ON THE FLORA OF LIBERIA. "79 
Geographical Distribution.—Five Roses are found south of 
the Tropic of Cancer, viz.: A. moschata and R. sancta in Abys- 
sinia, R. Leschenaultiana in the Neilgherries, and R. mexicana 
and R. Montezume, H. B. K., in Mexico. The latter is only a 
form of R. canina, so probably it has been introduced. In the 
North Temperate Zone there are six well-marked Rose-regions, 
a considerable proportion of the species inhabiting each being 
endemie. These are:—(1) Europe, including North Africa; 
(2) the Orient, excluding the European eountries included in 
Boissier's * Flora Orientalis"; (3) Northern and Central Asia, 
including China and Japan; (4) India; (5) Western United 
States and Rocky Mountains; and (6) the Eastern United 
States. Of these districts the richest in Roses is Europe with 
North Africa, which has 29 species. North and Central Asia, 
including China and Japan, closely follows it, with 26 species. 
The other districts have much smaller numbers—the Asiatic 
portion of the Orient having 18, India 9, the Western United 
States 10, and the Eastern United States 6 species. 
Contributions to the Elora of Liberia. 
By Dr. Orro Starr, F.L.S. 
[Read 16th March, 1905.] 
Tu subject of this paper includes a number of new species, some 
of them belonging to new genera, which were collected by 
Mr. Alexander Whyte in the Republic of Liberia during several 
expeditions undertaken by him last year on behalf of Sir H. H. 
Johnston acting for the Monrovian Rubber Company. As I 
wish to confine myself in this place to technical descriptions of 
the novelties in Mr. Whyte's collections, I abstain from an 
attempt to give a general account of the flora of Liberia, 
reserving that for another occasion. It may suffice to say that 
the collections were made in the following localities :— 
(1) At Monrovia and in its vicinity, within a radius of 6 miles, 
in February during the dry season, the ground being described 
as covered with second forest-growth on abandoned farms, and 
as flat with many lagoons and backwaters.
