Australian Plants. 39 
leaves, either axillary, solitary, or collected in terminal few- 
flowered heads; bracteoles ovate, keeled, shorter than the tube 
of the silky calyx; standard surpassing considerably the 
length of the keel, but little that of the wings; style below 
the middle appressed- hairy, unbearded on the apex; pod 
somewhat hairy, ovate, slightly compressed; seeds destitute 
of a strophiola. 
In arid plains, at the foot of Mount Abrupt, in Kangaroo 
Island, and Encounter Bay. 
18. Burtonia subalpina. 
Twigs almost silky, soon glabrescent; leaves crowded, 
undivided, filiform, channelled, awnless, smooth, scabrous; 
stipules longer than the petiole; flowers sessile, terminal, 
capitate; calyx and germen villose-silky; corolla purple; 
style below hardly broader. 
On the rocky summit of Mount William, at an elevation 
of about five thousand feet. 
Not dissimilar to B. diosmifolia, from which it differs as 
well as from all other Western Australian species of the 
genus in producing stipules. The pod is yet unknown. 
19. Bosstaea distichoclada. 
Erect, unarmed; branches and twigs in two rows, terete, 
grey-velutinous, densely foliate; leaves small, on very short 
petioles, bifarious, assurgent, coriaceous, nearly kidney-shaped, 
at the top awnless and divided into two very short lobes, 
their margins recurved, above scabrous, on both sides, with 
the exeeption of middle rib, glabrous; stipules ovate- or 
lanceolate-subulate, long persistent, at length reflexed, often 
of the length of the leaves; pedicels short, axillary, solitary, 
with rounded or oyate ciliate bracteoles; upper lip of the 
somewhat silky calyx bifid, lower lip three-parted; pod much 
compressed, roundish-rhomboid, covered with rusty downs, 
containing from one to three brown black-spotted seeds. 
In the Australian Alps from the Mitta Mitta to the tribu- 
taries of the Snowy River, as well between rocks as along 
the peaty margins of the rivulets. 
This singular and beautiful plant descends never to regions 
lower than four thousand feet; and being at five thousand for 
many months during the year covered with snow, it will, 
like the new previously mentioned Burtonia and many other 
of our alpine plants, form an exquisite addition to the garden 
flora of colder countries.
