GENERA OF FINALES 



(e) The Principal Genera of Finales. — The more important 

 genera of Finales may be distinguished as follows: Piniis or 

 pine, leaves long and needle-like, borne in fascicles on short stems 

 that are quite concealed by papery sheathing scales (Fig. 251, i). 

 Larix or larch, short needle-like leaves clustered in tufts on short 

 lateral branches. This is the only northern member of the order 

 with deciduous leaves. Picea or spruce, leaves angled or four- 

 sided, radiating from all sides of stem, petioles remaining on 

 branchlet after leaves fall, thus causing the rough appearance of 

 the branchlets (Fig. 260, 9). Tsuga or hemlock, leaves flat in 



7 



Fig. 260. Common examples of the Finales: 5, Thtija or arbor vitae. 

 6, Strobiliis of Chamaecyparis or southern white cedar. 7, strobilus of Jtini- 

 ferus or red cedar with fleshy scales fused into a berry-like fruit. 8, branch 

 of Taxus or yew. The seeds are produced singly in the axils of leaves on short 

 lateral branches and nearly enveloped by a thick fleshy cup that becomes 

 bright red. 9, Picea or spruce.
