12 41. RUBIACE^. 



(Miss Emma Trevelyan, in Hook. Brit, Flo.); on the 

 genuine nativity of which a doubt has been thrown, because 

 the trees are said to have been brought from Nonvay : was 

 this the fact ?

Estimate of provinces 6. Estimate of counties 20. 



Latitude 50 — 54. Atlantic type of distribution.

Descends to the coast level, in the Peninsula. 



Ascends to 50 or 100 yards, in the same province.

Native. Rupestral and Sylvestral. In addition to the 

 half dozen counties above mentioned, the Rubia is recorded 

 to gi'ow in those of Devon, Somerset, Dorset, Wilts, Sus- 

 sex, Gloucester, Monmouth, Glamorgan, Pembroke, Car- 

 digan, and likewise Cambridge ; but in respect to the latter 

 county there would appear to have been some mistake, 

 since the plant is not found by the Cambridgeshire bota- 

 nists of the present day. For the province of the Lakes, 

 there is no better authority than the statement of a former 

 local guide, utterly untrustworthy. And the West-High- 

 land province, originally indicated for this species by Dr. 

 Mitchell (Linn. Corresp. — Eng. Flo.), was undoubtedly an 

 error. It is not very likely that the Rubia will be found in 

 20 counties ; but being known already in 16, the next step 

 in the descending estimate (15) would probably be as much 

 too low as 20 may be above the actual number.
