230 MR. W. B. HEMSLEY ON THE 
The preceding summary of the Himalayan Flora from 15,000 ft. 
and upwards was compiled by Mr. Pearson from Hooker’s ‘Flora 
of British India,’ and can only claim to be a very rough approxi- 
mation, whether as affecting the author or ourselves. It is 
sufficiently correct to afford a basis for comparisons, a few of 
which are given :— 
Orders. Genera. Species. 
Himalaya .......... 38 149 470 
Tibet ..........08.. 41 119 283 
This brings out the fact that the poorer Flora in species is the 
vicher, relatively, in genera and orders, which is in accord with 
most poor Floras, and especially with those of remote Oceanic 
Islands. 
Generally speaking the natural orders are the same in both 
Floras, and the preponderating orders likewise; but the follow- 
ing are not in our collections from Tibet :—Berberidacez, 
Violacez, Valerianacez, Ericacez, Conifers, and Orchidacew. Of 
course no importance can be attached to this circumstance. It 
is interesting to compare this general summary of the Himalayan 
Flora with that of Hobson’s Yatung collection, afew pages back, 
especially the relative increase of Leguminose and Composite 
at the higher level.
