THE FLORA OF SOUTH AMERICA. 507 
fleshy, and covered on both sides with dense, short, dark grey 
tomentum : they are about 8 lines long, and barely a line in 
width: they are attached to the stem by a small glabrous 
pulvinate gland : the peduncle is slender, half an inch long; 
the calyx is 2 lines long, cleft nearly to the base, with narrow 
linear segments tapering upwards, it is tomentous both 
within and without. "The corolla is barely half an inch long, 
slender within the calyx, it swells above in a somewhat 
campanular form, is of a pale lilac colour, somewhat fleshy, 
and slightly pubescent outside; the border is narrow, and 
divided to its base into 5 short, rounded, reflected lobes, 
having at the apex a minute toothlet: the stamens are 
wholly included, and are somewhat unequal in length, the 
filaments slender, tapering, and glabrous, arise out of dense 
hairy tufts in the base of the corolla. "The disc is distinctly 
stipitate, cup-shaped, and quite free both from the corolla 
and calyx, its border nearly erect, is formed of 5 confluent 
lobes, with a margin divided into 10 distinct crenatures ; the 
gynobase arises in a conical form within the centre of this 
cup, the intermediate cavity being filled by the carpels which 
are arranged in 2 series, and are attached by a ventral, and 
almost basal point to the gynobase: from the centre of this 
arises the style, which is columnar, 5-grooved, glabrous, and 
surmounted by a 5-lobed, hollow, clavate stigma. The 
drupes are small and fleshy, enclosing an ovoid rounded nut, 
which is of a more woody texture than most of its congeners: 
this is usually 1-celled, sometimes 2-celled, the base of each 
cell being marked by an areolar cicatrix, which is partly 
hollow, the bottom of the cavity being filled up by the stro- 
phiole-like process that remains attached to the testa of the 
ineluded seed. The testa, smooth, somewhat membrana- 
ceous, and of reticular texture, encloses the albumen, which 
is fleshy, and not very copious: in this is imbedded the fili- 
form embryo, whose semiterete cotyledons are bent round in 
a nearly circular form, while the terete radicle, which is. -only 
slightly curved, and somewhat thickened towards its extre-
