350 Notice of Dr. Hooker’s Flora of New Zealand. 
and of its numerous Australian congeners, with the single exception of 
Clianthus, of which there are but two known species, one in Australia, 
and the other in New Zealand and Norfolk Island. 
The rarity of Proteaceae, Rutacee, and Stylidee, and the absence of 
Casuarina and Caillitris, of any Goodenia but G. littoralis (equally 
found in South America), of Tremandrea, Dilleniacee, and of various 
genera of Monocotyledones, admit of no explanation consistent with 
migration over water having introduced more than a very few of the 
plants common to these tracts of Considering that Eucalypti 
form the most prevalent forest feature over the greater part of South 
inhabit New Zealand, none favor such a theory; one, Clianthus, I have 
just mentioned ; the second, Edwardsia, consists of one tree, identical 
with a Juan Fernandez and Chilian one, and unknown in New Hol- 
land ; and the third genus (Carmichelia) is quite peculiar, and consists 
of a few species feebly allied tosome New Holland plants, but exceed- 
ingly different in structure from any of that extensive Natural Order. 
Dr. Hooker then appends a carefully prepared table of 228 
phznogamous species which may be said to represent each other 
in two or all the three South temperate masses of land, viZ., New 
Zealand (including Auckland and Campbell’s Islands), Australia 
(including Tasmania), and extra-tropical South America, 
ding the Falkland Islands ; the list being confined to cases of 
real and usually very close botanical affinity, to the exclusion of 
analogical resemblances, however striking. The list is by no 
means overstrained, nor as full as it might be; since one oF two 
more good instances have occurred to our memory while looking 
over its columns. On comparing together the Australian i 
New Zealand columns, we find only fourteen blanks, not fille 
by known representative species ; a similar comparison of the 
New Zealand and South American columns shows forty-s 
blanks, sixteen of which are among the Endogens. —__ 
On fairly weighing all this testimony, the botanist will os 
h 
accede to our author’s conclusion,—viz., that the floras 0 
three great areas of land in southern latitudes ‘“ exhibit a e 
ical relationship as strong as that which prevails throughout de 
ands within the Arctic northern temperate zones : ich 8
