Lower Guinea. Angola; swamp near Kitamba, Buchner, 578; Pungo 
Andongo ; Sansamanda, Welwitsch, 6195! Luxillo, Welwitsch, 6223 ! 
Hallier has identified the Welwitsch numbers at the British Museum with his 
I hewittioides, which differs (from the description) in having a very short subterminal 
peduncle (axillary in the penultimate leaf-axil) ; in the Welwitsch plants peduncles 
are present in most of the leaf-axils, and are generally long. We are unable to 
follow Hallier’s more recent placing of the species as a variety of J. crassipes, from 
which it seems very distinct ; it is more nearly allied to J. fulvicaulis both in 
leaf-form and in the dense several-flowered inflorescence. 
26. I. Scotelli, Rendle in Jowrn. Bot. 1901, 18. A low-growing, 
perennial undershrub; shoots 2-4 in. long, slender, spreading 
flexuously from a stout woody rootstock, and, like the petioles, densely 
covered with short stiffish spreading yellow-brown hairs. J.eaves 
truncate-cordate, 1-14 in. long and generally as broad, apex rounded or 
scmetimes emarginate, densely covered on both surfaces, especially on 
the veins, with short stiftish adpressed hairs ; petioles $ to barely 1 in. 
long. Flowers in axillary sessile dichasia, buds bluntly conical ; 
bracteoles narrowly linear-lanceolate, barely 3 lin. long, hairy on the 
back like the leaves and sepals ; pedicels 2 lin. long or shorter. Calyx 
5) lin. long; sepals densely minutely hirsute, the outer elliptic-subacute, 
2 lin. broad, the inner linear-acute, less than } lin. broad. Corolla 
purple, tubular-infundibuliform, barely 1 in. long; tube barely 1 lin. 
in diam. above the base; midpetaline areas minutely hirsute, con- 
spicuously trinerved. Fruit not seen.
