_ more open, and here the first Kingias make their appearance; 
_ they have the habit and appearance of the black-boy, growing 
- from twenty to thirty feet high, there are from fifteen to twenty 
flower-stalks on the same plant, each nearly eighteen inches 
ong; the flowers are borne in round heads, about two inches 
in diameter. With the Kingia, a pretty dwarf species of 
Banksia occurs ; the buds are oval, but the full-blown flowers 
_ and seed-vessels are round, the former are orange-coloured, 
inclining to yellow, the seed-vessels are covered with a rusty 
down, which distinguishes it from another round-headed 
kind found nearer the foot of the hills. In proceeding 
Straight from the Peninsula towards Wallup, the native name 
of a remarkable hill which lies about a mile to the west 
of the gorge of the Helena river, where it makes its way 
through the Darling range of hills, by what the settlers call 
the Rocky pass, we come to what are called the Guildford 
lakes, where some curious plants grow, particularly the two 
Species of Melaleuca, which the settlers term Tea-tree, and 
the natives Yumback; one of the species, seen only by fresh. 
_ Water, attains a diameter of six feet; the other, which is ob- 
_ Served sometimes in salt-marshes, grows about two feet—both 
kinds have their bark composed of numerous layers of cuticle, 
Something like that of the Birch. Of this bark, the natives 
construct their houses, whenever they can procure it con- 
venient to where they bivouac, which they generally do near 
Water. With the flower-stalks of the black-boy and the bark 
of the Yumback, they in a few minutes build a house per- 
 Teetly impervious to rain, and, with a fire in front, can re- 
gulate the heat to any degree they think proper. Several of 
, first Settlers’ dwellings were covered with this bark; I think 
Some of them still remain, at least they did so very lately. 
__ In the Guildford lakes, a beautiful aquatic Orchis prevails, 
flowering in the greatest perfection where the water is about nine 
Inches in depth; its blossoms are large, of a light blue colour, 
with deeper shades of the same colour. In this Orchis, the — = 
lower lip becomes contracted in the middle, and bears what I 
finely marked, and the inner divisions of the perianth spotted — —
