79. P. miiricata (the Bishop's Pine). — This is a very distinct 

 pine, the irregular appearance of its branches and clustered 

 prickly cones beini;; different to those of any other with which I 

 am acquainted. From its leather unustial appearance it is worthy 

 of a corner in the pinetum. It is perfectly hardy, not at all 

 fastidious as to soil or situation, of the easiest culture, and valu- 

 able for planting as game shelter, or for the ornamentation of 

 high-lying and breezy situations. A native of California, and 

 introduced in 1846. 



80. P. parvijlora. — Where a tree of dwarf habit, well-furnished, 

 and compact outline, is in request, this pine may be considered 

 as one of the best. It somewhat resembles the Swiss Stone Pine 

 {P. Cenibra), but with lighter and more enticing foliage, which 

 is of a silvery white. It is quite hardy. A native of Japan, and 

 introduced into this country in 1861. 



81. P. Pinaster (Cluster, or Maritime Pine). — For shelter- 

 giving purposes long experience has proved this to be a most 

 valuable tree, particulai-ly in maritime districts, though an almost 

 worthless species so far as the value of its timber is con- 

 cerned. "When we look at the great value of P. Pinaster for 

 planting as a screen to others of a less hardy nature, and 

 in positions where these could not otherwise survive, this latter 

 quality — timber-producing — can well be dispensed with. For 

 the ornamentation of parks and lawns the Pinaster is a fitting 

 tree ; its tall, massive, and rugged stem, far-spreading, flatly- 

 rounded head, refreshing light-green foliage, and numerous clusters 

 of terra-cotta-coloured cones, all combine to impart an air of 

 massive grandeur that is hardly surpassed by any member of 

 the family. A native of the Mediterranean countries of Europe. 

 Introduced in 1596. 



82. P. pinea (Stone Pine). — Being of slow growth and rather 

 tender condition, few specimens of this pine have attained to 

 large dimensions in Great Britain. As a timber tree in this 

 country it is almost valueless, but its extremely picturesque 

 appearance renders it of great value for ornamental planting. It 

 affords a striking contrast, from its stiff and rounded head, to 

 other trees of an op«n and informal mode of growth. A native 

 of both Europe and Africa. The exact date of introduction is 

 uncertain, but it was prior to 1548. 



83. P. jwvderosa (Heavy-wooded Pine). — As an ornamental 

 tree, there is not much to be said in favour of P. 2>"nderosa, its
