Erica.] XLV. ERICACES. 288 
A genus of about 400 genuine species, besides the innumerable 
garden hybrids and varieties. Its geographical range is eminently 
Atlantic. The greater number of species come from south-western 
Africa, where co extend to the eastward. In Europe also Heuths 
are strictly western, with the exception of two or three species 
which extend eastward along the sandy wastes of northern Europe, or 
round the Mediterranean to the frontiers of Asia. The genus is other- 
wise unknown in Asia, America, or Australia. 
Anthers included wit! in the corolla. 
Corolla nearly 4 inch long, oblique at the mouth. Anthers 
without awns : . 8. &. ciliaris. 
Corclia about 4 inch long, straight at the mouth. Antlers 
with 2 awns, or little appendages at the insertion of the 
filament, 
Leaves 3 in a whorl. Flowers numerous, in oblong or 
elongated racemes . ‘ , ‘ p : é ‘ «ode By CLET ERR

1. E. cinerea, Linn. (fig. 637). Bell Pe it small bush. Leaves 
linear, finer and more pointed than in any of our other Heat's, and 
usually 4 in a whorl, with clusters of small leaves in their axils. 
Flowers numerous, of a reddish purple, in very showy, den-e terminal 
racemes. Sepals small and narrow. Corolla ovoid, about 4 lines long, 
straight at the mouth, with 4 very small lobes or teeth. Stamens 
enclosed in the corolla, with small toothed appendages at the insertion 
of the anther on the filament. 
Common in western Hurope, from southern Spain to Norway. Ranges 
over Britain, covering immense tracts of country on the Scotch, Irish, 
Welsh, and some English moors. fl. summer and autumn. 
2: E. Tetralix, Linn. (fig. 638). Cross-leaved H.—Generally a lower 
plant than &. cinerea, bushy at the base, with rather short, erect, 
flowering branches ; the leaves in fours, shorter and less pointed 
than in that species, and ciliate with short stiff hairs, besides a 
short whitish down, which often clothes the branches and upper 
leaves, Flowers about the size of those of &. cinerea, but more pink 
in colour, and forming little terminal clusters or close umbels. Appen- 
dages to the anthers entire, awnlike, and often nearly as long as the 
anthers themselves, 
A strictly western species in southern Enrope, but in northern 
Europe extends over Sweden and northern Germany to Courland and 
Livonia, but never so gregarious as FZ. cinerea. Ranges all over Britain, 
and very common in the west. Fl. summer, rather /ate. A very 
marked variety, with shorter and broader leaves of a darker green, 
from Connemara, in Ireland, and also from the Asturias, has been 
distinguished under the name of Macka’ana (Bab.) as a species, and 
was formerly adopted as such by myself, but the numerous inter- 
mediate specimens I have since seen induce me now to consider it 
as a mere variety. Intermediate forms between this and £. ciliaris, 
ebserved in Cornwall and Dorset, are natural hybrids.
