26 Historical Sketch of the Science of Botany [January, 
Some Greenland plants were described, 1770, by Rottboell, 
professor in Copenhagen, and, in the same year a history of 
Greenland was published by the missionary Cranz; the plants in 
it were described by Schreber. 
The largest collections were made in this century by yer 
Vahl, the librarian of the botanical garden in Copenhagen, who 
traveled nine years in Greenland, and probably there will not — 
many new discoveries be made. J. Lange’s catalogue of Green- 
land plants (in Rink’s work on Greenland, 1857), contains 320 ; 
species in 52 orders. 
A list of plants collected on the coast of Baffin’s bay was pub- — 
lished by Robert Brown, in 1819, and by the same a “Chloris — 
Melvilleana,” 1823, containing 131 species, of which 80 are phe- 
nogamous, collected at different times by Sabine, Edwards, Ross, 
Parry, Fisher and Beverley. 
Scoresby’s collection in East. Greenland, was described by 
Hooker in 1823, and that of Sabine in 1824. 
John Richardson, born in Scotland, 1787 (died 1865), was the 
naturalist of the expedition from the shores of Hudson’s bay to 
the Polar sea, 1823, under the command of Franklin. This — 
expedition started from York Factory, on Hudson’s bay, and | 
proceeded via Cumberland House, Carlton House, Fort Chippe- — 
way, on the Athabaska lake, Fort Providence, on the Slave lake, 
and Fort Enterprise, 65° N. latitude, to the Coppermine river, 
then along the coast eastward to Cape Turnagain, the Hood 
river up to Fort Enterprise, to Norway House, on the Winnipeg 
lake, and back to York Factory. The collection of plants con- : 
tained 700 species, and was published by Richardson in the 
botanical appendix to Franklin’s Narrative, printed 1823. 
The narrative of the discoveries on the north coast of America, — 
by Simpson and Dease, in 1837, published in 1843, contains a — 
catalogue of plants examined by Sir William Hooker, but noth- 
ing new; all the species were already collected by Richardson. 
Berthold Seemann (born in Hanover, 1825), the naturalist on 
board of Ai. M. S. Herald, udder the command of Captain H. 
Kellet, during the years 1845-1851, described, in a letter addressed 
to Sir William Hooker (in Journal of Botany), the arctic Flora of 
Kotzebue Sound, and published, 1852-1857, the botany of the 
expedition, the first part of which contains the Flora of Western 
Esquimaux land.
