early arrival of the spring rains ; thatis to say, the sooner in September 
the plant appears, the sooner are the first rains expected.

2. A. Welwitschii Rendle sp. nov. Habit and foliage very 
similar to that of the last species; petiole and rachis of leaf- 
segments aculeate, ultimate leaf-segments unequally rhomboidal, 
bipartite, peduncle sparsely aculeate ; spathe lanceolate in outline, 
straight, hooded at the apex, sulphur-yellowish, spotted with red in 
the inside at the base, spadix more than half the length, whitish, the 
female portion half the length of the male ; ovaries smooth, greenish, 
apex rhomboid-elliptical, somewhat flattened, stigma excentric and 
shallowly conical, almost umbonate, with a depressed apex. 
Peduncle 9 to 18 in. long by 2 to 22 lines thick when dried. 
Spathe 6 in. long by about 14 in. greatest diameter; spadix 
about 3 in. long, female portion 2 in. thick, male 4 in. thick 
at the base, tapering gradually towards the apex. Ovary with 
stigma 2 lines long. 
Resembles in habit both the hitherto known West African 
species, but is distinguished from A. Hookeri by its smooth ovaries 
and yellow colour of spathe, while A. dudius differs in its much 
larger purplish or white spathe, and narrow conical style.

of Jan. 1855, No. 220°. This Aroid is cultivated singly here and

of its edible tuber.
