BOTANY OF THE FXROES 4138 
Ostrup on the Diatoms from these Alge. by C. H. Ostenfeld on the 
Phytoplankton from the sea, and a joint p paper by Messrs. Bérgesen 
and Ostenfeld on that from the lakes; H. Di ahlstedt describes oe 
Hieracia, and Prof 
the history of the Flora. This last is of especial ‘interest to British 
botanists, and entirely supports the view—first promulgated, we 
believe, by Dr. Trimen and Mr. Newbould—that the Ferées would 
(apart from political cient be rightly included in the 
British Flor spy just as the Channel Islands should be excluded 
therefrom rof. Warming’s essay is too long to reproduce, even 
in part, and we must refer our readers to the book itself, which by 
Ww written in English ; he analyses the contributions of the 
a, a 
pally Great Br itai Elsewhere he says: ‘‘ Even on the basis of 
his very poor saiotiol N. Wille in 1897 (Botaniska Notiser) arrives 
at the conclusion that the flora should more particularly be charac- 
terized as a poorer part of the English flora, and that the forms 
agree very closely with those of Engla nd.” 
P. - Warming, says the flora, ‘‘ seen from a geological point of 
view,’’ is “a g flora,’’ having no endemic species of vascular 
plants except’ fa exception is significant—‘‘ among the Hieracia. 
These were entrus sted to Dablstedt for elaboration, and it will sur- 
prise no one who is acquainted with his published fasciculi—of new 
subspecies and aoe varieties of subspecies and new forms and new 
hybrids and ‘* modifications” (21 species 
and 2 varieties) are all endemic, though they are often closely _Te- 
f 
of the new forms are: ‘ , 1 speci some 7 varieties out 
of 338 species ; Vrekwitet ‘Aes i splat: Me varieties, and a few 
eerandaty forms out of 824 species; Freshwater Diatoms, 4 species 
ome 9 varieties out of 248 species; Fungi, 9 species out of 
168 species; Lichens, no new forms out of 194 species.’ 
We note that a third part, ¢ sostaia ines ‘‘ the papers on the vege- 
tation of land and sea,” is in preparation, it having been found 
impossible to conclude the work in two parts, as had been intended ; 
this “ will most likely be ready for publication in a year or two. 
The various contributions forming the pre resent volume have been 
‘‘ published” separately—the first containing the Marine Alg@ as 
long ago as November, 00 a fact which must not be overlooked 
in the citation of new nam 
It is to be regretted that i in a work of this kind some use should 
not be made of the tops of the pages, which might well indicate 
the subjects treated of below, instead of, as at present, containing 
nothing but the number of the page.
