BOTANICAL INFORMATION. 301 
granite rocks covering several acres, where, in pools of rain- 
water among the hollows, Mr. Gilbert discovered a small 
but curious fresh-water shell. I gathered a small species of Sty- 
lidium and a remarkable dicecious shrub with pinnate leaves, 
also new to me. The beautiful lace-like kind of Reindeer 
moss grows plentifully on these rocks, (Cenomyce retipora, 
Hook. Lond. Journ. of Bot. vol. I. Tas. X.) 
At the distance of about ten or a dozen miles from Cap- 
tain Scully’s residence we reached a. permanent spring, 
called Yoolgan by the natives, where there is excellent grass, 
of which we took advantage for the horses, while we halted 
and refreshed ourselves. On pursuing our journey, we found 
the way, as far as the Moore River, distinctly tracked by the 
carts and horses of my son's party, which had preceded us. 
Soon after leaving the spring we met two gentlemen, returning, 
forthey had been a day too late to join the others, so we knew 
it was useless for us, still farther behind, to hurry forward. 
Ten or twelve miles farther, we came to a Tea-tree swamp, 
called Yeinart, where good grass and water are to be found 
all the year round, and here we encamped for the night. 
‘Rain came on, but, fortunately, not heavy till daylight, for 
we had been too tired to do much in the house-building way 
in the evening, but the weather becoming decidedly wet, we 
quickly erected a shelter, which we covered with Tea-tree 
bark and rendered it waterproof, for nothing can be accom- 
plished in collecting during rain, and provisions are sure to 
be spoiled by exposure to it. In the afternoon we visited a 
Swamp, where one of my sons had shot several specimens of 
a small and beautiful Kangaroo, the native Marmine ; its fur 
is dark and tipped with longer silvery hairs. We saw plenty 
. of its marks, but could not detect a single animal. On the 
top of a hill grew two very distinct species of Dryandra, 
new to me, The first, (No. 41 of my collection), has acerose 
leaves about 2 of an inch long, and generally undivided, but 
in young and luxuriant plants they sometimes have one or 
two recurved teeth. This shrub generally grows 2 or 3 feet 
high ; its many branches forming a sort of level top. The
