Also in Madagascar. 
Var. major, Rendle in Journ. Bot. 1917 ined. Of similar habit to the branched 
forms of the species but on a much larger scale. The erect stems rise from the 
creeping profusely rooting base to a height of 15-16 in., and are 1} lin. thick; the 
long internodes are 23-54 in. long, the elongated branches are suberect. Leaves 
on the main strong stems 13-2} in. long, 1-2 in. wide, smaller on the branches and 
weak stems ; the stronger stems may bear leaves as large as those of the apical 
pseudo-whorl on the next two or sometimes three lower nodes. Inflorescences 
1-1} in. long.

4. P. angolensis, Rendle. A small delicate annual herb, intensely 
green, glabrous. Stem erect, fleshy, 4-9 or sometimes 12 in. high, 
simple or branched. Leaves at the upper nodes larger than those 
below, those at the lowermost nodes caducous, those of a pair sub- 
equal or unequal, ovate, obtuse, base broadly wedge-shaped to trun- 
cate, 3-nerved, the lateral nerves extending beyond the middle, margin 
dentate above the base, those of the lowest pair sometimes entire, 
3-1} in. long, 4-1} in. wide, of the lowest pair } in. long or less ; 
thinly membranous when dry, the surface often marked with linear 
slightly curved cystoliths ; petioles slender, up to 2 in. long. Sti- 
pules caducous. Inflorescence 1-sexual or 2-sexual, one to several 
m the leaf-axils, much shorter than the petioles, rarely exceeding 
3 in., generally less ; flowers in dense secund cymules on the main 
axis or its short branches; peduncle short, slender; inflorescence 
Sometimes reduced, becoming subsessile and capituliform. Male 
inflorescence shorter than the female. Male perianth 4-partite, $ lin. 
in diam. before opening, lobes broad, blunt, with a short green sub- 
apical appendage. Female more numerous and more densely crowded 
than the male ; perianth 3-lobed, median segment hooded, blunt, 
obscurely keeled, 2-3 times as long as the two lanceolate lateral 
Segments, segments persistent in fruit, the median a little shorter 
than the achene; stigma lateral beneath the apex. Achene pale 
brown when ripe, compressed ovate-lanceolate, margin flattened, 
t lin. long.—Adicea tetraphyllg, var. angolensis, Hiern in Cat. Afr.

The reference in Hiern’s description to rigid long sete sometimes present on 
the upper part of the stem and the lower face of the leaves, evidently relates to

tudinal lines, somewhat reddish when dry and marked with short
