opposite, lanceolate, 14-2? lin. long, acuminate, glumaceous, concave ; 
bracteoles subulate, 1-1} lin. long. Calyx 33-4 lin. long, narrow, about 
15-nerved, glabrous except for a few minute hairs on the margins of the 
teeth, rigid, 4-toothed (or sometimes with the uppermost tooth present 
but very minute) ; teeth narrowly lanceolate, 14-1} lin. long, acuminate, 
rigid. Corolla dark yellow, glabrous outside; tube 4~5 lin. long, narrow, 
slightly curved and inflated above the calyx; limb 2-lipped, both lips 
being strongly recurved in the dried state; upper lip deeply 3-lobed ; 
lateral lobes lanceolate, 2 lin. long; uppermost lobe much broader, 
shortly bifid; lower lip linear, 1-1} lin. long. Style 14 lin. long. 
Capsule narrowly oblong, about 3 lin. long—Engl. in Schlechter,

279. Root simple, remotely scaly, white. Stem very often solitary, 
quite simple, prismatic-quadrangular, very scabrid with minute ad- 
pressed hairs, about 1 ft. high, erect. Leaves opposite, linear, scarcely 
2 lin. long, quite entire, distant below, imbricate above, adpressed, acute, 
gradually attenuate at the base, very scabrid like the stem. Flowers 
axillary, solitary, sessile, flesh-coloured, twice as long as the leaves. 
Calyx tubular, erect, 5-toothed, covered with adpressed hairs ; upper- 
most tooth least, the others approximate in pairs. Corolla tubular, 
pubescent outside; tube 3 times longer than the calyx, erect, cylindric 
below, gradually dilated and recurved at the throat; limb 2-lipped, 
gaping ; upper lip obtuse, unequal on the margin ; lower lip 3-fid, with 
linear acute lobes. Ovary oblong, quite glabrous, having a nectar- 
bearing gland at the base. Style simple, as long as the stamens; stigma 
rather thick, semi-bifid.— Benth. in DC. Prodr. x. 499.

This is evidently a Striga. 
42, CYCNIOPSIS, Engl. in Engl. Jahrb. xxxvi. 233. 
Flowers as in Striga, but the ovary differs in having less thickened 
placentas, which only slightly project into the cells, the seeds are much 
fewer and very much larger.—Small perennial herbs having procum- 
bent branches with short internodes. Leaves small, opposite, almost 
sessile, sometimes secund. Flowers axillary, subsessile.
