Madagascar? L’habitat de cette plante reste douteux, ainsi qu’il résulte 
du passage suivant emprunté à M. Stapf 2 : « The plant now described 
was raised from a cutting presented to Kew in January 1908, by 
M. G. Bouvet, Director of the Jardin des Plantes at Angers... In trans- 
mitting the plant Mr. Bouvet stated that the species appeared to hâve 
been originally introduced with other plants sent from Madagascar to 
I) 1 Bontemps of Saumur. Since then, however, Mr. Bouvet lias learned 
1. Parlant des étamines, Stapf remarque : « ... theabsolute length of the 
stamens is subjectto some variation, and occasionally some of the stamens 
may become much reduced or may even be suppressed ». Cette variation 
tient uniquement à Finfluence de la culture.
