118 THE BOTANY OF WESTERN AUSTRALIA. 
the rocks of the White Peak, and other hills of Moresby's range: the 
cones are longer and differently shaped from any of this section which 
I am acquainted with; the flowers have not been seen. : 
The ironstone hills to the north of Dundaragan, and most of the 
hills of Gardener's range, produce (but very sparingly) a new Zsopogon, 
with linear leaves; it grows about a foot high, and bears large rose- 
coloured heads of flowers; this species resembles Z. Jatifolia in its 
flowers, but the foliage is altogether different. On the same hills I 
found another new species of Isopogon, near J. asper of Mr. Brown, 
but it differs from it in the following characters :—asper has unbranched 
stems, the new species has numerous branches; J. asper has smooth 
anther-tubes, in the new species they are covered with white hairs; 
the scales also which surround the flowers are hairy and bent inwards, 
in Z. asper the scales which surround the flowers have glabrous re- 
curved points. i 
An ironstone hill to the west of the river near the first spring on the 
hill, yields (sparingly) a very curious Isopogon, in habit and foliage so 
like Adenanthos sericea that when not in flower it may be easily passed 
over for that plant. I also met with a new trifid-leaved Isopogon with 
much broader leaves; it is a very rare plant, and seen only in one spot, 
on the great sand-plain to the north of the Diamond Spring. 
Persoonia produces several new species, but I shall only notice one 
which is remarkable for its beauty; it is found abundantly on the first 
sand-hill which the road crosses to the north of Dundaragan. It grows 
in a low bush with glaucous spathulate leaves, about two inches long, 
and about half an inch broad near their points; the branches are nu- 
merous, and from the axils of every leaf, on their upper parts, upright 
racemes of golden-yellow flowers, from nine inches to a foot long, are 
produced ; this is by far the finest species of the genus. 
The ironstone hills between Dundaragan and the Smith river, pro- 
duce in abundance two new Grevillee,—one a prostrate plant with pin- 
nate leaves and branched racemes of rose-coloured flowers, in size and 
form resembling the flowers of G. bipinnata ; this is a fine species. 
The other new species, which grows on the hills, is a slender, upright- 
growing plant, with hispid trilobate leaves, and long spikes of white 
flowers; it comes nearer G. Manglesioides than any described species. 
A new Grevillea, of the Manglesia section, grows near the first spring 
on the Hill river, on the same hill with the Adenanthos-like Isopogon ;
