I know Oxalis is hard to identify to species level. Do I have enough characteristics?
   7 Feb 2019
I've gone Oxalis corniculata over O. perennans because the hairs on the stem do not appear to be noticeably upward pointing and the brown stipule appears truncate and membranous, but I am fairly uncertain re the ID. I assume it has yellow flowers

Hairs on he fruit are also suggestive of Oxalis thompsoniae

Every key/description picks different features but going by yellow flowers, hairy 15mm seed pod and taproots I would go for Oxalis corniculata. Flora of the ACT says this is a "cosmopolitan species represented by at least two local forms" so there is still work to do..

Though Flora of the ACT is an excellent book with a lot of information not available anywhere else, it does predate the publication of a whole swodge of species of Oxalis, which at the time it was published, were all lumped into Oxalis corniculata. I find the direction of hairs on the stems and the presence and shape of stipules is a good start to IDing.
The narrow capsules and squared off stipules at the bases of the leaf stalks are pretty well indicative of corniculata.

Thanks Betty. Botanists have certainly kept busy. I wish I could see some of the work without paying $40 per paper.

Go to the National Library. If the journal is published in Australia, they must by law deposit a copy there. It is a bit of a pain because you have to order what you want from the stacks and wait till someone brings it. Then there is a small fee for photocopying.
Take out a membership of Friends of the Australian National Botanic Gardens. If you are a member of any of their interest groups including the monthly Monday talks, you can go to the library and photocopy for free.
