rotuudis, mediano duplo latiore ; antherarum parte inferiore cal- 

 carato emarginato. 



Hab. West of River Shebele, Dec. 3rd, 1894. 



A small low-growing shrub about 12 cm. above ground. The 

 strong rootstock breaks up into stout branches, which from a little 

 above the base bear opposite branches, these again branching. 

 The older internodes are divided by narrow longitudinal furrows 

 into white linear strips. Petioles about 1-2 mm. long ; leaves 

 8-15 mm. long by 5-8 mm. broad. Flowers 2-3 together, forming 

 a reduced inflorescence in the leaf-axils. Bracteoles 1 mm. long. 

 Calyx-segments 5-5-5 mm. long by 5 mm. broad at the base. Corolla 

 slightly pubescent on the outside ; tube 3 mm. long, 2-3 mm. broad, 

 1*5 mm. at the mouth ; anterior lip 5 by 4 mm. ; posterior 6 mm. 

 long, centre lobe 3 by 3 mm., lateral lobes 3 by 1"5 mm. Filaments 

 8 mm. long, anthers 1 mm. ; spur -5 mm. broad. Ovary oblong, 

 pointed, 2 mm. long, girt by an annular disc -4 mm. higli ; style 

 slender, 5 mm. long, apex notched.

Hab. Darar, Sept. 12th, 1894. 



A low erect shrub with spreading ascending branches, scarcely 

 3 dm. high, the stem terete, 3 mm. in diameter at the base, the 

 branches tapering to about 1 mm. in the upper internodes. Like 

 the leaves, bracts, and bracteoles, the younger parts of the 

 branches are densely covered with the short stiff pointed generally 

 upwardly directed hairs. The slender leaf-stalks are about 3 mm. 

 long, the leaves 2-2-5 cm. long by 8-10 mm. broad. The bracts 

 in the lower part of the spike reach 12-15 cm. long by 4 broad, the 

 bracteoles are 5-8 mm. by scarcely 1 mm. The sepals are 

 6-6-5 mm. long, increasing in the fruiting stage, the short calyx- 

 cup, and the lower part of the segments bear on the outside short 

 capitate glandular hairs ; the upper part of the segments is densely 

 covered with the characteristic setulae. The corolla-tube is 6 mm. 

 long, 1-5 mm. in diameter at the base, 2 mm. at the waist, 

 widening gradually to 3 mm. at the mouth. The upper lip is 

 6mm. long, 5 mm. broad at its base; the lower is 7*5 mm. long by 

 6 mm. broad just below the rounded lobes, of which the slightly 

 larger median is 1*5 mm. long by scarcely 2.5 mm. broad ; the top 

 is flat in the upper part, but the disc is raised into a pair of median 

 convex crests. In the dried plant the stamens hang out one each 

 side of the flower. The filament is 5 mm. long, the anther and the 

 sharply pointed curving spur of the lower cell are each about
