Queensland Crepe Myrtle; Crepe Myrtle; Native Crepe Myrtle

A small tree seldom exceeding 30 cm dbh. Living bark layer quite thin. Inner blaze and cambial layer turning pink or purplish on exposure. Deciduous; leafless for a period in September or October.

Leaf blades about 7-17 x 2-5 cm. Petioles short. Stipules visible on young shoots, small, with a short swollen base and abruptly tapering into a small, prickle-like tip. Lateral veins curved throughout their length, sometimes forming loops inside the blade margin. Bark on the larger twigs tending to be scaly and/or slightly stringy.

Calyx lobes about 2-4 mm long, valvate, longitudinally ribbed, apiculate in the bud, hairs branched (dendritic). Petals about 16-10 mm long. Staminodes pink-red, much larger than the stamens.

Calyx lobes persistent. Seeds winged at one end, seed plus wing about 9 x 3-4 mm.

Cotyledons broadly obovate, about 5-7 mm broad, base cuneate. At the tenth leaf stage: leaves elliptic, shortly petiolate, apex acuminate, glabrous on the upper surface, stem wings narrow. Seed germination time 12 to 246 days.

Occurs in WA, CYP and NEQ. Altitudinal range from near sea level to 500 m. Grows in monsoon forest and gallery forest. Also occurs in New Guinea and other islands in Malesia.

This widespread tree which usually occurs in drier forests is already in cultivation. This species has horticultural merit producing large numbers of mauve, pink or purple flowers which are large and showy.
