shelter for the famous Tresco gardens. A few trees have been 

 used with Austrian and Corsican pines to cover the sand-dunes 

 at Holkham, the Earl of Leicester's estate in Norfolk. They 

 have grown fairly well, but the position is evidently more suit- 

 able for the hardier trees. The botanical varieties referred to 

 above are rarely seen in cultivation, although amongst a large 

 number of trees it is probable that individuals could be selected 

 answering to the descriptions. P. Pinaster has given satisfac- 

 tory results in S. Africa.

Native of Mexico from S. Coahuili to C. Hildago, where it 

 grows along watercourses and is often associated with P. cem- 

 broides. 



It is not known to be in cultivation, and possesses no import- 

 ant economic properties.
