242 Notice of Dr. Hooker’s Flora of New Zealand. 
his Flora, including upwards of a hundred of the lower Crypto- 
gamia of which the materials are in too imperfect a state for 
satisfactory determination. This is more than double the number 
the attention which has been devoted to the lower orders. 1S 
may be easily shown ; for, whereas in all the earlier enumerations 
and collections the number of Flowering plants exceeds the Flow- 
erless, in M. Raoul’s catalogue they are equal, and in the present 
work the relative proportions at ; 
plants being to the Cryptogamic as 1 to 1:6, i. e. about two to 
three.” As to the probable ratio of the known materials to th 
whole flora, Dr. Hooker remarks that “the islands have been 
botanized upon by upwards of 35 individuals, whose specimens 
have (with a few unimportant exceptions) all passed under my 
eye. The flora of the Northern Island has been tolerably well 
examined, so far as its flowering plants are concerned; thoug 
there remains a good deal to be done on the west coast, especially 
in the neighborhood of Mount Egmont. Dr. Lyall alone has 
collected on the Southern Island, and on the west coast north of 
Dusky Bay. The Middle Island has been visited by few explorets; 
its north and east coasts alone having been botanized: the west, 
and the whole mountain range require a careful survey ; and, ¢on- 
sidering how many Auckland and Campbell Islands’ plants are 
still strangers to New Zealand, it cannot be doubted that much 
remains to be discovered there. Excepting from the above men- 
plants, for the following reasons: 1. There is a remarka 
sameness in the flora throughout large tracts, (in which res} t 
New Zealand contrasts remarkably with Tasmania); 2. Because 
out of the 730 flowering plants known, there are scarcely one 
hundred that have not been gathered by several individuals ; 
3. Because the collections I have lately received, though some 
them are extensive, and from scarcely visited localities, bind 
tain little or no novelty. With Cryptogamia the case is W1@®. 
different ; and it is difficult to estimate the vast number, especially 
of Mosses, Hepatic, and Fungi, that will reward future explot- 
ers in what, as far as Flowering plants are concerned, are eX 
ted fields.” From the data now possessed, and from a compariso™ 
of the same with the flora of better known countries, Dr. . ae 
ventures the opinion that there are not more than 4000 species:
