Fig. 7, transverse section of a fruit. Fig. 8, seed, seen front and sideways. Fig. 9, the 
same, seen from the base, to show the hilar chink : all nat. size. 
F. Discaria articulata. 
This plant, by mistake, is described in p. 289, under the name of Eetamilia articidata, 
the error not being detected till after it was sent to press : it ought to follow the enumera- 
tion in p. 279. — Fig. 1, a flower cut open, magnified. Fig. 2, a petal and stamen seen 
in front. Fig. 3, a petal seen sideways and in front. Fig. 4, a stamen seen sideways. 
Fig. 5, the same after dehiscence ; all more magnified. 
Plate 40. — A. Trevoa trinervis. 
Fig. 1, a flower, magnified. Fig. 2, the same, with half the calyx cut away, to show 
the enclosed pistil, and the position of the petals and stamens. Fig. 3, petal and stamen, 
seen in front. Fig. 4, a side view of the same. Fig. 5, a stamen seen in three different 
positions. Fig. 6, a front and side view of the same, after dehiscence. Fig. 7, a longitu- 
dinal section of the pistil : all more or less magnified. Fig. 8, a ripe drupe, nat. size. 
Fig. 9, a transverse section of the same, showing two cells. Fig. 10, a seed : all nat. size. 
Fig. 11, the same, front view, magnified. Fig. 12, a side view of the same. Fig. 13, 
basal view of the same, showing its hilar chink. Fig. 14, the same, with half of the crus- 
taceous outer integument removed, to show the second integument. Fig. 15, the same, 
with half the second tunic removed, to show the third integument or tegmetf, its apical 
chalaza, and basal constriction. Fig. 16, the peripheral cord of the raphe removed from 
the second fleshy integument. Fig. 17, the tegmen removed. Fig. 18, the albumen.

showing the line of circumscission round the base of the calyx, with the included pistil, 
and the position of the petals and stamens : both magnified. Fig. 4, a petal and included 
stamen, front and side view. Fig. 5, stamen before dehiscence, side and front view.
