Cor'. Gluma duplex, utraque bivalvis; exterior hd^^i excifa. 



From the above generic charafter it appears — that the gluma co-- 

 rolliniE being joined at the bafe by a kind of hinge or articulation, the 

 interior of the exterior i:oroUine glumes is emarginated at the fides of the 

 bafe, or has on each fide a femilunar cavity; — that a rudimentumijlofculi 

 is commonly found atthe bafe between thetwointeriorcorolline valves ; 

 butinthofefpecies where this rudiment is \vz.ntiv\g,2. fquamapetaloidea 

 is feen in its place on both fides, where the interior valve is emargi- 

 nated ; — that the filaments are not inferted in a parallel manner on 

 two fides of the germen, but furround it; the anthercv, however, 

 concealed within the comprefled glumes of the corolla, are placed 

 three on each oppofite fide of the piJliUum\ — that the antherce open 

 only at the top at the time of foecundation ; — and finally, that the 

 St\ks are invariably two, and the Stigmata bijitbata.
