2. B. rupicola (found upon rocks), A. Cunn. Herb.; Benth. FI. Austr. ii. 
162. A shrub with the habit and flowers of B. carinalis, but very different

£ to lin. long, rarely 2 lines broad, narrowed or scarcely obtuse at the base, 
coriaceous, veinless except the midrib. Pedicels short, the small bracteoles near

3. B. prostrata (prostrate), R. Br. in Ait. Hort. Kew ed. 2, iv. 268 ; Benth. 
FI. Austr. ii. 162. A small shrub or undershrub with a thick woody stock and

flattened, usually pubescent. Leaves distichous, ovate or oblong, obtuse or

hairs, the petioles frequently rather long and slender. Pedicels usually much

2 lines long, the 2 upper lobes broadly falcate and united above the middle, the 
lower ones short and narrow. Standard fully twice as long as the calyx ; wings 
and keel considerably shorter. Ovary very shortly stipitate, glabrous or ciliate, 
with 6 to 10 ovules. Pod nearly sessile, glabrous, f to lin. long, rarely 2J lines 
broad. — Bot. Mag. t. 1493; DC. Prod. ii. 117 ; Hook. f. FI. Tasm. i. 94 ; B. ovata,

Hab.: Wide Bay, Bidwill, and in more southern localities. 
In the southern specimens the stems are usually short, very slender, almost filiform, in several 
of the northern ones they are longer, firmer, and more branched. The size of the flowers is 
variable, and here and there a few flowers, possibly imperfect ones, may be found abnormally 
almost sessile. — Benth.
