c Appendix A. 
the number of species described is 2,500. The only aid received 
was from Dr. Boott, who worked up the Carices (158 species). 
1830. The British Flora, comprising the Phaenogamous or 
Flowering Plants and the Ferns, by Sir W. Jackson Hooker, 
LL.D., &c., 8vo. In the first edition of this work the Linnean 
system was adopted, followed by an Appendix on the Natural 
Orders. About 1,570 species are included. The second edition 
was published in 1831 ; the third in 1833, in two parts: Part I. 
Flowering Plants and Ferns, with four plates, containing analyses 
of eighty-two species ; Part II. Cryptogamic Plants, also formed 
vol. v of Sir James Smith’s ‘English Flora.’ This part did not 
accompany any future edition of the ‘ British Flora.’ It appeared 
in two volumes, one, in 1833, comprising the Mosses, Characeae, 
Hepaticae, and Lichenes, by the author, and the Algae by Greville 
and Harvey ; the other, in 1838, on the Fungi, is by the Rev. 
M. J. Berkeley. The fourth edition appeared in 1838 ; the 
succeeding four were issued from Kew. The fifth, in 1842, 
is the first in which the arrangement is throughout by Natural 
Orders. The sixth, in 1850, and succeeding, are by W. J. H. 
and G. A. Walker- Arnott, with twelve plates, containing the 
analyses of 118 species. The seventh appeared in 1855; 
the eighth and last in i860; it contains about 1,636 species, 
or about sixty-six more than did the first edition published 
twenty-five years earlier. 
1830. An Encyclopaedia of Geography, by Hugh Murray, 
assisted by the following gentlemen in their respective depart- 
ments of Science : — William Wallace, Robert Jameson, W. J. 
Hooker, William Swainson. This is a ponderous 8vo volume 
of 800 pages, with eighty-two maps and upwards of 1,000 
miniature woodcuts. My father contributed about 180 slight 
articles on the botany of thirty-seven countries or groups of 
countries, with about 220 woodcuts of plants by Fitch. In 1835 
H. C. Watson contributed a paper to the ‘Companion to the 
Botanical Magazine,’ vol. i, p. 228, entitled ‘Botany of Great 
Britain,’ pointing out omissions and errors. A second edition 
appeared in 1840, ‘ thoroughly revised and brought down to the 
present time,’ in which, however, the omissions and errors indicated 
by Watson in the first edition are not corrected. My impression
