THE PINE SUB-FAMILY. 147 



68. P. Monteznm<e, Lambert. Forms a medium- 

 sized or rather large tree, from 40 to 60 feet in height, on 

 the mountains of Mexico, and is probably as hardy as any 

 of the Mexican species. Timber, quite excellent. 



69. P. OCCidentalis, Swartz. A species from the 

 West Indies, where it attains the height of 20 or 30 feet, 

 and very much resembles the P. Halepensis. It is quite 

 tender in England. 



70. P. OOCarpa, Schiede. A Mexican species grow- 

 ing from 40 to 50 feet high, with rather long, slender, pen- 

 dulous leaves of a light green color. The var. oocarpo- 

 ides, of Bentham, is a more beautiful plant with slenderer 

 leaves and smaller cones, and perhaps attaining a larger 

 size. 



71. P. Orizafoaej G-ordon. Is another of Hartweg's 

 discoveries from the Orizaba Mountains, in Mexico, grow- 

 ing only about 30 feet high, but forming quite a handsome 

 tree. 



72. P, Pence, Gfrisebach. (?) This handsome pine, 

 which has been incorrectly placed as a synonym of P. 

 Cembra, by Gordon, is a native of Macedonia, on the sides 

 of Mount Peristeri, and is more nearly related to P. Stro- 

 bus than to P. Cembra. It is the " PeuJce " of the Greeks, 

 and may perhaps live in our climate. 



Since the above was written, we have been enabled to 

 obtain additional and more reliable information in regard 

 to this new pine (?). In the year 1839, Dr. Grisebach was 

 travelling in Rumelia and observed a 5-leaved pine which 

 he thought new. The locality was on Mount Peristeri, an 

 eastern district of Macedonia bordering on Dalmatia, in 

 lat. 41 N"., Ion. 21 K, and it grew in an uninterrupted 

 wood of trees from 2,400 to 5,800 feet in altitude. In favor- 

 able situations it formed -a tree about 40 feet high, but
