 1.!)8. Nearly glabrous, except the spathes. Stems 15 in. long, divided, 

 with very long internodes, the base not well shown in the specimens, 

 but similar to that of C. jyurjyurea. Leaves up to 7 by^-— J in., elongate, 

 linear-lanceolate. Peduncles i-2 in. long, scattered, Spathes f-1 in. 

 long, very broadly ovate, shortly acuminate, not striate with coloured 

 veins, shaggy or nearly glabrate ; the two margins of the spathe shortly 

 connate at the base. Capsule normally 5-seeded, but the ventral cells 

 contain sometimes 1 seed only (the lower ovule having proved infertile); 

 seeds subglobose, smooth. — Durand tfc Schinz, Conspect. Fl. Afr. v. 42H ;

 Pluk. cited. A diffuse, more or less hairy annual, rooting at the base, 

 1 -2 J ft. long, much branched. Near the base are often present branches 

 that grow underground, or stolons, on which reduced leaves and spathes, 

 with apetalous often closed flowers, and abnormal usually 1-2-seeded 

 capsules are formed plentifully — even where the perfect regular cap- 

 sules are also present on the upper branches. Leaves 1-3 J in. long, 

 ovate-elliptic, shortly triangular or subobtuse at the tip, suddenly nar- 

 rowed at the base into a quasi-petiole. Spathes on peduncles hardly 

 exserted from the leaf-sheaths, often a few near together near the tips 

 of the branches, J-§ in. long and broad, obliquely funnel-shaped, i.e., 

 the lower margins of the spathe connate for \-\ in. Petals blue. Cap- 

 sule 4 in. long, 5-seeded ; seeds rough or wrinkled. — Forskh. Fl. ^gypt.-
