New Oxalis pictures on the wiki

Dear All and especially Fred,

I'm downsized some pictures to add to the wiki, especially for all you 
flower deprived folks where winter has everything covered with snow or too 
cold to bloom. I'll be adding them in batches as I have time. The first two 
are Oxalis from Telos. One bloomed in October and the other one, Oxalis 
livida, did not bloom, but has leaves a lot like one of the unknown species 
that Uli collected in South Africa so I thought it useful to add the leaves 
for comparison sake. I just got one bloom from the Uli bulb (Uli76) also in 
October but the color of the flower was right. These plants are good ones 
to photograph with a digital camera so you don't feel so bad when you 
delete almost all the pictures you take as not worth keeping. The leaves 
are very tricky to photograph. The other unknown from Uli (Uli 63) is a 
very charming plant that has been blooming since December. It has nice 
bright yellow flowers. When I was looking at my Cape Plants book which has 
a key of sorts, I noted that not very many Oxalis in the Cape have a 
peduncle with more than 1 flower (only 9). Since he found this plant near 
the Nieuwoudtville pass that eliminates quite a few of the species which 
are found elsewhere. There are only three left and one of them is Oxalis 
livida with rose or lilac flowers and very different leaves. That leaves 
two: Oxalis pes-caprae and Oxalis compressa. By process of deduction I 
suspect it is the latter.

So what do our Oxalis experts think? Any other ideas about these two 
mystery plants?

The wiki page is pasted below, but since it may be hard to find what I've 
added since that page has a lot of data and pictures on it, I've copied the 
new sections below. More to come (Crocus, Romulea, Narcissus, more Oxalis, 
Lachenalia, Gladiolus) as I have time.

Oxalis engleriana grows on shady southern slopes in the Northwest and 
Southwest Cape. It blooms in the fall and has 5-8 linear to linear-oblong 
leaflets and a rose or violet flower 3 to 4 cm with a narrow yellow tube.

Oxalis livida has trifoliolate leaves, usually hairy, with deeply bilobed 
leaflets that are purple beneath and rose or lilac flowers with a yellow 
tube. It blooms in fall. It is found on rocky slopes in shade in the 
Northwest and Southwest Cape. My plant did not bloom, but I found the 
leaves quite fascinating and extremely difficult to photograph as they 
blend into the background and don't look as attractive as they are. Photo

Oxalis sp. Uli63 collected by Johannes-Ulrich Urban outside Vanrhynsdorp in 
hard gravel forms a rosette of bright green leaves with reddish-brown stems 
and many bright yellow flowers blooming above the leaves in winter. Could 
this be Oxalis compressa which is found in the Northwest to Southwest Cape 
and has more than one flower in the peduncle (2-6), trifoliate leaves and 
compressed leaf stalks and is often confused with Oxalis pes-caprae which 
it reminded Uli of but seemed more refined?…

Oxalis sp. Uli76 collected by Johannes-Ulrich Urban at about 500m. on the 
Nieuwoudtville Pass in fynbos habitat. This species blooms in the fall and 
has pink flowers and deeply bilobed leaves that sometimes look purple and 
sometimes green. Could it be Oxalis livida?……
