Central Africa. Stated to have been imported from the "ueighbourhood of 

 Lake Nyaiiza " (Lake Nyasa ?), cultivated specimen ! 



Also in South Africa. 



The differences of the overlapping basal lobes of the leaf, and the presence of 

 bristles on the petiole, by which I originally distinguished R. Lutwychei from 

 i2. hastata, I find to be inconstant; with regard to the bristles on the petioles of 

 B,. hastata they are either sometimes absent, or disappear in the process of drying. 



4. R. angustiloba, Schott in Journ. Bot. 1865, 35. Leaves gla- 

 brous; petiole smooth, without bristles ; blade 7^-17 in. long, 4-1 1 in. 

 broad across the basal lobes, hastate, green, without spots ; the part 

 above the basal lobes elongate-deltoid or elongate-oblong, often very 

 narrow, acute or acuminate, 2-5 times as long as broad ; basal lobes 

 very variable, short or long, sometimes very spreading, sinus very open. 

 Peduncle about as long as the leaves, smooth. Spathe 4-4 J in. long, 

 clear deep gamboge-yellow, with a dark purple-brown blotch at the 

 base inside, "intense sulphur-coloured, blood-red at the base inside" 

 (Wehoitsch), paler outside; tube funnel-shaped; limb oblique, sub- 

 horizontal, acute. Spadix shortly stipitate, scarcely half as long as the 

 spathe, cylindric, obtuse. Ovary subglobose, pale greenish-white ; style 

 short; stigma small, discoid. Staminodes none. Anthers yellow. 

 Berries large, subglobose or obovoid. — Engl, in DC. Monogi-. Phan. ii.

Iiower Guinea. Angola : Pungo Andongo ; frequent in deep stngnant places 

 between the islands Calemba and Quisonde, on tiie right bank of the River Cuanza, 

 2040-3800 ft., Welwitsch, 230 ! 1020 (ex Rendle) ; Huilla ; near Lopollo, frequent 

 in swamps near rivers, 5000 ft., Welwitsch, 232 ! 232/2 ! in spongy places at the 

 great lake of Ivantala, Wehvitsch, 232/3 ! 



R. nilotlca, mentioned by W. Wats, in Garden ar.d Forest, 1892, 618, wiih 

 white and red spathes, and said to hnve been "collected on the banks of the Nile " is 

 probably jB. Rehmanni, N. E. Br., a native of Natal, but which, probably, also grows 

 in the Transvaal, and perhaps the " banks of the Nile" may be a misinterpretation of 

 Nylstroom or Nyl River in the Transvaal.

Spathe expanded, not convolute, decurrent on the peduncle at the 

 base, persistent. Spadix free, monoecious, shorter than the spathe, with- 

 out an appendix or neuter organs ; male and female parts contiguous. 

 Perianth none. Ovaries crowded, 1-celled ; stigma sessile, discoid or
