﻿MR. J. MIERS ON THE LECYTHIDACE^. 291 



w — 



broad, the latter, descending to a length of 3 in., is plug-shaped, as in Q. Brasiliensis, 

 but larger and more obconical, it is triquetral, the angles archingly united J in. below the 

 summit; the seeds are 17 lines long, 3 lines broad, membranaceously winged below, 

 with an apical embryoniferous escutcheon, obliquely oblong, 5 lines long and 3 lines 

 broad.

10. Allantoma (Plate XXXVI. a). 



The very peculiar structure of the androphrorum and of the seeds readily distinguish 

 this genus from Cour atari, its peculiarities having been already noted (ante, p. 170).
