Mystery plants from Argentina

[Kees Jan]

Any idea what on earth this could be? It is not in Campanulaceae is it? Photographed just outside Varvarco, Neuquen province...

The other mystery plant is a shrub of about 1-2m tall. Is it something in Rhamnaceae? Also photographed just outside the village of Varvarco...

The foliage on mystery plant number one looks a little like an Erodium?

No idea what the first plant is but I think I would like one!!

Only a shot in the dark: No. 1 perhaps a Malesherbia species?

Surely Alberto C (Ezeiza) will know?

Just looked on Chile Flora site and I too think Malesherbia sp. See photo of M. multiflora - the flower buds look very similar, foliage quite rough and hairy, flowers could be similar if central petals brought together as in your photo. Interesting plant!

[Kees Jan]

Thanks, Malesherbia seems to be a good suggestion! Here is another mystery plant, very beautiful, an Oxalis of some sort, photographed in Laguna el Diamante...

I just received an e-mail from John Watson: the Oxalis posted above is the recently described Oxalis chachahuensis

[Lesley Cox]

It may be an overly vigorous one but I do like the speckled flowers and the furry leaves. Very attractive.

[Kees Jan]

The Malesherbia is identified as Malesherbia humilis now!

Edit by maggi: refers to photo 072 in first post
