Erica. | XLV. ERICACEZ. 285 
Mackaiana (Bab.) as a species, and was formerly adopted as such by myself, 
but the numerous intermediate specimens I have since seen, induce me now 
to consider it as a mere variety. Intermediate forms between this and Z. 
ciliaris, observed in Cornwall and Dorset, are natural hybrids. 
3. B. ciliaris, Linn. (fig. 637). Ciliated Heath.—A very handsome 
species, readily known by its raceme of highly coloured rosy flowers, of the 
size of those of Menziesia polifolia. It isa straggling shrub, ciliated with 
short stiff hairs. Leaves.3 ina whorl, ovate, Flowers in short pedicels in 
the axils of the upper leaves. Sepals small and ciliate. Corolla about 5 
lines long, with a small, very oblique, 4-lobed mouth, Stamens enclosed in 
the corolla, without any appendages to the anthers. 
A strictly western species, on the continent confined to West France, 
Spain, and Portugal. Also found in Cornwall, and Dorsetshire. 7. early 
summer. 
4, G.carnea, Linn. (fig. 638). Mediterranean Heath.—Leaves in 
fours or rarely in threes, linear but obtuse, firmer and thicker than in Z£. 
cinerea. Flowers axillary, forming leafy racemes either terminal or below 
the ends of the branches. Sepals linear-lanceolate and coloured. Corolla 
narrow-ovoid, about 3 lines long, of a reddish flesh-colour. Anthers 
protruding slightly from the mouth of the corolla, oblong, inserted by their 
lower ends on somewhat flattened filaments, without appendages. 
The geographical range is different from that of most Heaths, being 
scattered here and there on the lower hills along the great central range of 
European mountains, from Switzerland to the Balkan, where it is usually, 
but not always, a rather low, almost straggling shrub. Descending to the 
shores of the Atlantic it is there more erect, with rather smaller flowers, a 
form considered by many as a distinct species, under the name of #. Medi- 
terranea, Linn. It reappears in boggy heaths of Mayo and Galway in 
Ireland, in a form intermediate between the extreme Continental varieties. 
It is not wild in Great Brita but frequently cultivated. FV. early spring. 
5, EB. vagans, Linn. (fig. 639). Cornish Heath.—A rather low 
species, the leaves linear, in fours or sometimes in threes, as in EZ. carnea. 
_ Flowers very numerous, axillary, on slender pedicels, forming terminal, 
oblong or elongated leafy racemes. Sepals short and obtuse. Corolla 
pink or almost white, rather small, campanulate when it first expands, but 
becoming nearly globular. Anthers very small, appearing double, protrud- 
ing beyond. the corolla upon slender filaments, without appendages. 
A gregarious species, often occupying large tracts of open country like 
Ht. cinerea ; ranging all round the Mediterranean from Spain to Greece, 
Turkey and Egypt, and ascending along the Atlantic to Cornwall, but 
never penetrating very far inland. FU. summer, rather early.

VIII. CALLUNA, LING. 
A much branched, low shrub, with minute, imbricating, decussate leaves, 
and axiliary small pinkish flowers, with 2 pairs of small bracts at their 
bases. Flowers as in Hrica, but the calyx is as long as the corolla, which 
is cleft to the base into 4 segments, and the capsule opens by slits opposite 
the partitions. Cells one or two seeded. 
[The solitary species of Calluna was included under Zrica in former
