DESCRIPTION OF THE PLATES. 269 
B. Codonemma calycina, a portion of the plant. Fig. 1, a portion of the inflorescence. Fig. 2, a 
flower in bud. Fig. 3, the corolla in bud. Fig. 4, the same, cut open to show the simply convolute 
segments in «stivation, and the position of the stamens. Fig. 5,a stamen: magnified. Fig. 6, 
the same, with the disk, ovaries, style, clavuncle, and stigmata, natural size. Fig. 7, the tubular 
calyx cut open, showing the four series of internal scales. As I have not seen the follicle, no

showing on its ventral face the central hilum, where it is attached to the funicle. Fig. 10, the 
same, seen on its dorsal face: all natural size. 
B. Anacampta congesta, a portion of a plant in flower. Fig. 1, a flower in bud, natural size. Fig. 2,

and the position of the stamens: magnified. Fig. 4, a stamen, more magnified. Fig. 5, the calyx, 
with the sepals thrown back to show the lacinulated scales, the disk, ovaries, style, clavuncle, and 
stigmata, all magnified. Fig 6, the two divaricate immature follicles. Fig. 7, immature seeds half- 
imbedded in fleshy funicles : both natural size.

A. Rhigospira quadrangularis, portion of a plant. Fig. 1, the inflorescence. Fig. 2, a flower: both 
natural size. Fig. 3, the corolla in bud, showing the pyramidal form of the erect segments in 
wstivation. Fig. 4, the same cut open when expanded, showing their simple sinistrorse convolution 
and the nearly basal position of the stamens: both magnified. Fig. 5, the calyx, disk, very short 
style, clavuncle, and stigmata, natural size. Fig. 6, the same, magnified. Fig. 7, a stamen, much 
magnified. 
B. Stemmadenia insignis, portion of a plant in flower. Fig. 1, the calyx, with its bract, pedicel, 
and its five unequal sepals, the two exterior shorter. Fig. 2, the same, with the sepals thrown back 
to show the coronal ring of very numerous inner scales, divided disk, ovaries, style, clavuncle, and 
stigmata: both natural size. Fig. 3, the same parts, magnified. Fig. 4, the corolla cut open, showing 
the position of the stamens, natural size. Fig. 5, a stamen, magnified.

and style. Fig. 3, the corolla, with its segments retroflexed when expanded: all natural size. 
Fig. 4, the corolla in bud, the tube spirally twisted. Fig. 5, the corolla cut open, showing the in- 
flexion of two of its segments in æstivation, the others expanded, and the mm of the starmens. 
Fig. 6, the calyx, with the sepals thrown back to show the inner scales, divided disk, ovaries, and 
style: all magnified. Fig. 7, a stamen, more magnified. Fig. 8, the two follicles, 
cut away to show the placentary expansions of the sutural margins. Fig. 9, a seed s ? 
its fleshy funicle, as seen on that side. Fig. 10, the same, shown on the dorsal face. Fig. 11, the 
same with the funicle removed, showing it pluricostate on the dorsal face. Fig. 12, the same, shown 
on the ventral face with the central hilum, where it is attached to the funicle: all natural size.
