MEXICAN PINES. 
Among the collections of seeds formed in 1838 in the 
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 Hartwegii, ; tetraphylla, foliis secundariis angustissimis primariis 
membranaceis elongatis scariosis, strobilis pendulis oblongis obtusis aggre- 
gatis; squamis apice transversis medio depressis umbonatis ecarinatis um- 
bone recto rotundato, seminibus subrotundis cuneatis ala testaceà 4-pló 
brevioribus. 
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 ) oce solitariis corniformibus obtusis: squamis apice rotundatis 
rhomboideis lineá transversá paulo elevatá opacis griseis medio abrupté um- 
bonatis obtusis levigatis, seminibus obovatis ala nigricante quintupló 
brevioribus, 
This noble species is the ** Pino blanco," or ** P. real," of 
the Mexicans. Mr. Hartweg describes it as a hardy tree 
from 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 
se it is to be hoped be soon augmented by this truly regal 
plant.
