Central Africa. Stated to have been imported from the “neighbourhood of 
Lake Nyanza” (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 
R. hastata, I tind to be inconstant; with regard to the bristles on the petioles of. 
R. hastata they are either sometimes absent, or disappear in the proccss of drying. 
4. R. angustiloba, Schott in Journ. Bot. 1865, 35. Leaves gla- 
brous ; petiole smooth, without bristles ; blade 74-17 in. long, 4-11 in. 
broad across the basal lobes, hastate, green, without spots; the part 
above the basal lobes elongate-deltoid or elongate-oblong, often very 
harrow, 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 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 ” 
(Welwitsch), palet 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. Monogr. Phan. ii.

R. nilotica, mentioned by W. Wats. in Garden and Forest, 1892, 618, with 
white and red spathes, and said to have been “collected on the banks of the Nile ” is 
probably R. Rehmanni, N. E. Br., a native of Natal, but which, probably, also grows. 
in the Transvaal, and perhaps the “ banks of the Nile * may bea misinterpretation of 
Nylstroom or Nyl River in the Transvaal.

Spathe expanded, not convolute, decurrent on the peduncle at the: 
base, persistent. Spadix free, monecious, 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
