PISTILLUM AND POLLEN. 105 
The ovary is bilocular, yet the style has several fascicles 
of vessels. 
The tube of the calyx presents no demarcations of struc- 
ture, it is uniform, is very vascular, excessively so; pos- 
sessing a number of fascicles in about two series. 
A transverse section shews four vessels, at equal distances, 
two somewhat smaller. 
. [Poinciana. Same mode of development. The apex of 
inflorescence is an aggregate imbrication of cellular bracts 
with empty axils, exactly like the young flower buds which 
are found in the axils lower down, and which are cellular, 
convex, quite entire bodies. Pl. 38.— Figs. 1. and 
Anterior fornicate sepal developed first, before any trace of . 
the others appears, and it always preserves its increased 
development. 'The petals are equal until a tolerably late 
period, when the vexillum is found smaller. Stam. sepalis 
opposita, are most developed, having their anthers quadrilo- 
cular, when the others are mere scales. Pistil a convolute 
leaf, involute towards vexillum or towards axis. a. Stam. pet. 
oppos. ; b. pet. c. Stam. sepals oppos. 
Ovula of latish appearance, marginal. 
Mass (a. Pl. 38.— Fig. 2.) very distinct, a grumous mucila- 
ginous one containing parent cells, with a large thick hyaline 
disk, and 3-4 nucelles grumous, in a greater or smaller state 
of separation. The outer edge of the mass is most developed, 
innermost grumous, here and there dances of granular mat- 
ter. Pl. 38.—Fig. 2. b. c. unequal development the nucelles 
before escape. d.—. A favourable instance for examination, 
the granular appearance of the nucelles seems perpetuated.] 
In Villarsia grandiflora, the parent cells are hyaline, each 
nucelle is distinetly contained in a separate cell ; indeed the 
apparatus looks as if 3-4 grumous nucelles were imbedded 
in a roundish or oblong mucilaginous transparent body, so 
thick are the partitions, so thick the margin of the disc, or 
rather the spaces a he nucelles and the gircumfer- 
ence. Pl. 29.—Fig. 8. a, b 
At this period the Pei A are easily separable, they now 
retain the shape resulting from their confinement, they
