Forwarding again for any assistance in the matter please. Some earlier relevant feedback:
If one belives these websites and some indications on Flora of China websites, majority of my (and may be others also) phototographs presumed to be O. corniculata may actually be O. stricta: http://oregonstate.edu/dept/nursery-weeds/weedspeciespage/ OXALIS/oxalis_species.html http://www.cals.ncsu.edu/plantbiology/ncsc/containerWeeds/Oxalis_ corniculata_stricta.htm The same feeling I get when I make search of Google images for these two species. May be Santosh ji will help us to solve this confusion. -- Dr. Gurcharan Singh Here is the pdf of second paper on caulescent species of Oxalis by the same author Nesom, published in 2009 in J. Bot. Res. Inst. Texas 3(2): 727 – 738. 2009. It should help further: -- Dr. Gurcharan Singh Thank you very much for focusing our view towards this major issue and providing us differences between two allied species of *Oxalis*. Fortunately, the specimen of *Oxalis* L. which I have posted on 4thMarch, ( https://groups.google.com/forum/?fromgroups#!msg/indiantreepix/xOQh8-8DEZg/ Yv9orRkLJ5sJ) has been worked out by my PG students of Scottish Church College in their practical lab and after matching with keys from local flora we confirmed its identity as “*Oxalis corniculata*L.” Moreover, much pubescent nature of the margin of leaflets (in comparison to *O. stricta*L.) can be viewed after zooming the picture. The plant was creeping, NOT erect to decumbent and without any stolon I remembered. Please share the distributional range of *O. stricta* L. Regards, Sukla I think the attached photographs (recorded this morning, beside our kitchen drainage) are of *Oxalis corniculata* L., because, as per FoC - 1. petioles are not pubescent in *O. stricta* L. - http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242416902<http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242416902> 2. peduncles are not 2x or more longer than petioles - http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242416902<http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242416902> But, fruiting pedicel seems to be erect in my photographs. Thank you. Regards, surajit At the begining of this week I had thought that perhaps we will be able to hunt out O. stricta. In fact at one stage I thought I had found one, but then I had to give up, because I was not satisfied. That is why I had withheld my upload of Oxalis corniculata, it was my last post today in frustration. -- Dr. Gurcharan Singh I have memorized keys of both the species. I searched last two days if i could find *O. stricta*, but there wasn't any. FoC says it is found in forests and ravines at 400-1500 m. Regards, surajit ---------- Forwarded message ---------- From: Gurcharan Singh <[email protected]> Date: 4 March 2013 14:31 Subject: [efloraofindia:147944] Balsaminaceae, Geraniaceae and Oxalidaceae Week: Oxalidaceae-Looking for Oxalis stricta..kindly shuffle through your collections of O. corniculata To: efloraofindia <[email protected]> Dear members I request you to go through your collections of Oxalis corniculata for possible specimens of Oxalis stricta. The two species are very closed and can be easily confused, but following features should help: Oxalis corniculata: Plants mostly creeping, stolons absent; flowers in umbellate cymes or solitary; fruiting pedicels deflexed to horizontal Oxalis stricta: Plants erect to decumbent; stolon present; flowers in a cymose inflorescence; fruiting pedicels erect. Kindly don't get confused by the photograph on Flowers of India which on the basis of larger flowers in an umbel, absence of any stem and leaves in the photograph apparently belongs to O. pes-caprae and not O. stricta -- Dr. Gurcharan Singh Retired Associate Professor SGTB Khalsa College, University of Delhi, Delhi-110007 Res: 932 Anand Kunj, Vikas Puri, New Delhi-110018.
