glabrous, alternatingly branched from below the middle, the 
ultimate branchlets very slender though relatively short; flow- 
r ers alternatingly scattered or grouped toward the ends mostly, 
strongly and sweetly fragrant; pedicel whitish, 6 mm long, 
slender, glabrous, enlarged toward the distal end; calyx green- 
ish, 3 mm long, punctate or pulverulent, glabrous, deeply 
cup shaped, subelliptic to subobovate, rounded or truncate

in width, united toward the base, very strongly and imbri- 
catingly folded in the old flowers and assuming an ovoidly 
elongated shape, persistent; petals membranous, pure white, 
glabrous, 6 mm long and one fourth as wide at least, ob- 
long, widest toward the broadly rounded apex, widely spread- 
ing in anthesis, finely veined, subequal, also 5 in number, 
early falling; stamens 10 or more, the inner series are one 
third shorter and sterile; filaments slender, much dilated at 
the bases, glabrous, the longer or outer ones 5 mm in length, 
at their distal ends slightly expanded; anther pale yellow,

In my opinion it is specifically distinct from 752 Cuming 
or the type specimen of Rourea heterophylla Planch.
