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