4 PINACEAE. 
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).
