late in the eighteenth century. He became much interested 
in the flora of that country, and the results of his observations 
are recorded in an article published in 1803 with notes by 
the well-known botanist Willdenow. How many of Rottler’s 
lants, which were collected between Trankenbar and 
Satan are in the Bernhardi herbarium it is ee to 
say, but one of them, a plant collected on the 25th of Sep- 
tember, 1799, the original or type specimen of Trianthema 
triquetra, has been found. 
It has been a pleasure also to find another early collection 
of plants from India in the Bernhardi herbarium, namely, 
that of Wallich from the independent state of Nepal. In 
connection with these collections from the far east that of 
Robert Fortune should receive more than passing mention. 
Mr. Fortune collected extensively in China, particularly in 
the maritime province of Fokien, and his collections to a 
very great extent form the basis of an excellent flora of China 
by two well-known English authors, Forbes and Hemsley!. 
The flora of Australia is represented in the Bernhardi 
herbarium by a large series of specimens collected by Preiss 
in 1840 and also by plants distributed through Sieber at 
about the same time. The Preiss plants were critically 
studied by Lehmann?, and a detailed account of them was 
published in two octavo volumes: Both these collections are 
repeatedly cited in the standard work on the flora of 
Australia by Bentham and Mueller?. 
Botanical exploration in South Africa at no time has been 
more actively pursued than during the period to which has 
been referred. Thunberg* was one of the first to explore 
the country botanically, and his collections served as the 
basis for one of the early floras published of the Cape region. 
Perhaps the largest individual collection of South African 
plants ever brought together was by J. F. Drége, an assiduous 
collector, between the years 1826 and 1834. His collections 
are said to have numbered some 200,000 specimens, includ- 
ing many duplicates. From 1829 to 1850 Ecklon and 
Zeyher were engaged in botanical exploration in South 
Africa, and their collections also amounted to many thou- 
sands of specimens. All these collections, as well as those 
of Krauss and of Sieber, are copiously represented in the
