 magnified. Fig. 7, the calyx. Fig. 8, the same, with the sepals thrown back to show the inner 

 basal scales, the ovaries without any disk, the style, clavuncle and terminal stigmata. Fig. 9, the 

 two echinated follicles, one of them in the act of dehiscence, showing two rows of seeds suspended 

 from each margin of the suture by long fleshy funicles. Fig. 10, seeds, shown in different positions, 

 attached at the other end of the ftmicle to a central hUum on the ventral side, the dorsal side 

 glabrous and pluricostate. Fig. 11, a seed deprived of the fanicle, shown on its ventral concave side 

 with the central hilum. Fig. 12, the same, seen at the apex. Fig. 1 3, a transverse section of the seed. 

 Fig. 14, the heterotropous embryo imbedded in albumen. Fig. 15, the embryo extracted, showing its 

 foliaceous cotyledons and superior terete radicle. Fig. 16, the same, shown on its edge : natural size. 



B. Bonafousiaundulata. Fig. 1, portion of the plant. Fig. 3, the corolla in bud. Fig. 3, the corolla with 



the segments expanded. Fig. 4, the same cut open, to show the introflexion of the segments in 

 aestivation, when their tips descend into the mouth of the tube and embrace the summits of 

 the stamens (one is shown expanded) . Fig. 5, the calyx, the sepals being thrown back to show the 

 dentate inner scales, the disk, the ovaries, style, clavuncle, and terminal stigmata : all magnified. 

 Fig. 6, the two divaricated follicles on the thickened pedicel, showing the prominent arching lines 

 on each side. Fig. 7, one of the follicles dehiscing, showing the seeds half-imbedded in their fleshy 

 fanicles, but not in pulp, as generally described. Fig. 8, a seed deprived of its fiinicle, seen on its 

 dorsal face. Fig. 9, the same, shown on its ventral face, with its central peltate hUum : all natural size. 



Plate VII. 



A. Tabemmmontana citrifolia, part of a plant. Kg. 1, a flower in bud. Fig. 2, the coroUa in bud. 



Fig. 3, the calyx. Fig. 4, the corolla after expansion. Fig. 5, the same cut open, to show the intro- 

 flexion of the segments into the mouth of the tube in aestivation, and the position of the stamens 

 always partially exserted : all natural size. Fig. 6, one of the slender stamens, always of a pale blue 

 or greenish colour, magnified. Fig. 7, the sepals, thrown back to show their inner scales, the disk 

 ovaries, style, clavuncle, and stigmata, all magnified. Fig. 8, the two divaricated follicles, "one of 

 them dehiscing, showing the position of the seeds half -immersed in fleshy funicles (after Plumier) 

 Fig. 9, a seed, seen on its dorsal face, suspended by its fleshy funicle. Fig. 10, the same, viewed 

 sideways. Fig. 11, the same, on the ventral face. Fig. 12, the seed detached, seen on its ventral 

 face, showing the central hUum, from which it is suspended. Fig. 13, the same, shown on its 

 dorsal face : all natural size. 



B. Tabemcsmontana lanceolata, a plant in flower and in fruit. Fig. 15, a flower in bud. Fig. 16 the 



coroUa expanded. Fig. 17, the same, cut open to show the position of the hal£-exserted stamens : all 

 natural size. Fig. 18, a stamen, magnified. Fig. 19, the calyx, with the sepals thrown back to show 

 the inner scales, the disk, ovaries, clavuncle, and stigmata. Fig. 20, a seed suspended by its fleshy 

 funicle. Fig. 21, the same deprived of the funicle, shown on its dorsal face. Fig. 22, the same 

 shown on its ventral face, with the central hilum : all natural size. 



Plate VIII.

 size.
