184 BOTANICAL INFORMATION. 
in its abundance of plants yielding woods, or otherwise in use ; it is sup- 
posed to amount to 500 species. Japan, with China, Korea, and Upper 
India, constitute that complicated flora, which is chiefly significant by 
such important productions as the tea shrub, the camphor, and varnish 
trees, and rice. The flora of Japan, however, is most intimately related 
to that of China. These empires, as well as Korea, have had intercourse 
with each other from time immemorial, and they have therefore the same 
plants in cultivation. But the flora of Japan connects itself also to that of 
c ge ern India and the Himalaya, by a great community of genera, 
a difference, and yet an affinity among the species. Another 
Xon is with the flora of North America; that is, with the Atlantic 
portion of it. Several genera (Negundo, Sassafras, Diervilla, Torreya, 
Pachysandra, Michelia, Maclura, Liquidambar), hitherto considered as 
the exclusive property of the new world, have been proved by the 
researches of our colleague, to exist also in the old world. There is a 
striking affinity or community between the plants of the northern por- 
tion ofthe Japan Islands, and south-eastern Siberia and Kamtschatka. 
The flora of Japan has but a feeble relation to that of South America, 
and none at all with Africa and Australia; while not a small number of 
its genera occur also in Europe." 
Professor von Martius has entered into full details of the many and 
varied other labours of his colleague. They were scientific and profound, 
as well as practical and useful, in an eminent degree. Among the latter, 
are remarks inserted in the Bulletin of the Royal Academy of Bavaria, 
for Aug. 1835, on Dr. Royle's * Botany of the Himalayan Mountains,” 
a work which contains a vast mine of information, requiring, in my humble 
judgment, only to be republished in a cheaper form, incorporating with 
it the additional materials in the “ Productive Materials of India,” of 
the same author, to obtain that degree of public usefulness, and full 
appreciation, to which it is so eminently entitled.—At the conclusion 
a list is appended of all the new genera established by the deceased in 
von Martius's **Nova Genera," in the works on the flora of Japan, 
and on other occasions. 
The subject of the Eloge was born at Munich on the 10th August, 
1797, from distinguished parents. He died on the 18th February, 
1848. He dedicated himself in 1819 to botany under the tuition 
chiefly of his predecessor at the Botanie Garden at Munich, the celebrated 
Nestor of the science, Francis von Paula Schrank, * rei herbariz in
