appear to be allied to A. mavulatus, N. E. Br., diflfering in its smaller inflorescence 

 and absence of hairs inside the tube of the spathe. 



21. A. Johnsoni, N. E. Br. Tuber depressed. Leaf about 2 ft. 

 in diam., glabrous; petiole 1^-2 ft. long, smooth ; terminal segments 

 5-6 in. long, IJ-lJ in. broad, oblong, acuminate or somewhat cuspidate- 

 acuminate, cuneate and narrowly decurrent at the base. Peduncle 

 2^-3 ft. high, smooth, spotted, at least on the upper part. Spathe 

 erect ; tube convolute, 2>\-^ 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 4 J 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 l\ 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, N. E. 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, 1-1 J 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. — Hydros7ne 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 "c. fl. (with flower) Dec. 1857 and Jan. 

 1857." Schott describes the spadix as being often 2 ft. long, but on the copy of
