398 ERICACEAE. 



but growing in a more bushy manner, with broader 

 leaves, and more numerous heads of smaller flowers. 

 Cunnemara, Ireland. E. Mediterrdnea (Mediterranean 

 Heath), well known as a garden plant, but found, also, 

 in Cunnemara, well marked by its coloured calyx ; and 

 E. cilidris (Ciliated Heath), by far the most beautiful 

 of all the British species ; the leaves are 4 in a whorl, 

 and the flowers, which are bright purple and half an 

 inch long, grow in terminal, interrupted, spike-like 

 clusters. It is found only near Cape Castle, Dorset, and 

 in Cornwall, where, though of local occurrence, it is 

 occasionally as abundant as E. cinerea is elsewhere. 



2. CALLUNA (Ling, Heather). 



1. 0. vulgdris (Ling, or Heather). The only species. 

 Heaths and moors ; most abundant. This was placed 

 by Linnaeus in the genus Erica (Heath) ; later botanists 

 have, however, made of it a distinct genus, and not 

 without reason. The leaves are very small, more or 

 less downy (sometimes even hoary), and arranged in 

 4 rows, on opposite sides of the stem. The corolla is 

 very small, and bell-shaped, and is concealed by the 

 rose-coloured leaves of the calyx, outside which are 

 4 small green bracts, which appear to form a second 

 calyx. The flowers remain attached to the plant long 

 after the seed is ripe ; indeed, it is not at all unusual 

 to find plants in full bloom with the withered flowers of 

 the preceding year still adhering to the lower part of 

 the stem. A beautiful variety has been found in Corn- 

 wall, with double flowers. FL July, August. Shrub. 



3. MENZIESIA. 



1. M. coerulea (Scotch Menziesia). Leaves nume- 

 rous, linear, minutely toothed ; flower-stalTcs covered 

 with glandular hairs ; flowers in terminal tufts ; corolla 

 5-cleft ; stamens 10. Very rare; found on the "Sow
