I looked up this species last night in Goldblatt & Manning's amazing 'Cape
Plants' which gives a brief description of all known plants from the Cape
floral region of South Africa. The author of the Oxalis account, B. Bayer,
says of O. natans: Aquatic geophyte with slender flexuouse, branching stems.
Leaves tufted and terminal, trifoliate. Flowers shallowly campanulate, white
with yellow tube. Sept.-Nov. seasonal pools, 50-200 m, Piketberg to Cape
Peninsula and Worcester.

I would love to see it! The description puts me in mind of Crassula natans,
which I saw in the Nieuwoudtville area in Sept 2004, a pretty thing with
floating rosettes and a tuft of white flowers, all held on long flexuous
stems rising from the pool bed. Presumably both Oxalis and Crassula have a
storage organ in the pool bed and I should think they can adjust their habit
of growth dependent on the depth of water.
