Tree 5–24 m tall. Branchlets densely ferruginous-tomentose. Leaves mostly imparipinnate, 10–65 cm long, with 2–19 leaflets, moderately to densely covered with appressed, lustrous, ferruginous to crimson hairs when immature, glabrescent; rachis prominently winged in intermediate and some adult leaves; leaflets mostly elliptic to ovate, acuminate, petiolulate, 3–18 cm long, 1.1–5.5 cm wide. Conflorescence terminal, axillary or ramiflorous, erect to spreading, with 0–6 lateral branches; rachis 3–10 cm long; flower pair bracts 0.5–1.5 mm long; peduncle 1–2.5 mm long. Tepals 7.5–12 mm long, cream, densely appressed-ferruginous-pubescent on outside. Gynoecium 6.5–10 mm long, green, glabrous. Fruit 1.5–1.9 cm long, 1.3–1.6 cm wide, blue-black. Fig. 176.

Occurs on near-coastal ranges, from Mt Lewis to Eungella Range, Qld. Occurs in rainforest on granite and basalt, at 600–1200 m alt. Flowers Aug.–Nov. and Mar.–May; fruits Jan.–Mar. Map 462.

The flowers are not scented.

Gevuina bleasdalei closely resembles G. papuana (Diels) Sleumer, from northern New Guinea, differing chiefly in its more lustrous, less dense, paler, appressed indumentum. Smith & Haas (Amer. J. Bot. 62: 142 (1975)) included these two species in the genus Bleasdalea with three others from Vanuatu and Fiji. The latter group has distinctive, laterally compressed, inequilaterally obovoid fruits, a character that Smith & Haas predicted would also be found in G. bleasdalei and G. papuana , the fruits of which were then unknown. Fruits of G. bleasdalei have been collected (e.g. Sankowsky 1267 , cited above) and closely resemble those of G. avellana . It seems wisest to retain G. bleasdalei and G. papuana in Gevuina , at least until further research clarifies the relationships of these taxa.

A.C.Smith (1975) argued that the generic name Bleasdalea is nomenclaturally invalid and published the name Turrillia to replace it. The latter is typified by the Fijian species T. vitiensis (Turrill) A.C.Sm. I consider that Turrillia should be circumscribed to exclude G. bleasdalei and G. papuana .
