UPON THE BRITISH FLORA. 15 



I. Erica lusitanica, Rudolph (1799), non. Lin. E. arborca, 

 Brot, non. Lin., ex-parte (1804). E. polytrichifolia, Salisb. 

 (1802). E. codonodes, Lindl. Bot. Reg. t. (1698). Inflorescence 

 forming a panicle from eight to twelve inches long, peduncle 

 shorter than the corolla, which is sub-campanulate, constricted 

 at the base, pale rose-colour, and larger than that of E. arborea, 

 Lin., longer than the divisions of the sepals, anthers furnished 

 with two equally long filiform hairy appendages, ovary glabrous ; 

 leaves verticillate, linear, involute, glabrous, with minute setae, 

 branches upright, stem greyish, downy, composed of simple 

 hairs ; stem from 3 6 feet high. Perennial, flowering as late as 

 November and January. It grows vigorously on the lovely 

 grounds of Lord Eustace Cecil at Lytchett Heath, spreading 

 itself considerably from year to year, and seeding freely. I hope 

 next year to ascertain the limits of its extension. 



Hab., Lytchett Heath, England, and La Teste de Buch, near 

 Bayonne, France. These are its only recorded stations outside 

 the Spanish Peninsula, where there are records of it from Bilboa 

 in the north ; the mountains of Castile, Central Spain ; and two 

 in Andalusia; four in Portugal. The above census is taken 

 from Colmeiro's splendid " Topographical Catalogue of the 

 Plants of Spain, Portugal, and the Balearic Isles," consisting 

 of five royal octavo volumes of 3,419 pages. 



Erica lusitanica is closely allied to E. arborea, from which it is 

 difficult to be distinguished, they differ, however, sufficiently to 

 justify a specific separation. E. arborea differs in the stem and 

 branches being clothed with woolly down, composed of short 

 and long hairs, the long hooked and branched, the flower-bearing 

 branches shorter than those of E. lusitanica, the stems and 

 branches of which are less profusely downy, and furnished with 

 setae. 



E. arborea is abundant throughout the Spanish Peninsula from 

 the sea-level to the altitude of more than 1,000 feet. It is 

 found in every province from north to south, and, taking 

 Colmeiro's list as a guide, it appears to have a wide distribution. 

 It grows on the southern side of the Eastern Pyrenees near
