« With all the authors above quoted I regard what Lin- 
** neeus has called calyx and corolla in EvpHorsia, 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, I 
“ agree with them; but the body which all of them describe 
“asa jointed filament, I 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 bractez; 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 
« Evupuorsia, 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 I 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- 
« Jutely proved by an unpublished genus of this order, hay- 
“ing an involucrum nearly similar to that of Eurnorsya, 
“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.”
