252 DEVELOPMENT OF THE FLOWER. 
My impression is, that Cruciferz are 4-carpellary, and that 
the possibility of the abortion of the lamina of carpellary leaves 
is pointed out by Escholtzia or Chryseis, in which there are 
certainly 4 stigmata, and 4 carpellary leaves ; two of which — 
are as in Cruciferz, reduced to narrow placentiferous strips.

a. —In the Kunkree, Cucurbita, the triangular placentz will 
be found when the bud is 34 lines, to run up into the lobes 
next the lines of greatest separation of the stigmatic divisions. 
b.—This stage is too late to determine the question, for 
cohesion has taken place between all the stigmata. Do these 
prove the real stigmata? A transverse section of the same 
shews a great similarity to a leaf turned in : outward, the axis 
too has something that looks much like a vascular bundle. 
c.—The lesser stigmatic sinuses again, correspond to the line 
of approximation of the triangular placente; these stigmatic 
lobes will, I think, prove to be the true stigmata, and if so, it 
will be fatal to Wight’s views pn this point, because the style 
will then alternate with the supposed carpellary leaves. 
The section of the signs ht maturity undoubtedly repre- 
sents a similar apparent inversion, the edges being turned 
in, so that each» styleshas Å cavity to which the stigmatic 
surface reaches along the line of inflexion, but terminating at 
the edge of the margin: the remaining surface of the cavity 
is not stigmatic ; and what is worthy of attention is, that it is 
lined with hairs, analogous to those of the tube of the calyx. 
It is also remarkable, that there is no dorsal vessel to what 
appears to be the uns although otherwise it is highly vascu- 
lar 
The aryna canal itself is ordinarily cónstituted, it has 
as many rounded angles as there are carpellary leaves, the 
faces corresponding with the actual lobes of the style, the 
angles, with the lines between the placentæ. Its whole surface 
is stigmatic. +
