NAMES AND OBSERVATIONS ON INDIAN PLANTS. 551 



position of the antheriferous stamen in Scitaminece and that 

 of Cannece or Marantece, and have remarked that this 

 difference is in some degree analogous to that existing 

 between Cypripedium and the other genera of Orchidea} 



Apostasia in its trilocular ovarium differs from all the 

 genera of Orchidea ; but an analogous difference occurs in 

 Scitaminece, in which Globba is distinguished from every 

 other genus in having its ovarium unilocular, with three 

 parietal placentae. And in both these families it may be 

 proved that the constituent parts of the compound ovarium, 

 whether unilocular or trilocular, agree in position or in 

 their relation to the divisions of the perianthium. 



Lastly, Apostasia, in the economy of impregnation, or 

 the state of the pollen, and the manner of its application to 

 the stigma, probably differs essentially from all Orchidece, 

 except perhaps Cypripedium and possibly Vanilla. But 

 a similar difference, and in a degree still more striking, 

 exists between Apocinea, as I have formerly proposed to 

 limit that order, and Asclepiadece, which can only be 

 regarded as a subdivision of the same natural class. —
