Title: Which Oxalis?
Post by: Lvandelft on August 23, 2011, 10:32:49 AM
Does anyone know what the name of this Oxalis is? The flowers are looking like O. pes-caprae, but it is not this weedy one!

Can't help you with the name Luit, but if it's NOT the weedy one as you state, it IS a good one !  :D

Luit,

O. pes capre has multiple flowers on a single stem (and umbell?), so yours definitely couldn't be it by the look of it.

I'm afraid this does not help me much but Paul's statement makes me a little bit happy though  :D ;)
Just found out that we have Oxalis pages as well and will put my question there too.

 Luit, some of the Oxalis page contributors have not only posted lots of phtos of different Oxalis, they also have links to their Oxalis websites ******.... hope you can get some assistance there!

 Pretty yellow but I can't give a name.  :-\

 ****** edit by maggi: of course, now I try to find them, I can't!  :-[

Haven't tracked down the  website I was thinking off, yet.... but here's the thread with the pictures from Dabi, the Taiwanese enthusiast

O. valdiviensis, possibly?

If so, it seeds about gently here.

Maggi, thanks for your efforts. I just found and scrolled before all pages of Dabi, but I did not find it there.
I got a hint with the name of O. uliginosa??  but I never saw this plant personally. Oxalis has many look alikes I'm afraid  :), but maybe some of the S. African  Forum members might have seen it?

The Oxalis uliginosa depicted in the following image possesses deeper flowers.

If it is the species of course.
The species are greatly similar to each other. For me certainly. For example
http://www.telosrarebulbs.com/images/pur-Yellow.jpg
seems to be a possible candidate too.

Thank you Josef. The problem is that many yellow flowering oxalis are on pictures looking almost the same.
I don't think that the plant on my picture is a O. purpureum. They have mostly much bigger leaves.

Luit, your plant looks like a form of O. obtusa a bit thirsty. This species has infinite color forms. The bulb with several prominent ribs is quite distinctive. You will have to take a photo of the bulbs when they are dormant.

Thanks Alberto! But I don't think it's an O. obtusa, I've grown them by the 100.000's and what I know is that the obtusa flowers are much bigger.
It is not my own plant, but maybe I'll see some bulbs next spring??

Certainly. Including Oxalis stricta if photographed at suitable angle.
The parts covered  below the surface might be interesting too.
