ERICACEAE. 35 



in terminal umbellate racemes. Pedicels longer than tho corolla, 

 without bracteoles. Calyx deeply 5 -cleft. Corolla 5-toothed. 

 Stamens 10 ; anthers obtuse at the base. Plant sub-glabrous, except 

 the peduncles, calyx-segments, and capsule, which are clothed with 

 gland-tipped hairs. 



On heathy moors. Very rare. On the Sow of Atholl, in the 

 North of Perthshire, where it was believed to be extinct, until 

 Professor Balfour rediscovered it in 1803. 



Scotland. Shrub. Summer. 



A small much-branched shrub, with the stems rarely above 

 G inches high, decumbent at the base. Shoots of the year glabrous. 

 Leaves crowded, spreading. Pedicels f to 11 inch long. Flowers 

 drooping, about -| inch long, pinkish-lilac. 



Of this plant I have not seen British specimens in flower or 

 fruit. 



Yew-leaved Menziesia. 



Ttibe III.— EBICEiE. 



Corolla persistent, withering. The flower-buds not combined 

 into scaly inflorescence-buds. 



GENUS VII— ERICA. Linn. 



Calyx free from the ovary, 4-cleft or -partite. Corolla hypo- 

 gynous, persistent and withering, nionopetalous, oval- or globose- 

 urceolate or cylindrical or bell-shaped, with 4 erect or spreading 

 or revolute teeth, or more rarely 4 lobes. Stamens 8, included 

 or inserted ; filaments free ; anthers often with 2 awns or crests 

 at the base, opening by 2 pores or chinks at the apex. Emit a 

 capsule, with 4 cells opening loculicidally by 4 valves breaking 

 away from the central placental column, to which a portion of 

 each dissepiment remains attached, while the remaining portion is 

 borne down the middle of the valve. Seeds very numerous. 



Shrubs, generally much branched, with linear verticillate or 

 more rarely alternate rigid evergreen leaves, and usually drooping 

 flowers, variously disposed, generally showy. 



The name of this genus of plants is derived from the word cporu (ereiko), I break, 

 from the idea that some of the species destroy the stones formed by lithic acid in the 

 human body.
