Certainly not O. pes-caprae

Might be O. exilis (key on p.302 of Stace) but I doubt there is enough information in this photograph to determine. Inflorescence appears one-flowered?

O. exilis was my second thought...

... as it did look as though there might be just solitary flowers, and comparisons such as "smaller and more slender than..." are really unhelpful when trying to ID from photos.

But I felt it more likely to be the common one, so that's what I decided to go for.

It really does help to have more than one photo of the same plant, from different angles (including underneath the flowers, so that sepals can be observed).

With what we have, I think O. corniculata is the sensible ID.

In this case ...

... a face on photo of a flower, so we could count stamens, would have resolved the question.

I do have more images, not

I do have more images, not sure if they will be of any further help. Will put them up asap.

I see five stamens so O.

I see five anthers so O. exilis unless I am misinterpreting.

Rachy Ramone's picture

Yup...

...I agree, only five anthers to be seen *sigh*, I retract my ID!!

MJB, please put up the correct ID so we can agree with it.

Mick, you might like to...

... go back to one of your earlier postings of Oxalis, the photo is a bit fuzzy but it also appears to have only 5 anthers, so it may well be another occurrence of this one.

These photos will not answer the question

of number of stamens.

The second ring of stamens (if they exist) could very well be deeper in the corolla tube than what is visible here.

Do you have more pics?
