Hui_ita.—An erect, quite glabrous, suffrutescent herb, 2 to 44 ft. 
high, with the habit of some species of Hxacum, really handsome, by 
far the most robust of all tropical African Gentianez, 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 13 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 4 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 135 to 3 in., patent 
on the flowering plant ; the upper leaves linear-lanceolate or 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 134 in. long, unequal, erect-spreading, 
quadrangular, somewhat thickened towards the apex ; flowers erect, 
1 to 14 in. long; calyx glaucescent-green ; 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-celled ; 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 rocky 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. erythrzodes Hiern, sp. n. 
An annual, glaucescent-green, rather fleshy, erect herb, with 
the aspect of a Centawrium, nearly glabrous, about a foot high; 
root rather thick at the crown, decumbent, giving off 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, } to 1} in. long by + to } in.
