25. Buchnera linearifolia, Schumach. &• Thonn. Beskr. Guin. PL 

 270. Root simple, remotely scaly, white. Stem very often solitary, 

 quite simple, prismatic-quadrangular, very scabricl with minute ad- 

 pressed hairs, about 1 ft. high, erect. Leaves opposite, linear, scarcely 

 Jf 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. Proclr. 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 secuncl. Flowers axillary, subsessile.
