is seen, which I sent to London some years ago, and was 
informed that it constitutes a new Genus* belonging to the 
Natural Order Chamelauciee, of De Candolle. I have 
_ gathered nine or ten species of thesame Genus, most of them 
3 very beautiful. On the bank of the river, a few hundred yards 
.. above Mr Hardy’s house on the Peninsula Farm, a species of 
~ Xylomela grows, I suppose occidentale of Frazer. It is curious 
... toobserve the numbers of foreign plants that have established 
themselves on the Peninsula farm and about all the old settle- 
ments; affording a clear proof that man, when he emigrates, 
carries the weeds that are most troublesome in cultivated 
ground along with him. Here the Lolium temulentum and 
_ Several species of Wild Oats have taken exclusive posses- 
" sion of the lands first broken up for wheat; the elegant 
_ Briza minor and the Phalaris aquatica are two of the com- 
. Monest grasses on the farm; the Centaurea solstitialis is one 
_ 9f our chief pests; Polygonum aviculare is also very com- 
. Mon, but it is much relished by cattle. ‘There are several 
_ foreign plants that become troublesome weeds here, which 
| àre not known (at least as weeds) in England. I myself in- 
_ troduced the first Cape Gooseberry (Physalis Peruviana), and 
the first Solanum Capense, and in the short space of ten 
_ years they are perfectly naturalized; the Solanum lunatum 
we found on Garden Island when we arrived, but it has 
since made its way to the mainland, and is plentiful about 
— Perth. The English Sowthistle (Sonchus oleraceus) which now 
is the most annoying weed we have all over the country, even 
80 far as the York district, was quite unknown when we came 
here; the native Sowthistle, a far finer plant, growing eight 
or ten feet high, being at this time almost extinct about the 
settlements, The species of Casuarina called Swamp Oak 
by the settlers, produces on the Peninsula two kinds of 
Loranthus, one bearing hoary and the other green awl-shaped 
leaves. It is a curious fact that these parasites generally — — 
have some similarity to the trees on which they grow. Those —
