Stem branches rough hairy. Leaves serrate alternate 5-8 cm ovate acute triangular or lobed' appressed hairy. Flower heads 0.4-0.8mm across.

Achenes 1cm bye 0.4 cm oblong or ovoid. Compressed black. Xanthium strumarium (Rough Cocklebur, Clotbur, Common Cocklebur, Large Cocklebur, Woolgarie Bur) is a species of annual plants belonging to the Asteraceae family.[1] The species is monoecious, with the flowers borne in separate unisexual heads: staminate (male) heads situated above the pistillate (female) heads in the inflorescence.[4] The pistillate heads consist of two pistillate flowers surrounded by a spiny [involucre]. Upon fruiting, these two flowers ripen into two brown to black achenes and they are completely enveloped by the involucre, which becomes a [bur]. The bur, being buoyant, easily disperses in the water for plants growing along waterways. However, the bur, with its hooked projections, is obviously adapted to dispersal via mammals by becoming entangled in their hair. Once dispersed and deposited on the ground, typically one of the seeds germinates and the plants grows out of the bur.

Family : Asteraceae Marathi : Shankeshwar शंकेश्वर A weed common on roadside Observed flowering in open areas around Pune city last few days Large herb Annual about 1m in height. Stem branches rough hairy. Leaves serrate alternate 5-8 cm ovate acute triangular or lobed' appressed hairy. Flower heads 0.4-0.8mm across. Green when young in terminal and axillary spikes.Barren heads crowded at apex. Fertile heads fewer. Fruits 2cm long with 2 erect mucronate beaks covered with hooked prickles. Achenes 1cm bye 0.4 cm oblong or ovoid. Compressed black. Yes the identification is correct, but I fail to understand how Xanthium strumarium, a much earlier name be synonym and X. indicum, the accepted name I may be complete wrong but grin shows Xanthium indicum to be the syn of X strumarium but I felt is not the accepted name
Agreed it has to be vice versa. Thanks for pointing out that. Even The plant list has something else to say. I cant go more deeper in that context. There are many provisions in ICBN to conserve names which may actually be wrong. Article 14.2.of ICBN says, "Conservation aims at retention of those names which best serve stability of nomenclature". Stability like, the name of family Orchidaceae Juss., Gen. Pl.: 64. 4 Aug 1789. is conserved against Orchidaceae Adanson, Fam. des plantes 2: 68 1763. Just based on the popularity of usage, Xanthium indicum may be considered conserved, but it is not yet conserved, as atleast the plant list or GRIN doesnt consider them as same. For this particular case, it is yet to be resolved according to The Plant List and both are till now considered distinct species with Xanthium indicum Roxb. is an unresolved name but synonymous with Xanthium inaequilaterum DC.. WHEREAS Xanthium strumarium L. Sp. Pl. 987 1753 is an unresolved name.
But interestingly Xanthium strumarium (without any author) is accepted name according to the Plant List, with X. chinense Mill. as synonym I am tired of pointing out corrections to them. Xanthium strumarium Elliott Sketch Bot. S. Carolina 2: 479 (1823). This is the full citation of the same name. I understood your point. May be once the other strumarium is resolved, they will be able to resolve this one also :). Yes ... I found it out from IPNI and Compositae Checklist. Here in Maharashtra we get mostly one species i.e. Xanthium strumarium L. which is seen as a roadside weed, no doubt its an introduced species. Xanthium indicum Koeng. ex Roxb. is synonym of X. strumarium i guess, if its a reliable different species atleast i have not seen it. it will be great if someone upload both species photographs on the site.. Yes ... X. strumarium L. and X. indicum Roxb. are same species as per most databases and publication, but looking at the fact that X. indicum was described from India nearly more than 200 years and X. strumarium described in Clarke Compositae Indicae nearly 150 years ago, it may not be appropriate to call is an introduced weed at this stage. But there is another species X. spinosus, which has been recently introduced in Kashmir, and was uploaded by me on Flowers of India. Sirji i guess people called the same species as X. indicum instead of X. strumarium before Clarke cleared the things. Yes that must be true Please find the lectotype of Xanthium strumarium attached for reference. ... can you please check if this is the same which grows in Maharastra. We need to check Xanthium indicum too. yes this what we find in Maharashtra and adjoining area.. Can anyone please get the protologue of Xanthium indicum from Hortus Bengalensis? I remember during our school days we used to throw the seed pods on the back of our friends and enjoy the sight. In scientific terms you were actually dispersing its seeds, which is the usual way of doing it, otherwise in nature, it get stuck to other animals or even human beings and get dispersed. In technical terms exozoochory Though the post has the ID agreed, it remains unconcluded in anticipation of getting the protologue of Xanthium indicum from Hortus Bengalensis. Hopefully someone may be able to provide.

A noxious, foetid weed.
Yes a very common weed in plains Now correctly known as Xanthium strumarium.
This is Xanthium strumarium.
Yah Historical Plant................ same story here also. We used to keep dry fruits below the taat-patti also (on which we used to sit, as no benches were there)
So, it turns out to be a very popular plant with lots of sweet nostalgic memories.

These shots were recorded from Chakrata area, though common elsewhere also.. Xanthium strumarium.. Yes, very good pictures.

Common weed photographed at the roadside at Yavteshwar near Satara. Bot.Name: Xanthium indicum Family: Asteraceae Local name: Shankeshwar X. strumarium should be the correct name.
