The flowers by Frank
This member of the Euphorbiaceae family was
given this name by Werner Rauh and GŁnther Buchloh in 1967. It is found in
central to northern Madagascar, growing in sandy or other well
drained soil with some water and some to lots of sun. The caudex,
most significant on younger plants, can grow to six centimetres or
more, the spiny branches can reach 50 centimetres in length. The
flowers are from greenish over pale yellow to salmon.
Strangely enough, many
sites claims this is a Mexican species. It is NOT, it do originate
from Madagascar! Might be confused by Euphorbia aaron-rossii
A.H. Holmgren & N.H. Holmgren, although the appearance are real
