or narrowly elliptical, narrowed to an acute or apiculate apex, wedge- 
shaped at the subsessile base, more or less scabrous above, rather paler 
and somewhat hairy beneath, ranging up to 4 by 1 in., margins 
scabrous, veins rather slender; stipules with a short broad sheath and 
about 5-7 equalling or longer sete, hairy. Flowers ranging up to 
4 in. long, numerous, crowded in dense sessile terminal and axilla 
heads, exceeded by the uppermost spreading leaves. Calyx-teeth 4, 
lanceolate, acute, ciliate, rather longer than the ovary ; tube hairy 
above. Corolla elongate-funnel-shaped, glabrous except the tip of 
the lobes. Anthers exserted. Stigma subcapitate, bilobed. Fruit 
bursting around the base; cocci dehiscing upwards inside from the 
base leaving the septum free.—H. ampliatum, A. Rich. 1. ¢. 849.
