704 KOSA. [class xii. order hi. 



Habitat. — Heaths and waste places, especially in a sandy or chalky 

 district. — j3. pilosa, Ireland, Lindley. 

 Shrub; flowering in May and June. 



It is trom this species that the great variety of the Burnet or Scotch 

 Roses of our gardens is obtained. It varies very greatly in the size 

 of the shrub, the fragrance of the flowers, and the shape ot the 

 leaves ; this, however, does not alter the appearance for which it is 

 distinguished, as resembling the leaves of the Burnet. It may have 

 been the delicacy of this pretty simple Rose, with its very spiny 

 branches, which suggested to the mind of Ariosto the following lines : — 



La virginella e simile alia rosa, 



Ch' in bel giardin, sulla nativa spina, 



Mentre sola e sicura si riposa, 



Ne gregge ne pastor se le avvicina; 



L' aura soave e 1' alba rugiadosa, 



L' acqua, e la terra al suo favor s'inclina : 



Giovani vaghi, e donne innamorate, 



Amano averne e seni e tempie ornate. 

 Ma non si tosto dal tnaterno stelo 



Rimossa viene, e dal suo ceppo verde, 



Cbe quanto avea dagli uomini e dal cielo 



Favor, grazia e belezza, tutto perde. 



La vergine che il candor, di che piiX zelo, 



Che de' begli occhi e della vita aver de', 



Pregiar non mostra; il pregio ch' avea innante 



Perde nel core d' ogni saggio amante.
