Lindau’s D. kamerunensis is Passarge, 128, from the Cameroons. ‘The species of 
the present group are all of them near D. bupleuroides, and D. roxburghiana, Nees ; 
but why Dr, Thomson and Prof. Oliver thought the present plant specially near 
D. bupleuroides is not so clear; the heads have not the axillary character seen in 
D. bupleuroides ; the reduced narrow upper leaves make the inflorescence appear 
like heads in a terminal panicle.

_ Calyx tubular-campanulate, with 5 long narrow teeth. Corolla-tube 
somewhat curved, widening very gradually upwards ; lobes spreading, 
ovate, very obtuse, imbricate in the bud, one lobe entirely within, the 
two posterior somewhat united. Stamens 4, inserted on the corolla- 
tube, didynamous; anthers composed of one anther-lobe, in the bud 
folded upon the filaments, lying inside and parallel to them, acute at 
the free end and dehiscing by a short slit, which commences at the free 
end and extends towards the middle ; the second anther-lobe represented 
Sy @ minute wart at the apex of the filament. Pollen smooth, sub- 
lobose. Ovary with two unequal cells, each with 6-10 ovules in two 
rows. Capsules markedly oblique, flattened laterally, and grooved down
