Unknown Oxalis

[shelagh]

Peter Farkasch who is known to many of the showing fraternity sent me this picture from his mobile phone to mine the other day. He is not technical, I am half a % more technical than he is and at his request have managed to get the pic from the phone to computer. It is a small picture but I hope it may serve.

He calls it Oxalis no name and would like help in identifying it.

It has  a  look of  Oxalis  speciosa about  it, Shelagh - especially  if the  leaves  are  as  furry  as they appear  to be.  It's  one  of  those  Oxalis  the  Wallises  have  Show  success with at the  Autumn shows.

Hi
Peter also sent me pictures.  The first picture shows it with Oxalis melanosticta/speciosa/Ken Aslet to the top right.  The unknown plant is much smaller and has unusual leaves.

The leaves seem quite distinctive, thick and leathery, and heavily veined, which makes it quite unlike any yellow oxalis I know.  Vaguely reminiscent of Oxalis pulchella var tomentosa, but the flowers of that are very different.  I guess it could possibly be a yellow form of Oxalis pulchella, but I have not been able to find a picture of one like this.

Thanks Jon you are obviously many % more technical than me. Let's hope we get a result for Peter.

Perhaps  a  good  idea  to consult Bob and  Rannveig  Wallis - they showed a  lovely  pot  of  O. speciosa with   good  tight  little  foliage  and  flowers  in their  recent  Zoom talk.

Hi Maggi
I remember the plant.  In fact it was probably my picture - Bob asked me for all sorts when he was preparing the lecture.  But in Oxalis speciosa / melanosticta / Ken Aslet (the same plant seems to go by all three names), the leaves are covered in fine silky hairs.  The leaves on Peter's plant are what makes me think this is something different.

Thanks Jon, yes, I think it  was  your  photo.   In the  initial photos of  this  plant  in question  I  thought  the  leaves  were  more  furry  than they appear  in your  later  shots.

Peter says someone has suggested the identity Oxalis lasiorrhiza.  Google finds pictures for that which look a good match.
