True Pines are evergreen trees, with the adult leaves persistent, 

 in tufts of 2, 3 or 5 ; the flowers are monoecious, males in catkins ; 

 pollen-cells winged ; cones ripening in the second year, woody ; scales 

 (relatively) thin at the tips in § Strobus and § Cembra, thick in 

 § Pinaster. "Wing of the seed ultimately separable, dilated above, 

 prolonged below into two claw-like processes which clip the edges of 

 the seed. Cotyledons variable in number, 3-sided, usually entire, 

 ■whilst the primordial leaves are denticulate. 



The genus Pinus, as here understood, is homogeneous and easily 

 recognisable. Parlatore and some others, however, include under this 

 head all the genera of Abietinese, viz., Pinus, Abies, Picea, Larix, 

 Cedrus, Keteleeria, Pseudotsuga, Pseudolarix, Tsuga — an inconvenient 

 arrangement.
