appear to be allied to A. maculatus, N. E. Br., differing in its smaller inflorescence 
and absence of hairs inside the tube of the spathe. 
21, A. Johnsoni, V. /. Br. Tuber depressed. Leaf about 2 ft. 
in diam., glabrous; petiole 14-2 ft. long, smooth; terminal segments 
5-6 in. long, 14-1} in. broad, oblong, acuminate or somewhat cuspidate- 
acuminate, cuneate and narrowly decurrent at the base. Peduncle 
21-3 ft. high, smooth, spotted, at least on the upper part. Spathe 
erect ; tube convolute, 34-4 in. long, about 3 in. diam., urceolate or 
pear-shaped, distinctly constricted just below the mouth, tapering to 
the base, pale green, spotted with darker green on the lower part, passing 
into deep reddish or brownish-purple on the upper part outside, inside 
the tube is whitish and densely covered with short soft bristle-like 
processes or very stout hairs on the basal part ; limb about 44 in. long, 
broadly ovate, obtusely pointed, oblique or somewhat spreading, 
entirely dark brownish-purple on both sides, the colour abruptly 
changing to white inside at the constriction of the tube. Spadix 
longer than the spathe, sessile; female part in the dried state about 
1 in. long, cylindric ; male about 14 in. long, slightly obconic ; appendix 
about 9 in. long, 13-14 lin. thick in the lower part, gradually tapering 
to an obtuse point, smooth, very dark purple-brown. Ovaries de- 
pressed globose; stigma subsessile, with 2 large lobes. Anthers 
densely crowded.

22. A. angolensis, V. #. Br. Leaf 2 ft. or more in diam., 
glabrous ; petiole 3—5 ft. long, smooth, spotted with red at the base; 
terminal segments 4—6 in. long, 1-14 in. broad, the others smaller, 
oblong-lanceolate or elliptic-oblong, somewhat abruptly acuminate, 
decurrent at the base. ‘ Peduncle by the side of the leaf, variegated 
with green and purple” (Welwitsch), 10-12 in. long in the specimens 
seen, probably longer, smooth. Spathe 11-12 in. long, cucullate, 
shorter than the spadix, spreading, subacuminate, wavy on the margin, 
hairy at the base inside. Spadix very long; flowering part dense, 
cylindric, female about 2 in. long, male about 1 in. long; appendix 
long, terete, obtuse, naked, blackish-purple. Ovary oblong-ovoid ; 
stigma sessile, 2-lobed. Pollen orange-coloured.—Hydrosme angolensis,

According to Welwitsch’s notes this would appear to produce its flower and leaf 
at the same time, since, besides stating that the peduncle is by the s'de of the leaf, 
he adds at the foot of the label of No. 228 “ce. fl. (with flower) Dec. 1857 and Jan. 
1857.” Schott describes the spadix as being often 2 ft. long, but on the copy of
