Stipules of the cataphylls lanceolate, 1-1.3 mm long, scarious; those of the leaves narrowly lanceolate, 0.7-1 mm long, scarious with a pinkish or olive midrib. Proximal nodes ♂, distal ♀.

Holotype: Pakistan, Punjab, ? Sialkot, Ravi-Chenab Doab, ‘Jummooghat’, Oct. 1846, Thomson s.n. (K); Isotype (GH).
Distribution: Pakistan, Kashmir, N.W. India; introduced into Arabia, Africa and the West Indies; on sandy clay soil in moist habitats, e.g. parks, gardens, canesugar fields. Near sea-level to 4500'/1370 m.
The records for Phyllanthus debilis Klein ex Willd., a native of S. India and Sri Lanka (see Stewart, op. cit.: 455. 1972), almost certainly refer to this species. I have seen no specimens from Pakistan.
