PlNACEAE. 



Larix. Larch. Tamarack. 

 (Family Pinaceae). 



Percurrent scaly-barked trees 

 with often drooping branchlets: 

 deciduous. Twigs slender: pith 

 minute, brown, roundish, inter- 

 rupted at the junctures. Buds 

 solitary, sessile, small, globose or 

 short-ovoid, with numerous brown 

 sometimes slender pointed scales. 

 Leaf-scars alternate, raised on de- 

 current sterigmata, half-round or 

 3-sided, minute, mostly clustered 

 on spurs that lengthen very 

 slowly: bundle-trace 1: stipule- 

 scars lacking. Fruit persistent, as 

 ellipsoid cones with thin persistent 

 scales, in this respect resembling 

 the spruces and hemlock. 



1. Twigs pubescent: bark becom- 

 ing red. L. occidentalis. 

 Twigs glabrous. 2. 

 2. Bark dark gray: twigs straw-colored: cones puberulent, 

 large (2-4 cm. long). (European). (1). L. decidua. 

 Bark red-brown: twigs rather orange: cones glabrous and 

 often glaucous, small (under 2 cm. long). (2). L. laricina. 



Pseudolarix. Golden Larch. 

 The golden larch (Pseudolarix Kaempferi, sometimes 

 called Laricopsis Kaempferi), sometimes seen in cultivation, 

 differs from the true larches in that the scales of its cones 

 fall off at maturity, as, for example, in the firs (Abies).
