This very pretty and quaint species was originally dis- 
covered by Commerson in woods near the village of 
kéchousamenti, in Madagascar. According to Boissier, it 
was also collected by Boivin in the island of St. Marie. It 
was for some time in cultivation in the Jardin des Plantes 
at Paris, but seems to have disappeared long ago. It was 
rediscovered by Mr. Scott Elliot in woods near Fort 
Dauphin in 1889, and subsequently introduced into France 
from the same locality by M. Godefroy-Lebeuf, who 
communicated a specimen to Kew, where it flowers annually 
in the Succulent House. 
Descr.—A small, erect, glabrous shrub, Stem woody at 
the base, otherwise succulent, simple, or very sparingly 
branched, five-angular, the angles crested by the large 
vertical almost confluent deeply lacerate persistent — 
stipules. Leaves in tufts at the ends of the stem and 
branches, obovate-spathulate or oblanceolate, long at- 
tenuated at the base, obtuse at the apex or subacute, 
apiculate, with the apiculus folded and recurved (hence
