guished from Z. T'étralix by the glaucous deep green hue, and 
deep purple, or sometimes -white, flowers. (Don's Mill., in. 
p. 795.) A shrub, growing from Gin. to 1 ft. in height; a 
native of Europe, but not in the south, nor in the extreme 4. 
north: beautiful in Britain. It is the badge of the clan ¥ 
Macalister.

Spec. Char., §c, A tree-like shrub, with tomentose branches. Leaves 3—4 
in a whorl, linear, glabrous. Flowers axillary, racemose, glabrous. Brac- 
teas remote from the calyx, Corolla bell-shaped, 2 lines long, white. An- 
thers crested. Style prominent, (Don’s Mill., iii. p.794.) A native of 
the south of Europe. Introduced in 1658, and growing to the height of 
from 10 ft. to 20 ft. in the Pyrenees, In Britain, this species is generally 
considered somewhat tender; nevertheless, in sheltered situations, it 
endures the open air, as a standard, in the climate of London, and is only 
killed down to within a short distance of the ground, in the most severe 
winters; and this, we believe, is more owing to the moisture of the atmo- 
sphere in autumn, and the sudden changes from frost to sunshine in spring, 
than to lowness of temperature. In the Pyrenees this shrub is found grow- 
ing among pine woods along with the arbutus, the myrtle, &c., and we have 
no doubt whatever, that it would thrive perfectly well in the pine woods in 
England; for example, those in the neighbourhood of Esher, on the Clare- 
mont estate, and those at Woburn Abbey. There are plants at Syon 12 ft. 
high ; one in the Edinburgh Botanic Garden, as a standard, 5 ft. high, and 
against a wall, 16 ft. high. 
Varieties. 
# E. a. 2 stylosa. — Style vay long. (Don’s Mill.) 
# E. a. 3 squarrosa Hort. — Leaves squarrose. (Don’s Mill.) 
# E. a. 4 minima Hort. — Plant small. (Don’s Mill.) 
The succeeding sort might be added as another variety ; but we have fol- 
lowed Don’s Miller in giving it in the form of a species. 
# 4, E.(a.) PoLyTRICHIFO LIA Sal. The Polytrichum-leaved Heath. 
Identification. Sal. in Lin. Soc. Trans., 6. p. 329.; Don’s Mill., 3. p. 794. 
Synonyme. Perhaps only a variety of EZ. arborea (Don’s Mill., 3. p. 794.) Dr, Lindley has inciden- 
tally,expressed, in Bot. Reg., t. 1698., as his opinion, that the Z. arborea styldsa of English gardens 
‘ is the EZ. polytrichifolia of Salisbury. 
Spec. Char., §c. Stem tomentose. Leaves 3—5 in a whorl. Flowers ter- 
minal. Bracteas remote from the calyx. Calyxes gradually narrowed at the 
base. Corolla 1—2 lines long. Spurs of anthers cuneated. Fruit pear- 
shaped. (Don’s Mill., iii. p. 794.) A native of Portugal, about Lisbon, 
and rather more tender than the species. It is to be found in some collec- 
tions; but when it was introduced is uncertain.
