Inflorescence lax, few-flowered, glandular pubescent; Flowers 4- or 5-merous. Sepals 3-4 mm, obtuse, herbaceous or membranaceous at the very apex, glandular pubescent. Petals slightly longer than sepals, subemarginate. Capsule straight, 4-6 mm; Seeds 1-1.5 mm.

From East Africa and Madagascar throughout India to Australia. In Malesia: Java, Timor, Celebes and Papua New Guinea.

Taxonomy

There is a considerable variation in height and leaf size evidently due to environmental conditions. Möschl, l.c., described three varieties, of which var. ruwen-zoriense (Williams) Möschl matches the material from Java. There are also collections matching var. parvifolium Möschl. We do not find it necessary to maintain formal subspecific classification due to the polymorphy of the species, and therefore follow the treatment of Wadhwa, l.c.
