Tribulus terrestris We call it Go-Khur
Toe or nails of cow. The seeds look like Go-khur. This is supposed to be tonic in Ayurveda. I eat tender fruits. If you consider Tribulus lanuginosus as a distinct species (some authors consider this as synonym to T. terrestris), you may call your plant also with that name (T. lanuginosus). The style is long and glabrous. In T. terrestris the style is absent or very short.
You are welcome …, and thanks for the pictures. The style is very prominent in the fruits, so it is T. lanuginosus. (the style is pubescent in T. subramanyamii, just for info.)
i see this in american southwest hiking trails also and in my potted plants i buy near ganges, too. your pictures are very nice May be Tribulus lanuginosus as per keys and details at Tribulus complex At GBIF, I had gone through various pages, and concluded as follows:
Tribulus terrestris L. … synonyms, sub-species, varieties at GBIF
Tribulus lanuginosus L. … synonym of variety Tribulus terrestris var. bicornutus (Fisch. & C.A.Mey.) Hadidi … status at GBIF
It was too confusing for me to dig into varieties of Tribulus terrestris.
Let me know whether you think posted plant has to be labelled explicitly as Tribulus lanuginosus L. Yes, … Among all the varieties given in Catalogue of Life, only Tribulus terrestris var. bicornutus (Fisch. & C.A.Mey.) Hadidi is reported from India, as per distribution given at the links.
So we may take this one only. I went through links … that you mentioned in your line … “only Tribulus terrestris var. bicornutus (Fisch. & C.A.Mey.) Hadidi is reported from India, as per distribution given at the links.”
It can be seen as follows:
Tribulus terrestris L. India (widespread)
Tribulus terrestris var. bicornutus (Fisch. & C. A. Mey.) Hadidi India (widespread)
Tribulus terrestris var. rajasthanensis (Bhandari & V. S. Sharma) F. Al-Hemaid & Jacob Thomas India (Rajasthan, Gujarat)
As per keys and details at Tribulus complex that you suggested in earlier post in this thread, … poster shows fruits of three species.
In that, I see fruits of my posted plant is much closer to the parent species: Tribulus terrestris than that of Tribulus lanuginosus
What are your thoughts? Tribulus complex This image from my ppt slide has pictures of 3 species of Tribulus. They are distinct in general morphology, style, fruits, thorns, indumentum, leaves etc. as you can see in the pictures. Reproducing the key here: A simple macroscopic key to distinguish the 3 southern indian species : Hope this gives some clarity oin id of these 3 spp. Look forward to your comments/observations. my feedback after 9 years, better late etc etc…. as the saying goes.. thanks
I revisited my own pictures from 2010 when Gokhuru plant had come in as an extra bonus (weed?)
in one of the plants pot, from a nursery from the banks of river Hooghly.
following this key
it is Tribulus terrestris
i have superrimposed … key on his poster to keep it handy. i share it here
1 image.
To me fruits are not visible in your images. Otherwise also, we have to rely more on the key based of Style.  Apologies …, I thought I had seen fruits of this plant, but they were of Pedalium murex. I think I am working very very hard 🙂 I am attaching original photo (of what we see in this post).
Since the capacity of attachment is 8MB, I am attaching only one photo here.
Please check when time permits whether the length of style is negligible / appreciable.
Attachments (1) …, here is another which is not uploaded to flickr because of very poor quality of the photo.
May be this will help in judging the length of style. I hope other aspects (stamens, anthers) help in gauging length of style.
I think the length of style is very minimal.
I was judging based on composite image at at Tribulus complex I sent two original images for your perusal for showing length of style compared to surrounding petals, filaments, anthers. If we go by … images, I think differently. why … it matches … classification. small flowers. very small //short style Is it possible that the pictures in this thread were from two different locations/populations? I am inclined to think the first two pictures as Tribulus lanuginosus based on the longer and glabrous styles. The other pictures may be of T. terrestris as the styles appear to be shorter. The general morphology of the two plants look different, too. But, I could be wrong. You are absolutely right with your thought, … They are from different locations within the premises of a resort.
Referring to my first post on Nov 25, 2019:
The first two photos (one of them is actually cropped version of another) belong to one location- clicked in the morning, and the rest were at another location- clicked in afternoon.
Later I added 2 photos on Dec 8, 2019, one each from the earlier locations.
The first one attached on Dec 8, belongs to morning location.
The second attached on Dec 8 belongs to afternoon.
So shall I conclude that your thoughts are as:
Morning location plant … Tribulus lanuginosus L. … synonym of Tribulus terrestris var. bicornutus (Fisch. & C.A.Mey.) Hadidi
Afternoon location plant … Tribulus terrestris L.
Thank you very very much …, for your thoughts.
…, shall I label my photos at flickr accordingly, else please guide.
I think …, is the expert in this matter and we have to follow his advice. , Tribulus terrestris var. bicornutus in FOI : 4 posts by 2 authors.
Images of Tribulus terrestris var. bicornutus in FOI may be of Tribulus subramanyamii as per keys at Tribulus complex Pl. check. Thanks for the reminder … I haven’t looked at it closely yet. However, the plant on FOI was found in Delhi. If on goes strictly by the given distribution, it would mean Tribulus subramanyamii is found only in Peninsular India. That would mean the plant on FOI is unlikely to be Tribulus subramanyamii. I think there seems to be lot of confusion in this genus as per Taxonomic Status of Some of the Tribulus Species in the Indian Subcontinent by Varghese, M.; Yadav, S.S. & Thomas, J. Saudi Journal of Biological Sciences 13 (1) 7-12: 2006 (keys).
I have added keys at Tribulus with 7 species being reported from India.
Pl. see.
Thanks … Seems like Tribulus lanuginosus … syn. of Tribulus terrestris var. bicornutus (Fisch. & C. A. Mey.) Hadidi is (dis)missed !!  Flora of Kollegala_ID_Please_22072021 PK1: 1 high res. image. Tribulus terrestris L. ?? Yes … May be Tribulus terrestris var. bicornutus (Fisch. & C. A. Mey.) Hadidi as the style appears to be long and glabrous as per keys at Tribulus.
Appears to be a Zygophyllaceae member Tribulus but not sure Most probably T.terristris Pl. check https://efloraofindia.com/2011/04/03/tribulus/ Most probably it is T.terrestris. A common weed here. Neggilamullu in kannada. Ayurvedic medicinal plant. Appears close to images and details at Tribulus terrestris var. bicornutus (Fisch. & C. A. Mey.) Hadidi .
