often looked for this season. We have added five or six to 
our list, one that I have found is a splendid species of Mr 
Brown’s Caladenia which grows two feet high, the three outer 
divisions of the perianth are more than two inches long, 
the two side ones shorter, of a yellow colour variegated with 
red, they are sickle-shaped and turn round their points, so 
that they act as a sort of guard to the lower lip, which moves 
on a hinge. In this species the lower lip is heart-shaped, 
with a dark purple curled insect-like point; the throat is 
filled with purple glands, the two sides smooth and yellow; 
When undisturbed, the lower lip lies up against the anthers 
until after impregnation, but when the plant is moved a little 
to one side it falls down. Another, which I have gathered 
this year for the first time, is a Pterostylis, which I have 
 hamed P. rupestris, from its growing in the crevices of horn- 
blende rocks, where there is scarcely any earth; it bears four 
or five flowers, and has the stem covered all the way up with 
sheathing scales; the lower lip moves as in the Pterostylis 
Which inhabits the limestone rocks on the coast. A third 
Urchis, also detected this season, forms a different genus from 
any we had seen before; its lower lip resembles an insect, 
and assumes the appearance of a head and feet, which none 
of the other insect-like Orchidez have. The other Orchidee 
found this season are small; they were gathered by my 
youngest son when out kangaroo-hunting. I have only seen 
them in a dried state. This is now the gayest season of the 
Jear at Swan River; the grasses are mostly in flower, the 
birds are breeding, and singing from daybreak in the morn- 
ing until dark; the grassy districts are covered with the 
Pink, yellow, and white Everlastings, and other annual plants 
Of this class. There is a curious little plant now in bloom, 
Which I think is nondescript; (I have since met with two 
‘More of the same genus;) I suspect it belongs to Mr 
Brown's genera Aphelia or Devauzia,and in a natural arrange- —— 
Ment will be placed near the grasses; it has a few seta- —— 
ceous leaves like a very small grass, and from twenty to t| a 
flower-stalks about an inch high; the head of flowers bears —
