unpleasant. (Don’s Mill, iii. p.836.) A trailing shrub, native of Den- 
mark, Switzerland, Dauphiné, Savoy, Siberia, &c. Found wild in many 
places of the Highlands of Scotland, in dry barren moors. Nothing is more 
common, says Linneeus, in all the Lapland alps, in Dalecarlia, from their 
tops to their bases, round the White Sea, especially in very sandy places. 
It is also found in Canada, and the more northern parts of America, 
inthe Aleutian Isles, &c. In British gardens, it has long been a favourite 
peat-earth trailing shrub, requiring an airy situation. It does not thrive in 
the immediate vicinity of London, nor where it is much sheltered; but, 
either on rockwork, in beds of dry peat, or in moist peat, it grows with great 
luxuriance, and occasionally ripens fruit.

Identification. Gaud, in Frez. Voy., p. 454. t. 67. ; Don’s Mill., 3. p. 836. 
Derivation. Named after Dom Pernetty, the author of the Account of a Voyage to the Falkland 
Isles ; a work remarkable for its interest, as well as for its candour and exactness. ‘The original 
species of this genus was mentioned by this traveller under the name of ‘‘ Bruyére a feuilles 
pointues,”’ (Lindi. in Bot. Reg. t. 1675.) 
Description. Evergreen undershrubs. Natives of North and South America.

Spec. Char., §c. Leaves ovate, cuspidate, denticulately serru- 
late, stiff, shining on both surfaces. Pedicels axillary, brac- 
teate, about equal in length to the leaves. Flowers white, 
drooping. (Don’s Mill, iii. p. 836.) A shrub growing to the 
height of from 2ft. to 3ft.; a native of Terra del Fuego, 
Cape Horn, and the Straits of Magellan. It was intro- 
duced in 1828, and flowers in May. In the garden of W. 
Harrison, Esq., of Cheshunt, in Hertfordshire it has, within 
3 years, formed an evergreen bush, 34 ft. in diameter, and 
24 ft. high, in a bed of peat soil. It is a hardy evergreen 
shrub, of considerable beauty, on account of the neat appear- 
ance and dark colour of its foliage. (Bot. Reg., May, 1834.)

Identification. Gard. Mag., 10. p. 286. ;*Don’s Mill., 3. p.837. ; Bot. Mag.,t 3177. 
Synonyme. A'rbutus pildsa Graham, Dr. Lindley says, “ As far as habit and the structure of the 
flowers are concerned, A’rbutus pildsa Graham would be referable to Pernéttya ; but we incline 
to believe that plant an Andrémeda” (Bot. Reg. t. 1675.) ; the doctor speaking of the genus An- 
dr6émeda as it stood previously to Professor Don’s division of it.
