length, variegated on the sheath with irregular transverse bars; blade: 
sagittate or sagittate-hastate ; front lobe 4—6 in. long, 1-1} in. broad, 
dilating where it joins the basal lobes, narrowly oblong or strap-shaped,

oblong or strap-shaped, obtuse. Peduncle 2~24 in. long, moderately 
stout, glabrous, axillary, 2 from the same axil in the specimen seen, 
accompanied by a membranous linear-oblong subacute bract about 
1? in. long. Spathe not subterranean, glabrous; tube 14 in. long, 
inflated at the base; limb about 24 in. long, expanded, oblong-lanceo- 
late. Spadix 3 in. long, curving forwards at the apex. Female 
flowers about 10 in two series, free; perianth 2 lin. long, obliquely 
ovoid-urceolate, mouth obliquely truncate; ovary free, obliquely ovoid, 
narrowed into an erect exserted style 14 lin. long, thickened or jointed 
a little below the very oblique ovate stigma. Male spike about } in. 
distant from the female flowers, not very dense; basal part laxly 
covered with abortive flowers, in which both stamens and ovary are 
rudimentary and enclosed in a subglobose-urceolate perianth. Perianth 
of perfect male flowers about % lin. deep, subcampanulate, 4—5-lobed to: 
half-way down ; lobes narrow, acute or subacute, spreading. Stamens: 
4; filaments 3-1 lin. long, clavate, exserted ; anthers oblong, basifixed 
or subadnate,

This species is allied to S. natalensis, Schott, but is readily distinguished by the- 
narrower and longer lobes of the leaf, and fewer series of female flowers. 
7. S. borumensis, V. HZ. Br. Rhizome thick, fleshy, nodose, with 
thick fleshy simple roots. Leaves appearing after the flowers, 
glabrous: petiole 4—7 in. long; blade sagittate or sagittate-hastate ; 
front lobe 24-6 in. long, 3-13 in. broad, elongate-oblong acute; basal 
lobes 1-23 in. long, 4-9 lin. broad, elongate-deltoid or deltoid-lanceolate, 
obtuse. Peduncle 14-13 in. long, glabrous, surrounded by 2-3 mem- 
branous bracts 1-11in.long. Spathe partly subterranean (?), glabrous ; 
tube 14-1? in. long, cylindric, slightly inflated at the base; limb or 
mouth very oblique, 6-8 lin. long, acute. Spadix 1-1} in. long, reaching 
to about the mouth of the tube. Female flowers 10-12, irregularly 
bicyclic, free, those of the upper cycle mostly imperfect; perianth 
about $ lin, deep, compressed or globose-polygonal, very much contracted’ 
at the mouth, somewhat oblique. Ovary free, shortly ovoid, laterally 
compressed ; style } lin. long, subhorizontally spreading, stout, shortly 
exserted beyond the perianth ; stigma large, discoid. Male spike about 
1 lin. distant from the female flowers, dense; perianth cupular, trun- 
cate, 1-1 lin. deep; stamens 4; filaments } lin. long, clavate, very 
stout ; anther-cells slightly divergent.

This species is remarkable for the very thick clavate filaments of the stamens. 
8. S. angolensis, Lngl. in Engl. Jahrb. xv.465. Leaves appearing 
after the flowers. Peduncle 1 in. long, surrounded by 4 membranous.
