Common name: Wood Sorrel, Broadleaf woodsorrel, Mexican oxalis • Hindi: खट् मिट्ठी Khatmitthi • Manipuri: Yensil • Nepali: चरी अमिलो Chari Amilo

Native to: tropical Americas; naturalized elsewhere

Local people (Coimbatore) use the leaf as medicinal herb.  
 
As per efi thread:
1. Leaflets obtriangular to broadly obtriangular, (20–)30–50 mm long, 1.5–2.5(–3) times wider than long; stems and leaves arising from a cluster of small sessile bulblets; capsules and seeds rarely formed; flowers semi-homostylous ........ Oxalis intermedia
1. Leaflets obcordate to obtriangular, 15–40 mm long, 1.1–2(–3) times wider than long; stems and leaves usually arising from a single bulb, rarely producing additional sessile bulblets; capsules and seeds often formed; flowers tristylous, rarely homostylous …… Oxalis latifolia
The stemless species (Oxalis intermedia) is distinct from O. latifolia in leaves arising from a cluster of small sessile bulblets, leaflets broadly obtriangular leaves with usually acute angles and flat upper edge, larger green leaflets 30-40 cm long, smaller purple flowers more in number.   
 
The species is distinct from Oxalis intermedia in leaves usually arising from a single bulb, leaflets smaller (15-40 mm long), less broader, mostly obcordate to obtriangular but with rounded and obtuse (and not acute) tips, a clearer notch and forming fruits more frequently

Flora of Chakrata: Oxalis dehradunensis from Mussoorie Chakrata Motor Marg:   Oxalis dehradunensis from Mussoorie Chakrata Motor Marg
Sorry for poor picture Quality. These pics were shot by my old Nikon coolpix
L15 Hotshot digital Camera

A few more good pics of same plant same area
Sir these are from my last years visit to Chakrata
While processing my photographs I discovered that this may not be Oxalis dehradunensis which has much larger light green spotted leaves and pinkish flowers, a plant uploaded by ...: https://indiantreepix.googlegroups.com/attach/d9627cc213e422b9/Oxalis...
This plant of yours may be Oxalis latifolia

I always wondered about the differences between the two. I always thought the colour spots as just a variation
I think we did find Oxalis dehradunensis in Chakrata near our rest house. It was not in flowering. It did not have dots as in ... plant, but the larger, flat light coloured leaflets were distinctive. I am uploading the same.
Now for a shock. The Plant list considers this as unresolved name. I thought of doing some research. According to IPNI record Raizada did not describe it as new species, he published it as new name in Duthie's Fl. Upper Gangetic Plain, etc. v, 37 (1976), nom. nov. and the replaced name in the record is shown as Oxalis intermedia A. Rich
(can some one locate the original book to find why he rejected O. intermedia A. Rich?). According to The Plant List O. intermedia A. Rich is a synonym of Oxalis latifolia.
So both... conclusion and mine don't seem to differ much, if finally O. dehradunensis turns out to be a synonym of O. latifolia.
Perhaps going through the description in Herbaceous Flora of Dehradun, and perhaps Flora of Indian Desert (where I think I saw this species described) or any recent Flora should help.
Yes Sir
I have that Supplement vol by Raizada
will upload two pages in minutes
here are pages
I have seen the paper now. So Oxalis intermedia A. Rich is surely the basis of O. dehradunensis and obviously both are synonyms of O. latifolia as per The Plant List. So both our plants belong to same species.
Further final discussions as at  efi thread:
Raizada's new name (Nom nova) O. dehradunensis for O. intermedia A. Rich was based on early entry in IPNI considering 1845 (1842) as its date of publication as against 1841 for O. intermedia Steud., 1841. As it appears the date of publication of A. Rich. 1841 and opposite to what Raizada considered, Biophytum intermedium, 1839 antedates the binomial given by Steudal and is correctly Biophytum intermedium Wight, 1839 and not (Steud.) Wight, and citation for Oxalis intermedia is accordingly (Wight) Steud. and not O. intermedia Steud.
Recent studies have shown that Oxalis intermedia A. Rich. and O. latifolia are two distinct species, and not synonyms. This is supported by recent publications such as CONABIO. 2009. Catálogo taxonómico de especies de México. 1. In Capital Nat. México. CONABIO, Mexico City., Davidse, G., M. Sousa Sánchez, S. Knapp & F. Chiang Cabrera. (editores generales) 2013. Vitaceae a Geraniaceae. Fl. Mesoamer. 3(1): ined., and Nesom, G. L. 2009. TAXONOMIC NOTES ON ACAULESCENT OXALIS (OXALIDACEAE) IN THE UNITED STATES. Phytologia (December 2009) 91(3) 501-526.
I am sharing the pdf of last (2009) publication and reproducing below the key from the publication:
1. Leaflets obtriangular to broadly obtriangular, (20–)30–50 mm long, 1.5–2.5(–3) times wider than long; stems and leaves arising from a cluster of small sessile bulblets; capsules and seeds rarely formed; flowers semi-homostylous.........................................….Oxalis intermedia
1. Leaflets obcordate to obtriangular, 15–40 mm long, 1.1–2(–3) times wider than long; stems and leaves usually arising from a single bulb, rarely producing additional sessile bulblets; capsules and seeds often formed; flowers tristylous, rarely homostylous......…….Oxalis latifolia

I seem to have both these species in my collection, and would upload both.
Here is Oxalis intermedia A. Rich. from Chakrata and along Mussoorie Chakrata road.
Oxalis intermedia A. Rich., Hist. Phys. Cuba, Pl. Vasc. 315. 1841

This stemless species species is distinct from O. latifolia in leaves arising from a cluster of small sessile bulblets, leaflets broadly obtriangular leaves with usually acute angles and flat upper edge, larger green leaflets 30-40 cm long, smaller purple flowers more in number.

Today on seeing Oxalis intermedia, I was reminded of this picture.
Only one picture, that too not very clear.
Is it possible to id?
I think Oxalis latifolia, seems to have rounded lobea and upper edges.
yes it is

Oxalis dehradunensis
I don't know whether it is same as Oxalis latifolia.
Mahabaleshwar.

Oxalis intermedia
Please see discussion in the thread
Oxalis dehradunensis
This small herb was abundant in some areas of Panchgani. Maharashtra.
I think it is Oxalis dehradunensis (Dun Ambushi) according to Shrikant's book

Another plant for ID: This is a plant that I find growing as a weed in quite a few gardens. (mine including) Would be nice to know it's name and also any uses if it's there.
It seems to be some Oxalis species from Oxilidaceae
Closer to Oxalis dehradunensis (= O.richardiana).
It does look like O.dehradunensis. I wonder if it is edible?



Thanks ... for this interesting upload. The week, commencing on March 4, Monday should see interesting activity.
I was about to write to you when I saw your this mail.
Last year we had an interesting discussion which led us to conclude that Oxalis dehradunensis Raizada is a mere synym of O. latifolia Kunth.
As is clear from original publication of Raizada, he suggested this name as new name for O. intermedia A. Rich, 1845 (1842) (non Steud., 1841). According to The Plant List, O. intermedia A. Rich. is synonym of O. latifolia Kunth., and consequently O. dehradunensis should also be its synonym (although as with most other names The Plant List considers O. dehradunensis Raizada as unresolved name: I am going to write to them.
The Plant List conveniently ignores O. intermedia Steud., 1841 but it is listed in IPNI (Nomencl. Bot. [Steudel], ed. 2. ii. 240.). According to original publication of Raizada O. intermedia Steud. is a synonym of Biophytum intermedium (Steud.) Wight, but neither The original publication of Wight (I have checked the pdf of Wight's publication), nor FBI, nor The Plant List mention about (Steudel) Wight combination, nor the basionym. All just mention Biophytum intermedium Wight. Could you please throw light on this confusion.
Further final discussions as at efi thread:

 (4 images + pdf)  Last year we had detailed discussion on plants uploaded by ... and ..., ultimately concluding on the basis of listing in The Plant List, that it is a synonym of Oxalis latifolia Kunth, 1822
Raizada's new name (Nom nova) O. dehradunensis for O. intermedia A. Rich was based on early entry in IPNI considering 1845 (1842) as its date of publication as against 1841 for O. intermedia Steud., 1841. As it appears the date of publication of A. Rich. 1841 and opposite to what Raizada considered, Biophytum intermedium, 1839 antedates the binomial given by Steudal and is correctly Biophytum intermedium Wight, 1839 and not (Steud.) Wight, and citation for Oxalis intermedia is accordingly (Wight) Steud. and not O. intermedia Steud.
Recent studies have shown that Oxalis intermedia A. Rich. and O. latifolia are two distinct species, and not synonyms. This is supported by recent publications such as CONABIO. 2009. Catálogo taxonómico de especies de México. 1. In Capital Nat. México. CONABIO, Mexico City., Davidse, G., M. Sousa Sánchez, S. Knapp & F. Chiang Cabrera. (editores generales) 2013. Vitaceae a Geraniaceae. Fl. Mesoamer. 3(1): ined., and Nesom, G. L. 2009. TAXONOMIC NOTES ON ACAULESCENT OXALIS (OXALIDACEAE) IN THE UNITED STATES. Phytologia (December 2009) 91(3) 501-526.
I am sharing the pdf of last (2009) publication and reproducing below the key from the publication:
1. Leaflets obtriangular to broadly obtriangular, (20–)30–50 mm long, 1.5–2.5(–3) times wider than long;
stems and leaves arising from a cluster of small sessile bulblets; capsules and seeds rarely formed;
flowers semi-homostylous........................................................................….Oxalis intermedia
1. Leaflets obcordate to obtriangular, 15–40 mm long, 1.1–2(–3) times wider than long; stems and leaves
usually arising from a single bulb, rarely producing additional sessile bulblets; capsules and seeds
often formed; flowers tristylous, rarely homostylous.......................…..…….Oxalis latifolia
I seem to have both these species in my collection, and would upload both.
Here is Oxalis intermedia A. Rich. from Chakrata and along Mussoorie Chakrata road.
Oxalis intermedia A. Rich., Hist. Phys. Cuba, Pl. Vasc. 315. 1841
syn: Oxalis dehradunensis Raizada, 1976; Ionoxalis intermedia (A. Rich.) Small, 1907
This stemless species species is distinct from O. latifolia in leaves arising from a cluster of small sessile bulblets, leaflets broadly obtriangular leaves with usually acute angles and flat upper edge, larger green leaflets 30-40 cm long, smaller purple flowers more in number. 
Thanks Sir for the Clarification

Thanks, ..., That means all species we considered as Oxalis dehradunensis should now be put under Oxalis intermedia. Pl. confirm so that I can make necessary changes in efi site.
Yes ...
The difference in size of the leaf seems to be very little.
What is important to look at in the field is the bulblet... single (Latifolia) Multiple(Intermedia) and the
style.
Tristylous in latifolia.
Am I clear? Hope so.
Catalogue of life now gives Oxalis intermedia A.Rich. as a syn. of Oxalis latifolia subsp. latifolia
While it (CoL) and POWO give Oxalis dehradunensis M.Bieb.Raizada as an accepted name.
Does it has any bearing ?
Oxalis richardiana C.R.Babu is give as a syn. of Oxalis dehradunensis M.Bieb.Raizada as per CoL and distribution given is only India.
I do not find any specimen of Oxalis dehradunensis M.Bieb.Raizad in GBIF, while there are 1018 specimens of Oxalis latifolia Kunth in GBIF.
After pursuing all posts in efi site at Oxalis intermedia and Oxalis latifolia subsp. latifolia, I am inclined to put them all under Oxalis latifolia subsp. latifolia as I hardly find any visible difference between the two.
As most of the species have been introduced from outside, than how are we going to have a species like Oxalis dehradunensis M.Bieb.Raizada, with distribution only in India ? It is also not mentioned in eFloras, where only Oxalis latifolia Kunth is mentioned.

Came across this herb at Purundar Fort, Maharashtra
Bot. name: Oxalis dehradunensis
Family: Oxalidaceae.
Date/Time: 31-07-2010 / 12:00PM
Habitat: Wild
Plant Habit: Herb

O. intermedia, pl see discussion in another thread.
O. intermedia which has been noted as O. dehradunensis is found growing in shady places of Ranchi, of Jharkhand state of India during winter season, flowering from the first week of February to the end of the month.
Here is the image taken by Dr. M. P. Mishra in Jan 2014.
Details about nomenclature of this plant are given in this thread

Yes it will produce flowers in spring or early summer. It is a noxious weed in Uttarakhand propagating rapidly by underground tubers.

In my garden in Bangalore
I have found similar variety, but with light violate color flowers, the leaves bigger in size and the leaves shoot directly from the bottom, with no "branches". Can it be Oxalis barrelieri: Lavender Sorrel (http://en.wikipedia.org/wiki/Oxalis_barrelieri) ?
