flowers, and in that state it may contest the prize of beauty even with 
V. grandis itself. 
A new lilac-flowered Verticordia, with glaucous, heart-shaped, in- 
dented leaves, with several unbranched stems from the same root, which 
terminate in small corymbs of flowers, appears sparingly about nine 
miles to the north of the Hill River, and also near the base of Mount 
Lesueur; and I have seen specimens which were gathered by Mr. 
Edward Whitefield, near his residence on the Moore River; this is one 
of the rarest species of the genus. A new Verticordia, growing five or 
six feet high, with heart-shaped leaves and drooping corymbs of yellow 
flowers, grows abundantly on the sand-plain to the northward of the 
Hutt River. Another beautiful yellow species, attaining twice the 
height of V. grandiflora, with larger flowers and longer leaves, and 
without the hairs which grow on the stem of one variety of that plant, 
and differing from both varieties in growing to a much larger size, is 
found on sand-plains near the Smith River. I have several other sup- 
posed new species of Verticordia, but they require to be compared with 
others in my herbarium. 
Calycothriz produces several new species, with both purple and yel- 
low flowers, but the characters which distinguish the species of this 
beautiful genus are so minute I cannot describe them in a communica- 
tion of this kind. The only species I shall particularly notice is one 
which grows in form of a pyramid; the plant rises about two feet 
high and is about a foot wide near the ground, tapering up to a point ; 
the leaves are small and heath-like, the branches crowded as thick as 
they can grow together; the outside of the pyramid is one mass of 
purple flowers, which almost hide the leaves. . This curious and beau- 
tiful plant I saw in abundance near the spring called the “ Arrow Well.” 
Of Labillardigre’s genus Pileanthus I gathered two species, and I 
saw a portion of a third, which was brought by my son, James Drum- 
mond, from the Upper Irwin. The first is a species with large purple 
flowers, growing in corymbs, not unlike a purple Sweet-William. This 
species grows on the limestone hills to the north of the spring Diamond 
of the Desert; the other species I met with has red flowers, it is near 
one I found on the Wanjan Hills, but the flowers are smaller and more 
numerous in the heads, and the habit of the plant is different; the 
species I saw from the Upper Irwin has heart-shaped leaves and orange- 
coloured flowers.
