Zm-io.] XXIX. KUTACEi^. IS'd 



or rarely 2 iu each coccus, oblong; testa crustaoeous.— Shrubs or rarely small 

 trees, glabrous, hirsute or tomentose. Leaves usually opposite, with 3 leaflets, 

 rarely alternate or simple. Flowers white, usually small, axillary, in small 

 trichotomous cymes or rarely solitary. 



The species are all enrlemic in Australia, and F. v. Mueller considers them as forming a 

 section only of BoronUt : but the characters and habit appear to me sufficiently distinct to justify 

 the maintenance of so old-established and generally adopted a genus. — Benth.

 Leaflets with revolute margins. Cymes pedunculate. 

 Branchlets angular, glabrous. Leaflets J to lin. on a distinct common 



petiole 1. Z. Icnvigata.

vertioillate 2. z. aspalathoides. 



Anthers minutely apiculate. Plant pubescent or hirsute, rarely tomentose.

 tomentose. 

 Leaflets 3, small, obovate or obcordate. Flowers very small .... 4. Z. obcordata.

 Glabrous or slightly pubescent.

1. Z. laevigata (smooth-leaved), Sm.: DC. Prod. i. 723 ; Benth. Fl. Austr. 

 i. 304. A glabrous, erect shrub, the branchlets angular. Leaflets 3, on a 

 common petiole of 1 to 3 lines, linear, pointed, J to lin. long, the margins closely 

 revolute. Cymes few-flowered, mostly about as long as the leaves. Calyx-lobes 

 short and broad. Petals fully 8 times as long as the calyx, broad, imbricate, 

 slightly tomentose outside. Connective of the anthers distinct, produced beyond 

 the cells into a short point or appendage. Style very short. Cocci and seeds of 

 Z. Smithii. — Deless. Ic. Sel. iii. t. 49 ; Paxt. Mag. Bot. ix. 77, with a fig.; 

 Boronia Icevigata, F. v. M. Fragm. i. 101 ; Z. remluta, A. Cunn. in Field, N. S. 

 Wales, 380. ' 



Hab.: Sandstone rocks near Mount Pluto, Mitchell; Mount Lindsay, Fraser. 



Var. lasAAora. Leaflets longer (1 to IJin.), on a longer common petiole. Flowers much 

 smaller, in a looser cyme. Petals not twice as long as the calyx. — Stradbroke Island, Fraser ; 

 Moreton Island, F. v. Mueller. 



2. Z. aspalathoides (Aspalathus-like), A. Cunn. Herb.; Benth. hi. Austr. 

 i. 305. A heath -like shrub, the branches terete and pubescent, but usually with 

 a decurrent glabrous line. Leaflets 3, sessile or with the common petiole so 

 exceedingly short that they appear verticillate, lanceolate or linear, rarely above 

 3 lines long, or when very luxuriant 4 or 5 lines, the margins revolute, glabrous 

 or slightly pubescent. Cymes usually 8-flowered, rather longer than the leaves. 

 Calyx-lobes broad, obtuse or acute. Petals about 2 or 3 times as long. Anthers 

 tipped with a small obtuse appendage. --L'occih^V^ larir/ata, F. v. M. PI. Vict. .i. 

 Ill (In part). 



Hab.: Near Mount Playfair, F, r. M. 



3. Z. pilosa (pilose), Rudiie, in Trans. Linn. Suv. x. 293, t. 17 ; Benth. Fl. 

 Austr. i. 305. A shrub or undershrub, the branches terete and densely pubescent 

 or hirsute. Leaflets 3, with a short common petiole, linear, oblong or lanceolate, 

 obtuse, f to fin. or rarely lin. long, the margins recurved or revolute, slightly 

 pubescent or glabrous above, more or less hirsute or tomentose underneath.
