LXXVII. CONIFER^E:

longer than others The 

 scales are about 2 in. 

 long, standing open, 

 with their points more 

 or less bent down- 

 wards ; the rhomboidal 

 surface is much longer 

 than it is broad, inter- 

 sected by many wrinkles 

 lengthwise, of a dull 

 greenish and yellowish 

 brown colour. Seed 

 winged, 1 in. long, and 

 from 8 to 12 lines broad 

 at the top, where it is 

 broadest. It is small 

 in proportion to the 

 cone. The wing has 

 almost the appearance 

 of the upper wings of 

 many small moths, being 

 brownish, with dark 

 stripes running length- 

 wise. (Sc/ilecht.) A 

 large tree. Mexico, at 

 Omitlan, near Hacienda 

 de Guerrero, and other 

 places. Height 100 ft. 

 Introd. to H. S. Gard. 

 in 1840 by Hartweg. 

 A great deal of resin 

 exudes from the whole 

 cone, as in Pinus tftrobus, 

 to which this species is 

 nearly allied; but it differs 

 in the points of the scales, 

 which in this species are 

 bent downwards, whereas 

 in P. Strobus they are 

 bluntly rounded, obtuse, 

 and stand upright.

GENUS II. 



D. Don. THE SPRUCE FIR. Lin. Syst. Monce'cia Monadelphia. 



Identification. D. Don in Lamb. Pin., vol. iii. 



Synonymfs. Pinus of Lin. and others, in part ; Ptcea Link in Abhand. Konig. Akad. Wissens. 

 Berlin, p. 179. for 1827, (the ancients called the silver fir ,4'bies, and the spruce fir Pfcea; but, by 

 some inadvertence, Linnaeus reversed these names : Professor Link has restored them in the 

 essay quoted, but we have not thought it advisable to depart from the customary nomenclature, 

 by following him) ; .4'bies of Tourn., Mill., and others, in part ; Picea of the ancients ; Sapin 

 epicea, Fr. ; Fichtenbaum, Ger. ; Abete, Ital. ; Abieto, Span. 



Derivation. From abeo, to rise ; alluding to the aspiring habit of growth of the tree : or, according 

 to some, from apfos, a pear tree ; in allusion to the form of the fruit. 



Gen. Char. The same as Pinus : but with the cones pendent, and less de- 

 cidedly grouped ; the strobiles cylindrical ly conical ; the carpels not thick- 

 ened at the tip ; and the leaves solitary, partially scattered in insertion, and 

 more or less 2-ranked in direction. Carpels and bracteas adhering to the 

 axis of the strobiles. (D. Don.}
