blue or purple flowers. Among the Hakeas, Frazer’s cris- 
tata is easily recognised by the curious bicrested form of the 
seed-vessel ; his Petrophila linearis is a fine species, producing 
large flowers of a lilac colour, but from the size and shape 
of the bunches, they remind me of the English honeysuckle. 
The Rocky Pass, where the river Helena makes its way through 
the Darling range of hills {between Wallup and Neerdup, 
displays some noble plants. One of the finest is a large scarlet 
Melaleuca, with large scarlet flowers and lanceolate leaves 
two inches long; a fine white Everlasting-flower, which I 
think is scarcely distinct from the plant called in England the 
Botany Bay Xeranthemum ; and the beautiful heart-leaved and 
the awl-leaved pink Everlastings grow about the Rocky Pass. 
A dwarf green and crimson Anigozanthus (A. humilis, Lindl. 
l.c.t. 6.), is common here on the sides of the hills. Of the fra- 
. Brant genus Boronia, two species grow at the Rocky Pass on 
the banks and islands in the Helena, and three on the sides 
of the hills. Of the equally beautiful but fetid Bauera I have 
found three kinds, their flowers smell like Dillenia scandens: 
two species of a beautiful climbing genus* allied to Billar- 
diera, but having a dry two-celled many-seeded capsule, grow 
‘in the islands and three more species of the same genus, some 
9f them very sweet-scented, inhabit the sides of the hills. The 
native Yam, a true Dioscorea, the finest vegetable this country 
naturally produces, with seven or eight species of Hamodorum, 
constitute the principal food ofthe natives in the way of vege- 
tables; they eat the roots; all the species are mild and nutri- 
tious when roasted, but acrid when raw. The islands about 
the Rocky Pass produce a curious shrub with oblong downy 
leaves and clusters of flowers collected in a common calyx as 
in Syngenesia; as nearly as I can ascertain, each individual 
flower has 10 stamens, a style, and a seed-vessel resembling
