1*4 COROLUFLOR^ 



2. Calluna {Ling, Heather) 



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 in 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. 



3. Menziesia 



1. M. ccerulea (Scotch Menziesia). Leaves numerous, linear, 

 minutely toothed ; flower-stalks covered with glandular hairs ; 

 flowers in terminal tufts ; corolla 5-cleft ; stamens 10. A small, 

 shrubby plant, naked below, very leafy and hairy above, with large, 

 pale purplish blue flowers. Very rare ; found on the " Sow of 

 Athol," in Perthshire, but " nearly, if not quite, extirpated by an 

 Edinburgh nurseryman " (Babington). Fl. June, July. Shrub. 



2. M. polifolia (Irish Menziesia, or St. Dabeoc's Heath). Leaves 

 egg-shaped, with the margins rolled back, white, and downy be- 

 neath ; corolla 4-cleft ; stamens 8. A small shrub, with large 

 purple, sometimes white, flowers, which grow in terminal, leafy, 

 i-sided clusters. Mountainous heaths in Ireland ; rare. Fl. June, 

 July. Shrub. 



4. Azalea 



1. A. procumbens (Trailing Azalea). A low trailing shrub, of a 

 very different habit from most of the garden plants cultivated under 

 the name of Azaleas. The stems are prostrate and tangled ; the 

 leaves small, smooth, and rigid, with the margins remarkably rolled 

 back ; the flowers are flesh-coloured, and grow in short terminal 

 clusters or tufts. Highland mountains. Fl. May, June. Shrub. 



5. Andromeda 



1. A. polifolia (Marsh Andromeda). The only British species, 

 growing in peat bogs in the north. A small leafy, evergreen shrub, 

 with slender stems, narrow, pointed leaves, and terminal tufts of 

 flesh-coloured, drooping flowers. Fl. June to August. Shrub.
