 to elliptic-oblong, scabrid, acute or acuminate, base narrowed, slightly 

 cordate, 6 ta 12 cm long. Racemes solitary, pendulous, up to 30 cm in 

 length, the pedicels usually much longer than the pubescent calyx-tube.

 panicles, the involucral bracts about 6, colored, enlarged and persistent 

 in fruit. Calyx oblong-obovoid or narrowly funnel-shaped, 4- to 8-toothed. 

 Corolla-tube a little longer than the calyx, cylindric, usually 6-lobed. 

 Stamens as many or twice as many as the corolla-lobes. Ovary 2-ceIled,
