 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. Kg. 2, 



the coroUa in bud. Kg. 3, the same cut open, showing the segments introflexed as in Bonafousia, 

 and the position of the stamens : magnified. Kg. 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. Kg 6, the two divaricate immature follicles. Kg. 7, immature seeds half- 

 imbedded in fleshy -funicles : both natural size. 



Plate X. 



A. Rhigospira quadrangularis, portion of a plant. Fig. 1, the inflorescence. Fig. 2, a flower : both 



natural size. Kg. 3, the corolla in bud, showing the pyramidal form of the erect segments in 

 sestivation. Kg. 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. Kg. 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. Kg. 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. Kg. 4, the corolla cut open, showing 

 the position of the stamens, natural size. Fig. 5, a stamen, magnified. 



Plate XI.

 and style. Kg. 3, the coroUa, with its segments retroflexed when expanded : all natural size. 

 Kg. 4, the corolla in bud, the tube spirally twisted. Kg. 5, the corolla cut open, showing the in- 

 flexion of two of its segments in aestivation, the others expanded, and the position of the stamens. 

 Fig. 6, the calyx, with the sepals thrown back to show the inner scales, divided disk, ovaries, and 

 style : all magnified. Kg. 7, a stamen, more magnified. Fig. 8, the two follicles, one of them half 

 cut away to show the placentary expansions of the sutural margins. Fig. 9, a seed suspended by 

 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.
