 HuiLL.v. — An erect, quite glabrous, suffrutescent herb, 2 to 4J ft. 



high, with the habit of some species of Exacum, really handsome, by 

 far the most robust of all tropical African Gentianeae, and at the same 

 time remarkable for the size and bright rosy violet colour of its 

 numerous flowers ; root perennial, rather thick, sub-fusiform, woody, 

 nearly an inch thick at the neck ; stems 2 to 5, quadrangular, acutely 

 winged at the angles, simple below to the height of 1 to 1^ ft., 

 branched above, green, not glaucous ; branches opposite, erect-patent, 

 somewhat 4-winged, the lower ones ranging up to 6 in. long ; branchlets 

 fastigiate ; leaves much acuminate ; the lower stem-leaves lanceolate, 

 2 to 3 in. long, but little more than \ in. broad in the middle, at the 

 base decurrent on both sides into a narrow wing, 3-nerved, bright 

 green, longer than or as long as the internodes of I5 to 3 in., patent 

 on the flowering plant ; the upper leaves linear-lanceolate ot linear, 

 gradually narrower and shorter, the uppermost and floral ones narrowly 

 linear, almost subulate ; panicles ample, about a foot long, 20- to 

 60-flowered ; pedicels 1 to 1^ in. long, unequal, erect-spreading, 

 quadrangular, somewhat thickened towards the apex ; flowers erect, 

 1 to \\ in. long ; caljrx glaucescent-greeu ; the segments 5, obtusely 

 but clearly keeled, membranous on the margins, linear-lanceolate, 

 subulate-acuminate at the apex with the prolonged keel far exceeding 

 the corolla-tube, rather strict ; corolla rather fleshy, becoming 

 chartaceous-rigid in the course of drying, deeply 5-lobed ; the lobes 

 broadly lanceolate, gradually acuminate at the apex, at least twice 

 as long as the calyx, tardily deciduous ; stamens 5 ; filaments short, 

 dilated-flattened at the base, inserted a little below the sinuses of the 

 corolla, declinate, anthers oblong, 2 or 3 times as long as the filaments, 

 cordate at the base, 2-celIed ; the cells longitudinally dehiscent, spirally 

 twisted ; style divergent from and longer than the stamens, at the apex 

 thickened, 2-lobed ; the lobes erect, stigmatose ; ovary rather fleshy. 

 On woody grassy rooky slopes of the loftiest ridges of the mountains 

 of Serra de Xella, not far from and below Mumpulla, at an elevation 

 of 4000 ft., in rather dry situations ; fl. June and July 1860. No. 1526. 



2. C. erythraeodes Hiern, sp. n. 



An annual, glaucesceut-green, rather fleshy, erect herb, with 

 the aspect of a Gentauriwn, nearly glabrous, about a foot high ; 

 root rather thick at the crown, decumbent, giving ofi' descending 

 fibres at its base and several erect or ascending stems at its apex ; 

 stems compressed-quadrangular, leafy at the base, simple below, 

 branched at the inflorescence, the angles narrowly winged ; radical 

 leaves rosulate, obovate-spathulate, -J to 14 in. long by |- to -i in.
