Lagerstroemia floribunda auct. non Jack: Blume (1856) 126, t. 41B (based on the cited figure, drawn from material from Timor, depicting flowers and fruit, and clearly representing L. engleriana , but material from Timor collected before 1856 is not in L).

Inflorescences terminal, lax, broadly or narrowly pyramidal, 4–40 cm long, grey or rust coloured hairy. Flowers: bud obconical, c. 1 mm nippled at apex, 10–12 mm long; pseudopedicel 3–4 mm long; calyx tube c. 6 mm long, 6-ridged, with a small inwards bent auricle at each sinus, calyx lobes (sepals) 6, glabrous or possibly at apex somewhat hairy within, c. 3 mm long; petals pink-purplish, broadly elliptic, c. 16 mm long (including c. 5 mm long claw); stamens numerous, radially dimorphic; ovary hairy. Capsules (grey) hairy at least at apex, not shagreen but often approaching this facies, drying (brown-)black, 15–18 mm long, (4–)5-valved; fruiting calyx 6-ridged; calyx lobes glabrous within; fruiting pseudopedicel 2–10 mm long.
