ON MELIANTHUS TRIMENIANUS. 857 
which in its subfollicular nature, venation, a 
precisely accords with that of Melianthus major ; and lastly, the seed, 
albumen, and embryo. 
The points of difference are those of degree chiefly or only, and 
are confined to the simply-lobed leaves, with no further trace of com- 
position, recalling the analogous difference between Acer and Wegundo ; 
the absence of stipules, or their reduction to the margined base of the 
petiole ; the complete disk, crowned by 8-10 spathulate staminodes . 
the 8 or 10 stamens; more didymous anthers; the minute puncti- 
compare with those of Greyia, these being imperfect in my specimens. 
I have thus, I trust, established the position of Greyia, and would 
only further suggest the following diagnosis of the three genera of 
Melianthea, which may be regarded as subtribes, consisting of a single 
genus each.
