As my description is taken from dry specimens I cannot, 
say whether it be a tree or shrub, but the large woody speci- 
mens evidently show it to be perennial. Leaves short-petiol- 
ed, alternate, obovate, oblong, obtuse-pointed, entire and 
smooth on both sides, six or more inches long and less than 
three broad. Stipules none. Racemes generally solitary, 
from the naked woody branchlets below the leaves, very 
long and completely clothed to the base with numerous — 
beautiful, diverging, pretty large, delicate flowers. .Bractes 
minute. Calyx none. Petals four, very long and slender,

then at the apex, and soon after become revolute. _ Nectary, 
four scales embracing the lower part of the germ. Filaments 
four, short, inserted into the petals above the middle. An- 
thers linear, curved in an opposite direction to the petals. 
Germ above, ovate, style long and slender, Stigma clubbed,
