Robust, erect,, sligtly branched, about 60 cm. high, the stems terete, 
scabrid, the older ones reddish brown, the younger ■ parts rather densely 
clothed with long brittle white hairs. Leaves elliptical-ovate 2 to 3 cm. 
long, 1 to 1.5 cm. wide, those on the older parts opposite, those on the 
younger branches in whorls of four,' crowded, rigid, coriaceous, scabrid, 
sessile or short-petioled, the base rounded, the apex acute, the margins 
strongly acuminate-denticulate, both surfaces with scattered coarse white 
hairs. Inflorescence terminal, crowded, consisting of many simple race- 
mes forming a terminal panicle up to 10 cm. in length and 4 or 5 cm. in 
diameter, the individual racemes 4 cm. long or less, ascending, the lower 
ones subtended by leaves. Bracts narrowly lanceolate, 3 mm. long, 
1-flow ered, the braeteoles acicular, 1 mm. long; pedicels about 1 mm. 
long, strigose. Calyx tube 4-angled, narrowly ovate, slightly strigose, not 
rugose nor pellucid-punctate but slightly strigose-hispid, the lobes erect, 
lanceolate, about 1.5 mm. long, acuminate, glabrous. Petals boat-shaped, 
slightly aculeate-hispid on the keel, 2.2 mm. long. Stamens 8; anthers 
1.5 to 1.7 mm. long.
