River Cuanza, near Nbilla, Welwitsch, 6642. 
Mozamb. Dist. Lake Tanganyika, Cameron? 
Also from Madagascar. 
This almost surely belongs to the present group. There were 4 seeds in the two 
ventral cells ; the dorsal cell in the one capsule preserved is empty, as happens occa- 
sionally. 
4, ©. Gambiz, (. 2B. Clarke in DC. Monogr. Phan. iii. 146. Thinly 
villous. Stems 20 in. long, much divided ; base decumbent, rooting at 
the nodes; roots fibrous. Leaves 2-3 by } in., linear. Spathes on 
peduncles exserted (—} in., numerous, solitary, 3 in. long, simply folded, 
ovate, shortly acuminate, rounded or rhomboid at the base. Flowers 
small, deep blue. Capsule usually 5-seeded; seeds of the ventral cells 
searcely ;, in. long, subglobose, strongly reticulated, the margins of the 
reticulations much raised, continuous.—Durand & Schinz, Conspect. FI.

This is the plant “ indicated” by Bentham (in Hook. Niger Fl. 542) as C. Fors- 
kalzi from Senegambia. The leaves and spathes resemble fairly well those of 
C. Forskala@i, Vahl; but the capsules and seeds are totally unlike. 
5. C. scaposa, C. B. Clarke in Comptes-rendus Soc. bot. Belg. xxxviii- 
220. Nearly glabrous. Leaves on sterile stem not seen. Fertile stems 
8-12 in. long, simple, leafless, with 2 or 3 distant leaf-sheaths ; free 
point to the leaf-sheaths less than } in. long. Spathes solitary, on 
peduncles up to 2} in. long, simply folded, the margins hardly united at 
the base, $—2 in. long, ovate, shortly acuminate. Seeds normally 5 to 
the capsule, those in the ventral cells slightly pitted and tubercular.

6. C. subulata, Roth, Vov. Pi. Sp. 23. A nearly glabrous annual. 
Stems 6-15 in. long, weak, divided. Leaves 2 by 4-} in., linear. 
Spathes scattered, solitary, on a peduncle hardly exserted from the 
leaf-sheath, 4 in. long, ovate, shortly acute, simply folded, not striated 
by curved coloured parallel lines ; inflorescence little exserted from the 
spathe. Petals small, blue (see note below). Capsule 3-1 in, long, 
with normally 5 seeds. Seeds of the ventral cells (often strongly} 
wrinkled, as well as pitted subtuberculate.—C. B. Clarke in DC. Monogr.
