H. tetraptera are almost obsolete as in Styrax. Besides 
these points of difference, while H. tetraptera produces an 
abundance of blossoms continually, even upon plants a foot 
high, the present species scarcely flowers under any cir- 
cumstances. 
A hardy shrub, with the old branches smooth and 
brown, and the young branches downy. Leaves ovate 
oblong, with a short point, downy on each side, green 
_above, glaucous beneath; the young ones entire, the full 
grown ones toothletted. Mowers whitish, a little smaller 
than in H. tetraptera, disposed in somewhat compound 
pendulous racemes, appearing at the same time as the 
Jeaves. Calyx obovate, downy, 4-toothed, with ovate 
acute teeth. Petals rugose, downy, obovate, obtuse, in 
estivation imbricated. Stamens 8, the length of petals. 
Filaments hairy. Style included. :
