MEXICAN PINES. 



Among* the collections of seeds formed in 1838 in tlie 

 mountainous districts north of Mexico, by Mr. Hartweg, for 

 the Horticultural Society, are many species of Pinus, among 

 which six are quite new. As the Society is about to distri- 

 bute the seeds of these plants, it is desirable that they should 

 in the first instance be described, in order that no confusion 

 may be hereafter introduced among the garden plants. They 

 may therefore bear the following names. 



95. PINUS Hartiver/ii; tetraphylla, foliis secundariis angustlssimis primariis 

 inembranaceis elongatls scariosis, strobilis pendulis oblongls obtusis aggre- 

 gatis ; squamis apice transversis medio depressis umbonatis ccarinatis um- 

 bone recto rotundato, seminibus subrotundis cuneatis ala testacea 4-pl6 

 breviorlbus. 



The cones are about four inches long, and about two 

 inches or rather more in diameter, of a clear greyish brown, 

 and as broad at the one end as the other. The branches are 

 very stout, like those of P. palustris. The leaves are almost 

 invariably in fours, and rather more than six inches long. 

 Mr. Hartweg sent it from the " Campanario," where he found 

 it forming a tree 40 or 50 feet high, and beginning to appear 

 where the Oyamel, or Abies religiosa, ceases. 



96. PINUS Devoniana ; pentaphylla, foliis longissimis, ramis crassissimis, 

 strobilis pendulis solitaiiis corniformibus obtusis : squamis apice rotundatis 

 rbomboideis linea transversa paulo elevata opacis griseis medio abrupte um- 

 bonatis obtusis Isevigatis, seminibus obovatis ala nigricante quintuple 

 brevioribus. 



This noble species is the " Pino bianco," or " P. real," of 

 the Mexicans. Mr. Hartweg describes it as a hardy tree 

 I'rom 60 to 80 feet high, found on the Ocotillo between Real 

 del Monte and Regla. The cones are from nine to ten 

 inches long, curved, about three inches in diameter near the 

 base, and tapering till they are not more than one inch and 

 three-quarters broad at the point. The young shoots are 

 nearly an inch in diameter, and look very like those of Pinus 

 palustris. It is worthy of bearing the name of His Grace 

 the Duke of Devonshire, whose arboretum at Chatsworth 

 will it is to be hoped be soon augmented by this truly regal 

 plant.
