they at length open, the leaf always remains somewhat canaliculate : below it is whitishly 
furfuraceous, being covered with a tomentous down, that is almost wholly concealed by a 
number of closely imbricate peltate scales with radiate ribs, which under a lens appear 
like fish-scales: the petiole is short, white, and also lepidote. The flowers often axillary, 
sometimes terminal, are altogether covered with imbricate scales ; the peduncles, one-fourth 
to three-eighths of an inch in length, are usually solitary, but sometimes in pairs. The 
. sepals are rounded, very deeply concave, the margins being very slightly imbricate before 
expansion; they are at first reflexed, and soon break off transversely along the margin of 
the torus; they are covered within by tomentous whitish hairs, and are lepidote outside. 
The torus is a fleshy deep oval cup, which after the fall of the flower becomes hardened, 
and. exhibits a somewhat bifid, erect tooth on its posterior or upper margin, and two other 
smaller opposite teeth on its sides. The six petals arise in a single whorl from the inner 
margin of the calycine cup, and are linear, and somewhat spathulate, being hairy within, 
and covered on the outside with lepidote scales: four of these are of equal length, and 
situated in pairs, opposite the sepals, while the two intermediate shorter petals are lateral, 
and alternate with the two sepals; in æstivation, the margins of the summits are some- 
what imbricately disposed, those of the shorter pair being exterior to the others; after ex- 
pansion they are all thrown back, the upper pair remaining more erect. There are six 
fertile and three sterile stamens, all seated.upon a small gibbous ring, just above the gla- 
brous thickened base of the thecaphore; the sterile filaments are shorter than the others, 
one of them being opposite to the upper petals, and the other two opposite to the lateral 
petals, two fertile stamens interposing between them; the fertile filaments are as long as 
the petals, and though somewhat plicated before expansion, are afterwards erect, and de- 
flected outwards near the summit; they are quite glabrous, with a roundish fleshy gland 
at the base, which is covered with whitish pubescence, and a few lepidote scales; these 
glands being seated upon the gibbous ring before mentioned, make it almost appear as if 
the stamens were monadelphous, but they are in reality free to the base. The anthers, 
which are oblong and basifixed on the apex of the filaments, are coriaceous, 2-celled, burst 
inwardly by longitudinal furrows somewhat in front, and afterwards curl downwards in an 
annular form. The thecaphore arises somewhat laterally from the bottom of the hollow 
cup-shaped gibbous torus, and is inclined upon its shorter side; the lower part, which is 
glabrous, rises to the height of the cup, forming the staminiferous support above men- 
. tioned, one side of this support adhering to the lower and shorter portion of the cup, the 
opposite side being free and channeled almost to its axis; above this level the thecaphore 
becomes more slender, is again inclined further downwards, and rising to the height of 
the stamens bears upon its summit the ovarium, which, with the slender portion of the 
thecaphore, is densely lepidote. The ovarium is of an oval form, somewhat nodding; the 
style is very short, and the stigma is almost obsoletely 2-lipped. The fruit is a somewhat 
fleshy berry, covered with lepidote scales, about 3 lines long and 2 lines in diameter; it is 
unilocular, bearing generally two seeds, which almost fill the cavity; the epicarp is thin’ 
and somewhat coriaceous, and separable by pressure into four equal segments, leaving the 
seeds, and the small quantity of enveloping pulp, contained within four slender cartilagi- 
nous ribs, which arise from the base of the cell and unite in the apex; these ribs corre-
