Finely leafy, aromatic shrub to 1 m, sometimes branched from base. Leaves sessile, ascending, linear-lanceolate, sharply mucronate. Flowers in small, terminal clusters on short racemes, white.

Diosma meyeriana is recognised as a distinct species being a shrub arising from a single main stem, entirely glabrous; with leaves linear-lanceolate, sessile, alternate, adpressed erect with a small straight point; with flowers small, crowded, sub-sessile with petals glabrous, closing again after anthesis and persisting; with fruits not oily and with matt seeds. It looks very like D. hirsuta which however has leaves petiolate and D. acmaeophylla which has the petals pubescent. From: Williams, IJM. 1982. Studies in the genera of the Diosmeae (Rutaceae): 14.
