acumen. Second. nerves slender, 7-9 pairs, gradually sepa- 
rating from midrib, then arching; tertiary distant, parallel. FI. 
small, pedicellate, in unilateral racemes; calyx pubescent. Awn 
twice the length of anther; ovary and small stylopodium puberu- 
lous; style short, glabrous, obtuse.

glabra. Folia submembranacea, elliptiea, acuminata. Fructus 
globosus (cum calyce) puberulus, calycis segmentis obtusis fere

Secondary nerves 8-10 pairs ; tertiary mostly reticulate ; blade 
9—4, petiole 4 in. long. Segments of fruiting-calyx slightly 
imbricate, not enclosing the fruit, the two outer 2-3 in. long, 
š in. broad, with 12-14 longitud. nerves, the three others rounded. 
Cotyledons fleshy, bifid to base, nearly equal. Hypocotyl nearly 
as long as embryo, pubescent excepting the tip, imbedded between 
the 4 lobes of the cotyledons, the cells of which are filled with 
starch.

Lower Cochinchina, where in one place it grows gregariously, 
covering an entire mountain-side. 
A most remarkable species, the exact position of which cannot 
be determined until the flowers are known. Segments of fruiting- 
calyx almost valvate. Fruit cylindric, black, shining. Embryo 
cylindric, slender; hypocotyl 3-sided, thickened at the apex; 
the cotyledons fleshy, 3-sided, bifid to base, the two lobes of 
one turned upwards, enclosing the hypocotyl, those of the 
other turned towards the base of the fruit. My observations 
agree with Pierre’s excellent description, except that the coty- 
ledons are chiefly filled with starch (“ contiennent beaucoup de 
matiére grasse," Pierre).
