LETTERS FROM DR. HARVEY. 47 
Botanists? They are very abundant here; I think I could certainly get 
150 species, probably more. I have indeed begun to collect specimens 
enough for twenty to twenty-five sets, and as I do this in my morning 
walks, which, without some such object, would become very irksome, 
there will be nothing lost if it will not succeed; if however you think 
it would do, I should feel much obliged if you would be my agent 
in the matter, and make the necessary announcements, for I should 
think it would be best to send home the first hundred or so, as soon as 
collected ; in the meantime I will go on for my own amusement. The . 
collection of Mosses, Hepatice, and Lichens which I am making, ac- 
cumulates slowly, as there are but few species, and those not easy 
. to get in fruit, but I keep adding one now and then: they now 
number about twenty species, but all are good specimens in a good 
state.—J. M. 
Extracts from Australian Letters of Dr. HARVEY.

Madras Steamer, off Melbourne, Sept. 5, 1854. 
I send you by post a paper by Drummond, on the Botany of the 
Northern Districts of the Swan River Colony [this has appeared in our 
Journal, vol. v. p. 115], and characters of certain new genera, which - 
he requested me to examine and describe. The poor man feels rather 
sore that so many new genera should first have appeared in Preiss's 
book, which had been sent home by him (Drummond) years before © ee 
Preiss visited the Colony; so I am anxious to preserve for him any - 
little gleanings that may remain. The most curious of the genera de- — 
scribed by me are the Rutaceous ones; and what I have called Dicra- 
stylis, which appears to me to be either a Cordiacea with opposite — 
leaves, or the type of a new Order, between Cordiacee and Verbena- | 
cee. I suppose you will find specimens of all in your last set of Drum- 
mond’s plants. I hope you will allow Drummondita to stand, as D. feels — 
rather uncomfortable in there being no universally acknowledged genus 
bearing his and his brother's name. He himself selected and proposed 
this plant for a “ Drummondia;" but with your genus of Mosses staring 
me in the face, I had to alter the name. 
I returned from Swan River to King George's Sound the beginning 
of August, and sailed for Melbourne on the 29th. We expect to 
anchor tonight before midnight. I wrote you from Fremantle in Mar
