 the habit of a Leonotis, from a few inches to a few feet high ; the 

 stem trichotomously branched; and the spreading branches obtusely 

 tetragonal, 4-furrowed, minutely glandular, pubescent with short 

 downward hairs, pallid ; leaves elliptical or oval, obtuse at the 

 apex, somewhat narrowed towards the base, thinly herbaceous, 

 softly puberulous, minutely glandular, dark green above, paler 

 and more pubescent along the veins beneath, strongly crenate- 

 dentate, f to 21 in. long by f to li in. broad ; petioles ranging up 

 to ~ in. long, pubescent ; flowers white, § in., subsessile or very 

 shortly pedicellate, numerous, crowded in axillary and subterminal 

 verticils ; verticils not conspicuously bracteate at the base, sessile ; 

 bracts minute ; calyx tubular-turbinate, bilabiate, ^ in. long or 

 in fruit rather longer, pubescent outside, naked inside ; the tube 

 about y^Q- in. long, 10-ribbed, not contracted at the mouth; the
