Habitat

Corymbia scabrida grows in woodland communities usually as a co-dominant in association with Eucalyptus melanophloia, Corymbia clarksoniana, Angophora leiocarpa, E. chloroclada and C. polycarpa. Other associated species include Acacia leiocalyx, Callitris columellaris and Acacia shirleyi. It occurs on low sandstone ridges and flat top hills on shallow, sandy or loamy soils, occasionally on gravelly textured soils (Halford, 1996; Queensland Herbarium, 2012).

Description

Corymbia scabrida is a tree growing to 15 m high. The bark is persistent, soft, loosely scaly and fibrous, tessellated, yellow-brown to greyish yellow and yellow to orange on freshly broken surfaces. The juvenile leaves are disjunct after a few nodes, setose with bristle-glands, orbicular to oblong-ovate and peltate after about node 8. The juvenile leaves grow to about 80 mm long and 55 mm wide. The petioles grow to 15 mm long. The intermediate leaves are disjunct, setose, ovate to suborbicular. Later the intermediate leaves become narrower, acute to rounded, peltate, often persisting into the mature canopy, 8cm long and 60 mm wide, with petioles to 10 mm long. The adult leaves are disjunct, scabrid, concolorous, dull, broad-lanceolate or narrow-elliptical to ovate or oblong in shape, apiculate to rounded, 6 to 12 cm long and 16 to 35 mm wide, with petioles 7 to 16 mm long. The intramarginal vein is distinct. The oil glands are abundant and regular. The umbellasters are 7-flowered. The peduncles are 8 to 20 mm long and the pedicels are 1 to 2 mm long. The mature buds are usually scurfy-white with remnants of rubbery cuticle, ovoid in shape, 7 to 8 mm long and 5 to 6 mm in diameter. The fruits are globoid, often verrucose, 9 to 11 mm long by 8 to 10 mm in diameter. The seeds are glossy, red-brown, dorsiventrally compressed with a median dorsal keel, 2 to 3 mm long by 1.5 to 2.5 mm wide (Hill and Johnson, 1995).
Corymbia scabrida is distinguished by the relatively narrow, persistently scabrid-setose, but not always peltate leaves with short petioles in the mature canopy (Hill and Johnson, 1995).

Reproduction

Very little is known about the life history of Corymbia scabrida. Flowers have been recorded in October and fruits throughout the year (Queensland Herbarium, 2012).
