Though Euphorbia nesemannii is not a spectacular
species. It belongs in a taxonomically very difficult group of species:
the group key 16 according to White, Dyer and Sloane.
It has several interesting charactistics as you look closer at it. Contrary
to most or all other species in this group E. nesemannii is quite difficult
and slow growing in cultivation and thus rarely encountered. It has also
the most western natural distribution in this group: its typelocality
is Robertson, Western Cape, South Africa. In picture 1 is a clone I grow
as E. nesemannii from unknown origin. Does someone grow plants with good
locality-data of E. nesemannii?
During a visit at the beautiful collection
of Jan Nosek in Prague I saw plants, originally coming from the vicinity
of Montagu. These plants looked quite different in having large hairy
persistent leaves. On closer investigation this might prove to be a new
taxa. Can anyone supply me with more information on this find? Are there
more localities with the same or related populations?
