Obs. This noble tree so well known for the references to it, in 

 the sacred volume has been recently introduced, and bids fair to 

 become common, among us. The Deodar Cedar a graceful Ever- 

 green, with drooping branches, less rigid and rather longer bluish- 

 green glaucous leaves has been also introduced ; and apparently 

 belongs to this section. 



f f Leaves soft and deciduous. 



2. L. EUROPXEA, DC. Leaves numerous in the fascicles, flattish, 

 linear, rather obtuse ; strobiles oblong-ovoid, small. 



EUROPEAN LARIX. Larch. White Larch. 



Stem 60 to 80 or more feet high. Leaves an inch in length, proceeding from 

 obtuse, scarious or thin-scaled buds, in beautiful pencil-like tufts, finally often 

 scattered by the elongation of the branches, or internodes. Strobiles about an inch 

 long, purple while young, finally reddish-brown; scopes orbicular, slightly reflexed 

 and jagged on the margin.

 MX.), on our mountains, which is likewise a handsome tree.
