 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. — Brown MSS.
