It is difficult to ascertain the venation exactly, but if the 
filaments are scraped off, each petal will be found to have 
two large vascular bundles, the intervenia being supplied by 
backward anastomosis. Hence it is probable that each is com- 
posed of 3 pieces, and this would explain well the situation 
of the staminoid and stamina or as the petals are simple 
emarginate it is also obvious that they may be composed of 
two, the fertile stamen alternating with them. 
The stamina do not derive their vessels from those of the 
petals which is against the last hypothesis, on the contrary 
these petaline vessels exactly alternate with stamens. 
There is something analogous to an articulat. in the stami- 
noidia, and the vessels of these are more distinct than those 
of the central part. 
The ovula are certainly nucleary, at the time of flowering, 
one is fertilised, and this presents a curious membraneous 
appearance along the side or edge next the placenta. 
Stamina appear equally developed from aa early period. 
The ovula are worth examining, it would seem as if in 
the fertilised but abortive ones, the only ones I have seen 
thereis a tube along the inner edge, and perhaps pro- 
truded from the apex. Fig. II. Pl. DOXXXXIV. 
Although Mr. Brown plainly shews, that the common 
mode of adhesion is in pairs, the want of correspondence of 
the petals, vascular fascicle (3 its excentricity) with the ves- 
sels of the sterile stamens must be borne in mind. s 
hing is easily settled by early observations or by examining 
the venation of those Olacinez with the 5th petal free.
