 Canthium platyphylluni : — 



16. Canthium lactescens Hiern, sp. nov. 



A very densely branched tre^, 15 to 25 ft. high ; trunk 1 to 

 1^ ft. in diameter, bifurcately branched a little above the base ; 

 branchlets rather thick, dusky-ashy, nodose, glabrous, patent ; 

 leaves opposite, broadly ovate or irregularly rotund, more or less 

 pointed or minutely apiculate or rounded at the apex, rounded or 

 obtuse to or near the base, membranous, somewhat glaucescent, 

 glabrous above, rather paler and glabrous except the tufts of 

 hairs in the axils of the (about 8) pairs of lateral veins beneath, 

 1^ to 2\ in. long by 1 to If in. broad ; petiole \tf) ^ in. long, 

 glabrous or very nearly so ; stipules interpetiolar, broadly deltoid, 

 minutely apiculate, copiously lactescent, deciduous; flowers 

 pentamerous, pale yellowish, in colour and also almost in scent 

 like elder, numerous, about ^ in. long and across, on shorter 

 pedicels, arranged in much branched puberulous axillary and 

 sub-terminal pedunculate panicles of 1 to \^ in. in diameter ; 

 peduncles \ia ^vn. long, puberulous ; caljrx-limb very small, with 

 very short teeth ; the tube very easily separable from the ovary, 

 glabrous or very nearly so ; corolla superior, glabrous or very 

 nearly so outside ; the tube short, somewhat funnel-shaped, shaggy 

 inside and at the throat ; the lobes ovate, pointed at the apex, 

 valvate in the bud, longer than the tube, spreading or recurved 

 in flower ; anthers inserted about the sinuses between the corolla- 

 lobes on very short filaments, exserted, glabrous, ovate-oblong, 

 obtuse ; style glabrous, solitary ; stigma subglobose, slight y 

 calyptriform and compressed, shortly exserted beyond the open 

 corolla but falling rather short of the anther-tips, glabrous, 

 1 0-ribbed, 5 of the ribs opposite to the anthers and the other 5 

 opposite to the corolla-lobes ; all these organs pale yellowish ; 

 ovary 2 -celled, cells uniovulate, ovules pendulous. 



HuiLLA. — In forests near Lopollo, towards the east, in company 

 with Nooha {Parinari Uohola ; Welw. herb. no. 1282) and Gigalohium 

 abyssinicum (Welw. herb. no. 1782) ; fl. end of Dec. 1859. No. 3157. 



This is nearly related to C. crassum and C umbrosum. 



LXX. DIPSACEiE. 



This family is represented by only two species, occurring on 

 the table-lands of Huilla, which in the Linnean sense belong to 

 the genus Scabiosa ; one of them in October soon after the first 

 spring rains clothes the meadows and pastures of Humpata and 

 Mumpulla with its whitish violet-tinted fiower-heads; the form 

 of it found above Mumpulla had violet-coloured flowers passing 

 into bluish, which when dried became quite white and sub- 

 sequently yellowish-white. The other species has white flowers 

 appearing very abundantly in the humid forest-meadows of
