kinnow/santra is Cirtus reticulata
2. khatta/khatti is Citrus aurantium (Bitter orange)
3. Meetha is Citrus aurantifolia
4. Gulgul is Citrus medica
5. Chakotra is Citrus maxima
6. Malta is Citrus sinensis
7. Narangi is Citrus microcarpa (its fruit size is small 2-3 cm and used mostly as ornamental)
Thankyou for your consideration
1. Yes Santra is C. reticulata, but Kinnow is a hybrid of  'King' (Citrus nobilis) × 'Willow Leaf' (Citrus × deliciosa) and be correctly be written as Citrus nobilis x Citrus deliciosa, sometimes cited as C. reticulata, but this does not sound good especially when both parents are well recognised species, it can't be placed under third C. reticulata
2. Khatta/Khatti should be C. jhambiri also placed as Citrus sinensis subsp. jambhiri (Lush.) Engl.
Citrus aurantium subsp. jambhiri Engl., but now Citrus taitensis
3. C. aurantifolia I hope is Kagzi nimbu, Mitha or Meetha should be C. limetta, sometimes placed as  Citrus × limon (L.) Osbeck 'Limetta
4. Galgal is Citrus pseudolimon 
5. Chakotra is Citrus grandis (syn: Citrus maxima).
6. Malta is Citrus sinensis, yes
7. For Narangi and others please look for these posts

Thank you so much sir. i will share some photos and what is the scientific name for musambi?
Citrus limetta : 3 posts by 2 authors. Attachments (4)
Thank you Sir. These are some photos of Meetha and musambi here in my area.. the first four photos are of meetha ............ Thanks a lot for your guidance.
Mitha or Meetha should be C. limetta, sometimes placed as Citrus × limon (L.) Osbeck 'Limetta 

As per discussions at
Citrus sinensis, Dr. Porcher calls it as Citrus × sinensis (L.) Osbeck  'Mosambi

I think C. limetta is more widely used name

Fruits & Vegetables Week: Citrus sinensis, naval orangeCitrus sinensisnavel orange, also known as the Washington, Riverside, or Bahia navel. This seedless fruit was a result of mutation, the mutation causes the orange to develop a second orange at the base of the original fruit, opposite the stem, as a conjoined twin in a set of smaller segments embedded within the peel of the larger orange. From the outside, it looks similar to the human navel, hence its name. Being sterile and seedless, it can be propagated only by grafting it on other hardy varieties. Because the mutation left the fruit seedless, and therefore sterile, the only means available to cultivate more of this new variety is to graft cuttings onto other varieties of citrus tree. 
 Slight correction, it is Navel (not naval) orange
