ON THE DISTRIBUTION OF PLANTS. 385 
By way of illustrating what is being done abroad in this subject, I 
. may be allowed to give t the fo ollowing extraets from papers by Professor 
oe x Florence, on the a oue of the Distribution of Plants 
and Animals. Not being, unfortunately, versed in Italian, I have had 
recourse a Professor Hilde ete abstract of the ee * Bo- 
tanische Zeitung’ for November 19th and 26th, 1869 
* Every one must have observed that the flowers va = — 
lants, in contradistinction to those of our species of un 
endowed with very bright handsome colours. Especially is ‘scarlet lih 
in the flowers of our latitudes, ut so we or only doe e en 
ce, a oh memi secretion of ne ectar. This ast circumstance, in 
* In general the dimensions of flowers correspond to the size of the 
pollenizing animals. For instance, the pollenizers possessed of the 
largest stature in Europe are the sphinxes (Deilephile), and certain

Pancratium maritimum and Convolvulus sepium s Mili to 
nm observations, the two y last are actually "fertilized by Deilephila

we tam from the tropics to aum rn uin a po decrease

especially those which are Lue fertilized by Trochilidze. Peonia 
d roses must cease where Cetonie are no longer — d Eu

lepidoptera fail. = the arctic zone those ab ss ers only survive which are

Delpino then gives a very interesting "list of the flowering plants of 
Spitzbergen and Nova Zembla with reference to their special fertilizers in 
ose northern regions dium 
is most interesting and valuable study is one from which dwellers in 
towns are almost entirely shut out, but I hope that some of our cou end 
2 will take it up, and give us the result of a little close and care
