Leaflets 3 to 9, glabrous 2. T. actinophylla. 



1. T. Argyrodendron (leaves silvery beneath), Benth. " Boiong." All 

 the varieties form tall straight- stemmed trees, with broad, flat abutments at the 

 base ; glabrous except minute scurfy scales on the young shoots, inflorescence, 

 and under side of the leaves. Leaflets 3 or 4, or sometimes on young trees 6, 

 petiolate, usually lanceolate, 3 or 4in. long, silvery on the under side. Petioles 

 very variable in length, sometimes only a few lines, at other times from 1 to 

 nearly 2in. Panicles dichotomous, the upper ones sometimes exceeding the 

 leaves. Flowers very numerous. Calyx broadly campanulate, about 3 lines 

 diameter. Carpels with a semi-orbicular or with a straight wing about lin, long.

Hab.: A common tree in the scrubs of southern Queensland. 



The common or silvery-leaved " stavewood." Wood light-coloured, close-grained, tough and 

 firrri ; may be used as a substitute for English beech. — Bailey's Gat. Ql. Woodn No. 29. 



Var. 1, grandiflora', Benth. Fl. Austr. Calyx 4 lines diameter. Stigmas short and broad. — 

 Port Denison, Benth., I.e. 



Var. 2, angustifolia, Bail. Cat. Ql. Woods, No. 29b, and No. 1 Occasional Papers on the Ql. 

 Flora, 1886. This differs in foliage, the 3 leaflets being naiTow, often under Jin. wide, and 2 or 

 Sin. long. Petioles of normal form, silvery or approaching coppery on the under side. — 

 Endeavour Biver. Wood of a light-grey colour, close-grained, hard and tough, suitable for 

 making tool handles. — Bailey's Cat. Ql. Woods, No. 29a. 



Var. 3, macrophylla, Bail. Bot. Bull. ix. 5. A large tree. Leaflets 3, rarely 2, silvery with a 

 slightly brownish tinge on the under side, oblong, often abruptly acuminate, 5 to lOJin. long, IJ 

 to 3Jin. broad, on nearly terete, striate, petioles, 3 to over 6in. long. Flower-panicles rather 

 large and loose, flowers small. Carpels not seen. — Wood light-coloured, prettily figured, tough 

 and firm. — Bailey's Cat. Ql. Woods No. 29 bis. 



Var. 4, trifoliolata (leaves of 3-leaflets) {!'. trifoliolata, P. v. M. Fragm. ix. 43). A tall tree. 

 Leaves with slender petioles 2 or Sin. long, usually bearing 3 lanceolate leaflets 3 or 4in. long, 

 often dark from the numerous small coppery-coloured scales on the under side. Fruit usually 

 coppery like the leaves, the wing nearly 2in. long. This tree is plentiful in many scrubs north 

 and south. Wood similar to the foregoing kinds, but rather darker; known as "stavewood," 

 Bailey's Cat. Ql. Woods No. 29a. Leaflets sometimes infested with the fungus Dimerosporiuvi 

 Tarrietim, Cke. and Mass. 



Var. 5, peralata (wings of seed very large). Bail. Occ. Pap. on Ql. PI. No. 1. Johnstone 

 River Bed Beech. "Peirir," Upper Barron River, J. F. Bailey. A large erect tree, the 

 stem often exceeding 5ft. in diameter. Leaves trifoliolate, the petioles somewhat angular, 

 mostly 2 or 3in. long. Leaflets lanceolate, from 4 to Tin. long and from 1 to 2in. broad 

 towards the middle; the indumentum more silvery than usual in this species, but with the 

 same numerous small brown scales. Inflorescence not sent by collectors. Samaroid carpels 

 muricate, oval or globose, J to Jin. long by about Jin. diameter, furnished with an oblong, 

 oblique, erect wing 2 to 4in. long by about Ijin. broad, clothed with the same rusty stellate scales 

 as the under side of the leaves. Wood resembling cedar in appearance, but harder ; suited for 

 indoor and cabinet work; soon 4eoays if exposed to bad vreathei.— Bailey's Cat. 01.
