270 DESCEIPTION OF THE PLATES. 



B. Anartia recurva, a portion of a plant, showing its heterophyllous opposite leaves and its axillary 

 inflorescence. Fig. 1, a flower in hud. Rg. 2, the corolla, with the segments expanded : both 

 natural size. Fig. 3, the corolla in hud. Fig. 4, the corolla cut open, to show the manner of the 

 inflexion of the segments when in bud, their expansion afterwards, and their dextrorse convolution and 

 the position of the stamens. Fig. 5, the pedicel and calyx, with the sepals thrown hack to show the 

 inner scales, the disk, ovaries, style, clavuncle, and stigmata : all magnified. Fig. 6, a stamen, more 

 magnified. 



Plate XII. 



A. Geissospermum Solandri, a portion of a plant in flower, showing its alternate leaves and terminal 



inflorescence. Fig. 1, one of its minute flowers, natural size. Fig. 2, the same, five times mag- 

 nified. Fig. 3, the corolla, cut open to show the dextrorse simple convolution of its segments and 

 the position of the stamens. Fig. 4, the urceolate disk with ciliolate margin, concealing two globose 

 pilose ovaries : both equally magnified. Fig. 5, an anther, more magnified. Fig. 6, the two follicles 

 of Geissospermum Vellosii, one of them dehiscing, showing five seeds in each row suspended from 

 the sutural margins by fleshy funicles. Fig, 7, a transverse section of a follicle, to show the mode 

 of placentation and attachment of the seeds. Fig. 8, a suspended seed, seen on its funicular side. 

 Fig. 9, the same, viewed from the opposite face. Fig. 10, a seed detached from the funicle on its 

 ventral side, showing the central hilum by which it is attached to the funicle. Fig. 11, the hete- 

 rotropous embryo enclosed in copious albumen. Fig. 12, the embryo extracted : all natural size. 



B. Robbia cestroides. Fig. 1, part of the plant, with its axillary inflorescence. Fig. 2, a flower: natural 



size. Fig. 3, the corolla in bud, four times magnified. Fig. 4, the same expanded. Fig. 5, the same 

 cut open, showing the dextrorse simple convolution of the segments, and the position of the stamens. 

 Fig. 6, the stamens cohering in a cone. Fig. 7, the pedicel, the calyx, with the sepals thrown back 

 to show the inner scales, the disk, ovaries, style, clavuncle, and stigmata : all equally magnified. 

 Fig. 8, a stamen seen before and behind. Fig. 9, the style, clavuncle, and stigmata : both more 

 magnified. Portion of a plant of Robbia gossipina, showing the glands on the axils of the 

 nerves and the two follicles, one of them beginning to open. Fig. 10, a seed, shown on its dorsal 

 face, covered with long while cottony hairs. Fig. 11, the same, seen on its ventral face, where it is 

 sparsely pubescent, channelled on its ventral face, with an oblong central hilum. Fig. 12, the 

 albumen extracted. Fig. 13, longitudinal section of the same, with the enclosed heterotropous 

 embryo. Fig. 14, the embryo extracted, with a superior radicle : all natural size. 



Plate XIII. 



A. Malouetia glandulifera, portion of a plant, showing the porous glands in the axils of the nerves, 



its inflorescence, and its follicles. Fig. 1, a flower in bud. Fig. 2, the corolla cut open, show- 

 ing the five acute scales in its mouth, the tube with five conspicuous nerves. Fig. 3, one of the 

 anthers more than half exserted. Fig. 4, the five anthers cohering in a cone : all natural size. 

 Fig. 5, a stamen, magnified. Fig. 6, calyx, with the sepals thrown back to show the alternate basal 

 scales, the 5-lobed disk, the ovaries, the style, clavuncle, and stigmata, magnified. Fig. 7, a seed, 

 shown on its ventral and dorsal faces, natural size. Fig. 8, the same, magnified. Fig. 9, the 

 embryoniferous albumen, extracted. Fig. 10, the embryo removed : loth equally magnified. 



B. Thyrsanthus bracteatus, a portion of the plant. Fig. 1, the panicle. Fig. 2, a flower : both natural 



size. Fig. 3, a flower. Fig. 4, the corolla cut open, showing the position of the stamens : both mag-
