I have not seen this plant, the leaves of which appear to have been unknown to 
Engler, but I think it probable that specimens in leaf and fruit collected by Wel- 
witsch may belong to this species; I therefore give the following description, com- 
piled from the specimen and notes made by Welwitsch in the British Museum : 
Rhizome fleshy, with thick, fleshy, simple roots. Leaves appearing after the flowers, 
green above, glaucous-pruinose beneath, glabrous ; petiole 5—6 in. long, spotted with 
purple; blade 4-5 in. long, 23-31 in. broad at the insertion of the petiole, deltoid- 
or ovate-deltoid-sagittate, shortly and rather abruptly acuminate; basal lobes broadly 
deltoid, obtuse, with a broad triangular sinus 3-1} in. deep between them ; veins 
very conspicuous, Spathe and spadix not seen. Peduncle short. “ Berries densely 
glomerated in a shortly pedunculated head, subterranean, white, angulate-sub- 
pyriform, umbonate with the remains of the stigma, 2-celled, cells 1-seeded (Wel- 
witsch).”—Stylochiton natalensis, Engl. Aracee No. 71. S. natalense, Rendle in

‘streams between Quilanga and Catete, 2400-3800 ft., Welwitsch, 231!

Rhizome horizontal, about } in. thick, fleshy, with thick fleshy simple 
roots. Leaves 5-8 to a plant, contemporary with the flowers ; petiole 
3-6 in. long, yellowish-green spotted with purplish-violet, the sheathing 
part subterranean ; blade hastate or hastate-sagittate, as long as the 
petiole ; front lobe oblong-lanceolate, acuminate ; basal lobes somewhat 
spreading, oblong acute, about } as long as the first lobe. Spathe very 
shortly pedunculate, arising from the rootstock by the side of the 
leaves, 2 in. long ; tube subterranean, cylindric, slightly inflated at the 
base; limb ovoid, acute, with a narrow mouth on one side. Spadix 
shortly protruding from the mouth of the spathe. Female flowers 6-9 
or more (in one cycle?), adnate to the base of the spadix, connate. 
Perianth adnate to the apex of the ovary (2), with a short free oblique 
ureeolate limb. Ovary inferior (2) ; style moderately slender, much 
exserted, erect, “articulated ” (thickened) below the middle. Fruit sub- 
terranean, consisting of the connate ovaries, fleshy, included in the 
dilated base of the spathe.—Blume, Rumphia, i. 88; Kunth, Enum. iil.
