Apparently a variable plant. Dr. Masters (in Oliver’s Flora of 
Trop. Africa, i. 226), describes the African specimens as having no 
stamens or staminodes alternating with the 5 phalanges of stamens. A 
specimen in the Calcutta Herbarium from Java has the under surface 
of the leaves softly hairy. 
5. Helictekes, Linn. 
Trees or shrubs, more or less stellate-pubescent. Leaves simple. 
Flowers axillary, solitary or fascicled. Calytc tubular, 5-fid, often irre- 
gular. Petals 5, clawed, equal or unequal, the claws often with ear- 
shaped appendages. Staminal column surrounding the gynophore, 5- 
toothed or lobed at the apex ; anthers at the top of the column, 2-celled. 
Five staminodes below the apex of the column. Ovary at the top of the 
column, 5-lobed, 5-celled ; styles awl-shaped, more or less united, slight- 
ly thickened and stigmatose at the tips ; ovules many in each cell. 
Follicles spirally twisted, or straight. Seeds tubercled ; albumen scanty ; 
cotyledons leafy, folded round the radicle which is next the hilum. — ■ 
Distrib. About 30 species, natives of the tropics of both hemispheres.

1. H. Isora, Linn. Spec. 1366. A shrub or small tree; young
