Branchlets terete, robust, glabrous, dark-brown when dry. Leaves: blades oblong-lanceolate to obovate-lanceolate, with stiff hairs on both sides; nervules reticulate, conspicuously prominent beneath. Stipules big, partly covering the cymes, ovate to triangular-ovate or broadly triangular, 1–2 by 1– 2 cm, coriaceous with membranaceous margin, glabrous. Inflorescences sessile; bracts numerous, linear, hirsute, forming a dense head. Flowers sessile, sealed (hidden) by bracts.

Note — Lasianthus scabridus differs from L. griffithii in having stiff hairs on both sides of leaves, reticulate nervules conspicuously prominent beneath. It is suitable to sink L. scabridus to a variety of L. griffithii as var. scabridus .
