1 84 COROIXIFLOR^ 



2. Calluna {Ling, Hecdher) 



I. C. vulgaris (Ling, or Heather). — The only species. A strag- 

 gling, branched shrub 1-3 feet high. The leaves are very small, 

 more or less downy (sometimes even hoary), and arranged m four 

 rows on opposite sides of the stem. The corolla is very small and 

 bell-shaped, and is concealed by the rose-coloured calyx, at the base 

 of which are four small green bracts, which have the appearance of 

 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 Cornwall, with double flowers ; and white specimens, which are 

 not unfrequent, are supposed to bring the finder good luck. Heaths 

 and moors ; abundant. — Fl. July, August. Shrub.
