HELOSPORA FLAVESCENS. 
Native of Sumatra. 
A small tree. Leaves opposite, short-petioled, ovate-lanceolate, 
acuminate, very smooth, entire: from three to five inches

persistent. Corolla yellow, tube much longer than the ca- 
lyx; mouth naked; limb four-parted, spreading ; segments 
oblong. Æstivation valvate. Stamens four, within the tube ; 
filaments scarce any ; anthers linear, obtuse, flattened, two- 
celled. Ovary subglobose, four-lobed, crowned by a necta- 
rial ring or disk, polysporous, not divided into cells, but 
having the ovula implanted in its substance and arranged 
in double lines in the form of a cross. Style composed of 
four connate threads, which diverge at top, somewhat longer 
than the tube. Stigmas four. Berry globose, with four 
rounded angles and furrowed between, crowned with the 
calyx, many-seeded. Seeds long, linear, inserted perpen-
