Oss. It will be perceived that I have made a considerable 
and material alteration in the terms of the generic descrip- 
tion from that given by Roxburgh, Fl. Ind. i. p. 102, which 
I conceive to be necessary towards explaining the true rela- 
tions of the various parts of the flower, and thereby affording 
the means of tracing more correctly its natural affinities, 
The principal point is to determine the real nature of what 
Roxburgh calls the nectarial scales at the base of his petals. 
have no hesitation in considering them as abortive stamina, 
which the examination of the flower before expansion, places, 
I think, beyond a doubt. In that state the whole of the 
stamina connive over the pistil, the anther of the fertile 
ones is turned inwards, so as not to be visible and there is no 
considerable difference of appearance between them and the 
sterileones. The anther-bearing hollow of the fertile stamina 
is applied to a corresponding hollow on the side of the sterile 
ones, and at the time of expansion the former separate them- 
selves with a jerk and become erect, while the latter continue 
in their original position incumbent over the pistil. The 
petals on which the fertile stamina are inserted are much 
smaller and narrower than the others, as if exhausted by the 
greater development of the parts they nourish. These 
petals are called by Roxburgh outer laminz of the filaments, 
_ which is contrary to all common analogy, while the other 
explanation might by (be) supported by numerous examples 
of a similar structure. Thus in place of a diandrous flower 
with tripetalous appendiculate corolla and bifid stamina, we 
obtain five as the primary number of all the parts, only 
modified by the partial abortion of three of the stamina.
