observed, to the tops of the adjacent mountains, have become changed 
to marble"; below Selwyn River, Yukon; Cape Nome, Alaska.’ 
Of the three Siberian stations of Gmelin two are definitely located 
on a geological map of Siberia, Olakminisk and Ochotsk, both in 
“ Paleozoic ” areas; and, most important of all, the type station in 
western China is “by the side of a stream rich in calcareous de- 
posits." 4 
Differing from the black-berried shrub in such essential characters:— 
the narrower and pointed inner scales of the winter-buds, the thinner 
and more elongate, more deciduous leaves without the characteristic 
bristly ciliation, the juicier scarlet berries and the smaller seeds, as 
well as its usual if not absolute restriction to caleareous soils; the 
scarlet-berried shrub has abundant claims to specific separation. 
Before formally transferring it, however, it is necessary to look into the 
generic name which it should bear. Its black-fruited relative of 
Eurasia and our northern and alpine granitic, gneissoid and siliceous 
areas was called by Linnaeus Arbutus alpina, but by practically all 
subsequent botanists has been treated as generically distinct from 
Arbutus, which has a many-seeded berry. 
The generic name Arctostaphylos Adanson (1763), though very 
inadequately defined, has been almost universally used for 4. alpina 
(L.) Spreng. (1825) and for A. Uva-ursi (L.) Spreng. and its allies, 
but recently Mr. F. N. Williams? has revived the Clusian and Tourne- 
fortian Uva Ursi on the basis of its post-Linnean use by Miller 
in the Abridgement of the Gardener's Dictionary in 1754, nine years 
before the publication of the generic name Arctostaphylos. The 
name or names, Uva Ursi, altered by Mr. Williams to Uva-ursi and by 
some others to Uva-Ursi has promptly been taken up by several 
authors to displace Arctostaphylos; but as Mr. B. Daydon Jackson 
well points out: “The proposed use of Uva Ursi for Arctostaphylos 
is excluded by analogy: Linnaeus (Phil. Bot. 160 (1751)) says:— 
‘Nomina generica ex duobus vocabulis integris ac distinctis facta, 
e Republica Botanica releganda sunt... .[e. g.] Vitis idaea T. Vacci- 
nium." * Not only is the name Uva Ursi excluded by analogy and

including Nome, is indicated as Paleozoic.
