Any leaves ?

Why the colour look different from images at Oxalis debilis var. corymbosa ?


For me the ID is correct.


I was also surprised to see different colour but guessed it could be O. debilis. Since it is from my old collection I have only these pictures.

This should be..Oxalis debilis ..


I think we only have Oxalis debilis var. corymbosa as per Oxalis


As per latest version of The Plant List, an also USDA (includes images too); O violacea L. (Ref. – Voigt) is an accepted species, not a synonym of O. d. var corymbosa. Please check also – http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=l340

Would like to know more.


Thanks, … I have corrected Oxalis debilis var. corymbosa accordingly.


Should be Oxalis debilis, as … pointed out.


Thanks, …, We have Oxalis debilis var. corymbosa only as per Oxalis.

040911-MS -43- ID confirmation of Oxalis species:  I am attaching the photographs of Oxalis species. Photographed on 16.6.2009.  Place.   Muir Woods, California.   The herb is almost everywhere in the National Park forming a thick mat.  It is also common in other wet places in California.


Leaflets 3, obcordate, flowers small pink would be Oxalis debilis var corymbosa, a garden weed originating from tropical America.

Beautiful pictures. The texture seems to be unique for clinching ID (My opinion. Not seen this so far)


Thank you Sir, but failed to understand what texture – is it pubescent pedicel? Or is it brownish tipped sepals?


I meant to say my subjective feeling of the texture of the petals. Nothing botanical will describe it. Something you feel from within when you compare two different flower specimens…a visual impression one makes; though not scientific.

Oxalis debilis var. corymbosa


Thank you very much Sir, never thought of or experienced anything like this.

Yes there is mixing up. The flowers in fact belong to O. martiana (and not O. maritima which has yellow flowers) now correctly known as O. debilis var. corymbosa . The leaves perhaps belong to some malvaceous member

Hooghly Today : Oxalis debilis var. corymbosa (DC.) Lourteig: FoI features this plant, FoC & FoP describe it and The Plant List gives synonyms. I couldn’t find it in “Bengal Plants” or “F. B. I.”, but “Hortus Suburbanus Calcuttensis” refers it as Oxalis violacea L.
I found this herb today (16.1.13), beside a village-drainage, by the side of a front-yard.


Oxalis debilis is also a common herb here in Uttarakhand found in the foothills of Himlaya and Tarai areas. It is yet not flowering here and will bloom only March onward due to subtropical climate.

It was my first sight of this plant, though i have seen photographs from my friends in North Bengal and Assam.
Thank you very much for confirming the ID.

Sharing pictures of Pink Wood Sorrel, Oxalis corymbosa from Mahabaleshwar seen in a Strawberry field.
Pictures taken on 17/4/09.
This was posted on our group and identified by … and …


… the identification is correct but following Nessom (2009)- I have uploaded both papers one on acaulescent species and one on caulescent species on two separate threads-it should be named as O. debilis. The two species differ only in the distribution of oxalate crystals, O. debilis gets priority in naming.

First Photograph is awesome.


Both GRIN & The Plant List treat the following under two different taxon with different synonyms:

The Plant List 2 GRIN 2 (Oxalis debilis Kunth var. debilis)

Would you pl. further clarify the position ?


There are two taxa
Oxalis corymbosa DC., 1824
Oxalis debilis Kunth, 1822
There are some authors who follow Lourteig, 1980 who treated these two as two different varieties of same species. Since O. debilis is earlier published name so it gets priority and as such O. debilis Kunth becomes O. debilis Kunth var. debilis, and O. corymbosa becomes O. debilis Kunth var. corymbosa (DC) Lourgeig, 1980
I am following the treatment by G. L. Nessom (December, 2009) who thinks there is no need to treat them as two different varieties as there is no reliable character except distribution of oxalata crystals. So both are treated simply as O. debilis. His work is most authentic recent treatment of the genus.

Introduction: Ashwini Bhatia : 1 correct image as above.

I have just joined your group. I live above Mcleodganj in Dharamshala, Himachal Pradesh at an altitude of about 1700m. There is a profusion of wild flowers, ferns, weeds and several other plants that I do not yet identify.
I enjoy photographing the birds, butterflies, dragonflies and plants of the area as a hobby.
I am looking forward to an exciting exchange at the group.

…………………………..


Yes, it is lovely here. I had a nice walk in the mountains today with my family. The mountain sides are lined with begonias, balsams, violets, sweetbox, maiden’s hair fern, dog flowers and other wonderful wild plants. I hope to gain from this group’s expertise and identify the local flora correctly in the coming days.
I will post some pictures from the walk tomorrow. Here is a Large-flowered Pink Sorrel (Oxalis debilis var. Corymbosa). I photographed it on my phone yesterday (30.8.14). Please correct me if I have a wrong ID.


what did the leaves look like?


Unfortunately, I couldn’t see the leaves. The flower stalks were jutting out from below a municipal water pipe next to a narrow road with traffic. I did stoop low to see but was not successful. I have another picture of the flowers from the top if that helps in the ID.
Thank you for your help. …, did you see my email answering your query about the Daisy Fleabane?


yes, yours is a fleabane no doubt, …
but i am not a botanist, so cant be sure about the classification based on that one pic…

the only fleabane i am more familiar with is e. ramosus with rather white or faintly pink petals.

lets hope … will reply soon.


Hearty welcome to our family …, Yes seems to be Oxalis cormbosa


Thank you very much … I will try and be a useful member of this family.

Oxalis debilis var. corymbosa (DC.) Lourteig : 5 posts by 3 authors. Attachments (8)

Habit:Wild.


Oxalis debilis Kunth seems to be the correct name !

Flora of Pakistan, Flora of China and Checklist of Nepal only list Oxalis corymbosa DC.(syn. of Oxalis debilis var. corymbosa).
Also Catalogue of Life gives range in Nepal for this only.
Oxalis corymbosa and O. debilis were differentiated by A. Lourteig (2000) primarily by the distribution of oxalate deposits in the leaf lamina. In O. debilis, the dotlike deposits are crowded along the margins and absent to distinctly less abundant elsewhere. In O. corymbosa, the deposits are evenly distributed over the whole lamina. In their native range in South America, the two expressions are broadly sympatric and intermediates are common, as they are in the flora area. Intermediates have the oxalate dots along the margins as well as over the whole surface or sometimes mostly on the outer third of the blades, near the margins. There is no justification for formal recognition of two entities.”
So we follow Oxalis debilis var. corymbosa only.


Please look into the links.
