* Seeds of this plant wliich were sown in the Honorable Company's Botanic Garden at 

 Calcutta, on the 2d November 1835, commenced germinating on the 18th of the same month. 

 Of these I have examined two in an early and dried state. The integuments were ruptured 

 irregularly at their apices and the wing had totally disappeared. The inner one had become 

 quite distinct, the albumen had disappeared. The radicle had reached a considerable length. 

 The cotyledons were for the greater part enclosed within the integuments, but had enlarged 

 and assumed a greenish tint. No plumula had b«en developed.
