Eobust, erect, sligtly l)ranelied. a1)out (>0 em. high, the stems terete, 

 scal)rid. the older ones reddish brown, the younger parts rather densely 

 clothed with long brittle white hairs. Leaves elliptical-ovate 2 to 3 cm.

 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-fiowered, the bracteoles acicular, 1 mm. long; pedicels about 1 mm. 

 long, strigose. Calyx tube 4-a.ngled, narrowly ovate, slightly strigose, not 

 rugose nor pellucid-punctate but slightly strigose-hispid, the lobes erect,
