4. South American, corresponding with the Neotropical 
region of Zoologists. 
5. Australasian, corresponding with the Australian 
region of Wallace and Sharpe, less the Austro-Malay 
sub-region, and with the Pacific and Australian region 
of Sclater, less the same sub-region. 
Hemsley’s alternative primary division, which he says is 
more in accordance with the writings of many botanists, is as 
follows :— 
. Northern Region. 
. Neotropical. 
. Paleotropical. 
. Andean. 
. Cape. 
» Australasian.

In both his divisions he omits two small but exceptionally 
interesting floras, namely, those of the Sandwich Islands 
and Antarctic regions, which though not large enough to be 
treated as primary regions, cannot be consistently included in 
either of the others. 
Sir Joseph D. Hooker in reviewing Hemsley’s arrangement 
on pages lxy.-lxviii. of the same work, states that though he 
disputes neither his facts or his methods, yet he differs from 
him to some extent in his limitation of the primary floras 
of the globe, and divides the world into two primary regions 
or Botanical Empires, Tropical and Temperate, which he 
again divides into the following regions or Botanic King- 
doms :— 
1. The North Temperate region of the Old World. 
This coincides with the Palearctic region of Sclater, 
except that it includes Greenland. 
. The North Temperate region of the New World. 
. The Tropical region of the Old World. 
. The Tropical region of the New World, 
. The South Temperate region of America, 
. The South Temperate region of Africa. 
. The South Temperate region of Australia.
