lanceolate or oblong-lanceolate, 14-2} in. long, entire, subobtuse, 
narrowed gradually to the base, sparsely hairy, chiefly on the nerves; 
petiole up to 6 lin. long. Flowers 1-2 in the axils of the leaves on very 
short pedicels. Bracts small, linear, tapering, 2 lin.long. Calyx 8 lin. 
long ; sepals lanceolate, glabrous but margin of the outer sepals often 
ciliate, abruptly acuminate from an ovate base in the fruit. Corolla red,

Schweinfurth separates this specifically on account of the ciliated sepals, but this 
character is a very variable one in this alliance; of the two specimens, otherwis? 
similar, which represent Schimper’s collecting, No. 2323 in the British Museum set, 
one has the sepals quite glabrous, the other strongly ciliate. It was on this collect- 
ing that Schweinfurth’s species was based. Kotschy’s 376 has the sepals quite 
glabrous,-as is also the rest of the plant.
