order is dodicandrous. The stamina being arranged in 
3 series of which the outermost is incomplete, the two 
lateral ones or those opposite the lateral sepals being 
alone developed, but they are still smaller than the 
others which form the intermediate series, and which 
are consequently opposite the petals. The innermost 
is represented by 4 glands evidently situated on the 
same plane, or forming a single verticel, and these are 
placed opposite the sepals, the two lateral ones being 
placed within the corresponding stamina. I attach 
considerable importance to the fact of the 2 stamina 
opposite the lateral sepals being invariably. smaller, 
asit points out a tendency towards the total disap- 
pearance of the outer series. It will be seen that this 
view accords much with Mr. Lindley’s : particularly as 
regards the incompletion of the outer series.

\ With regard to the composition of the pistillum, 1- 
ücline to Mr Lindley's opinion. I think that there 
are evident traces of 4 stigmata and. consequently of 
as many styles: and these stigmata are so placed, 
ees opposite the sepals, that the idea of their 
puce considerable strength from the consideration of 
the form and structure of the style, and its supply of 
vascular fascicles, these are 4, occupying the axis of
