7. I. coscinosperma, Hochst. ex Choisy in DC. Prodr. ix. 354, 

 partly. Annual. Stems trailing, slightly hairy. Leaves linear- 

 lanceolate or oblong danceolate, 1^-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 3 lin. 

 long ; sepals lanceolate, glabrous but margin of the outer sepals often 

 ciliate, abruptly acuminate from an ovate base in the fruit. Corolla red, 

 slightly longer than the calyx, up to 4 lin. long. Capsule globose, glabrous 

 3 lin. in diam. Seeds punctate. — Hallier f. in Engl. Jahrb. xviii. 124.

Var. glabra, Schimper in Herb. PL Abyss. 2323. — Stem and leaves nearly or

 generally narrower. Sepals glabrous or sometimes with bristly ciliate margins. — I.

Schweinfurth separates this specifiially on account of the ciliated sepals, but this 

 character is a very variable one in this alliance ; of the two specimens, otherwise 

 similar, which represent Schimper's collecting, No. 2323 in the British Museum set, 

 one has tbe sepals quite glabious, the other strongly ciliate. It was on tliis collect- 

 ing that Schweinfurth' s species was based. Kotschy's 376 has the sepals quite 

 glabrous, as is also the rest of the plant.
