Seeies I. Valvat.e. — Petals valvate. 



1. B. grandisepala, F. Muell. Fragm. i. 6G. A slirub witli tomcn- 

 tose branches. Leaves simple, nearly sessile, oblong-lanceolate, obtuse, 1 to 

 l|^in. long, softly lioary-tomentose on both sides, the edges flat, the midrib 

 very prominent underneath. Pedicels axillary, solitary, sliort, 1-flowered. 

 Sepals ovate or ovate-lanceolate, tomeutose, valvate, attaining* 5 or 6 lines. 

 Petals^ valvate and tomentose like the sepals, but smaller, and enclosed in 

 them in the bud. Filaments slightly hirsute, clavate and glauduUir at the 

 top. Anthers scarcely apiculate. Ovary pubescent.

2. B. artemisisefolia, F, Muell. Fragm, i. 66. A shrub, clothed all 

 oyer with a soft hoary close or velvety tomentum. Leaves all or neai'ly all 

 pmnate. Leaflets 7 to 11 or more, crowded on a short common petiole, 

 linear, obtuse, rarely exceeding \ in. and often much shorter, the marguis 

 closely revolute. Peduncles axillary, solitary, short, 1-flowered. Sepals lan- 

 ceolate, tomentose, valvate, attaining 3 to 4 lines. Petals lanceolate, valvate 

 Md tomentose like the sepals, but smaller and enclosed in them in the bud. 

 Filaments slightly hirsute, clavate and glandular at the top. Anthers scarcely

Var. Wihoni, F. Muell. Branches more villous. Leaflets short, oblong, and less 

 crowded. — N.W. coast, Bynoe ; Vansittart's Bay, A. Cunrdnglam ; Victoria river, 



t*. Mueller, Fragm. ii. 179, refers this species as a variety to B. gi'andisepala^ and some 

 of H. Brown's specimens have some of the leaves undivided; yet I have seen no a})proachto 

 the large flowers of B.grandUp})ala, and i retain the two as distinct until really intermediate 

 specimens shall have bceu observed. 



3. B. affinis, R. Br.Uerl. A shrub, with numerous slender divaricate 

 branches, pubescent when young, at length glabrous. Leaves pinnate ; leaflets 

 7 to 15, linear, obtuse, mostly 3 to 4 lines long, the margins revolute, pubes- 

 cent when young, glabrous at least above Avhen full-grown, the pairs distant. 

 I^edicels very short, axillary, 1-flowered. Sepals broadly lanceolate, subidate- 

 acuminate, 2 to nearly 3 lines long, slightly pubescent, very thin l)ut appa- 

 rently valvate. Petals similar to the sepals, and about the same length, but- 

 narrower, valvate. Filaments clavate, and glandular at the top. Anthers 

 scarcely apiculate. Seeds smooth, but scarcely shiniug,

4.'B. filicifolia, J. Cnnn. Herb, Branches rather slender, tomentose- 

 P^jbescent or villous. Leaves pinnate; leaflets 12 io 20 pairs, with a 

 terminal odd one, ovate or oblong, 1 to 2 lines long, pubescent, the margins 

 slightly recurved. Peduncles axillary^ slender, often \ in. long, bearing a 

 smgle small flower. Sepals lanceolate-valvate, tomentose, atiaining about 

 2 lines. Petals lanceolate, valvate and tomentose, like the sepals, and of the 

 same size. Filaments clavate and glandular upwards. Anthers shortly 

 fipiculate. Style pubescent.
