270 DESCRIPTION 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 bud. Fig. 2, the corolla, with the segments expanded: both 
natural size. Fig. 3, the corolla in bud. 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 back to show the 
inner scales, the disk, ovaries, style, clavuncle, and stigmata: all magnified. Fig. 6, a stamen, more 
magnified. 
Puate 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. 8, 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: ail natural size. 
Prate 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 : both 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-
