230 XCVIII. ACANTHACEE (CLARKE). [ Zsoglossa. 
Nile Land. British East Africa: Leikipia, 6500 ft., HgAnel. 
There is not one word of description given to this variety by Schweinfurth. 
4, I, membranacea, (. B. Clarke. Leaves 7 by 2} in., much 
tapering at either end, membranous; petiole 1-24 in. long. Calyx 
+ in. long; otherwise as J. lawa. 
Mozamb. Dist. British Central Africa: Nyasaland ; Masuka Plateau, 6500- 
7000 ft., Whyte ! 
The calyx is about half the length of J. Jawa, the corolla is somewhat smaller. 
The large very tnin leaves may be due principally to a shady moist habitat. 
5. I. lactea, Lindau in Engl. Jahrb. xx. 55. Leaves up to 4 by 
13 in., ovate, narrowed at either end, nearly glabrous; petiole up to 
14 in. long. Peduncles axillary and subterminal, slender, bearing @ 
lax nearly glabrous panicle 1-3 in. long; bracts 3, in. long, linear. 
Calyx }-4 in. long, divided nearly to the base; segments linear, sub- 
equal, minutely scabrous-hairy. Corolla exceeding }4 in. long, cream- 
white (or violet in the form J. violacea), nearly glabrous; tube shorter than 
the lips. Filaments glabrous, or in Lindau’s figure ciliate on one side ; 
anther-cells muticous, one below the other; pollen lenticular, with one 
stopple on each face. Pistil glabrous. Capsule } in. long, stalked, 4 
seeded ; seeds tubercular-scabrous.—Lindau in Engl. & Prantl, Pflan- 
zenfam. iv. 3 B. 344, fig. 107, B, and in Engl. Pf. Ost-Afr. C. 372.

Lindau says the corolla-tube in I. violacea is only #5 in. long ; it appears to me 
scarcely shorter than in I. lactea. Scott-Elliot’s 7664 has a few scattered hairs on 
the upper surface of the leaves.

elliptic, acuminate at either end, glabrous. Flowers laxly panicled, 
clear rose colour; bracts very small. Calyx 3 in. long, finely hairy. 
Corolla-tube morejthan } in. long ; lips 2 in. long, rather broad. Capsule 
3 in. long, 4-seeded ; otherwise as J. Jactea.—Lindau in Engl. & Prantl,
