« With all the authors above quoted I regard what Lin- 
* nus has called calyx and corolla in Есрноввіл, as an 
* involucrum, containing several staminiferous flowers 
** which surround a single pistilliferous flower. By some of 
“ these authors the staminiferous flowers are described as 
“ monandrous (one-stamened), and in this respect, also, 1 
“ agree with them; but the body which all of them describe 
“ as a jointed filament, 1 consider to be made up of two 
“ very distinct parts, the portion below the joint being the 
* footstalk of the flower, and that above it the proper 
* filament: but as the articulation itself is entirely naked, 
* it follows, that there is no perianthium; the filiform or 
* Jaciniated scales, which authors have considered as such, 
* being on this supposition analogous to bracteze; the pis- 
* tilliferous flower, in conformity with this supposition, has 
* also its pedunculus, on the dilated, and in a few cases 
& obscurely lobed, apex on which the sessile germen is 
“placed. If this be a correct view of the structure of 
“ EUPHORBIA, it may be expected that the true filament, or 
“ upper joint of what has commonly been called filament, 
* should, as in other plants, be produced subsequent to the 
** distinct formation of the anthera, which consequently will 
“be found at first sessile on the lower joint or peduncle, 
“after that has attained nearly its full length; and accord- 
* ingly this proves to be the case in such species as І have 
* examined. Additional probability is given to this view by 
* the difference existing between the surfaces of the two 
* joints in some species. I consider it, however, as abso- 
* lutely proved by an unpublished genus of this order, hav- 
* ing an involucrum nearly similar to that of EUPHORBIA} 
* and like it, inclosing several fasciculi of monandrous 
< staminiferous flowers, surrounding a single pistilliferous 
* flower; but which, both at the joint of the supposed fila- 
* ment, and that by which the germen is connected with . 
“ its pedicellus, has an obvious perianth, regularly divided 
* into lobes.”
