STIGMA, 77 
In this case it is assumable that the pollen tubes pass in 
immediately, not first proceeding to the summit. In many 
cases the true passage of the stigmatic canal is only deter- 
minable by fecundation. 
[The stigmatic tissue is decided ; ; it surrounds the whole 
base of the stigma, being the base of the upper part of the 
fissures, it passes down converging into the stigmatic canal. 
The style has a large canal, filled with stigmatic tissue, of 
lax, variously shaped cells, with lax greenish globules, the 
brous tissue of which has one dorsal vessel, around which 
are cells. 
The difference in aspect between the disc of the stigma 
and the margin is obvious ; the one is green and cellular, the 
other mucilaginous-looking: in consequence of the furrow 
in the stigma along the line of sinuses, a transverse section 
at particular portions will present bilobed angles. 
Few cells,if superfices are once out of the lac 
sac,—tinged, grumous spot at apex of nucleus,—no sac,—no 
vessel, 
Style where united is certainly papillose, the cells appear- 
ing to radiate from two purplish spots, between which is 
the softest tissue, i. e. the stigmatic canal, the whole style stig- 
matic, except the dorsum and tissue round the dorsum vessel. 
A series of transverse sections shew, that these pink spots 
radiate as they pass up, until they become semi-circular 
lines,* 
In Cordia, Plate 30—Fig. 4, the ovarial vessels are imd; 
the styles are apparently two, each bipartite; and each branch 
has a vessel, the bifurcation taking place a little below the 
division of the branches of the styles a, etc. 
The stigmatic surfaces are limited to the inner faces of 
the divisions. The explanation is twofold, either there are 
two carpellary leaves, the styles being bilobed, or there are 
four, in which case the vessels of the ovary will be limited 
`~ to two of the sinuses of adhesion. 
There is an amount of laterality, which favours the former 
supposition, but then the vessels of the style should end at
