while the cones of C, atlantica are considerably smaller, 

 about 5 6 x 4 cm. _ 



ZZ7/Z7 Cones 3 5 cm. long, with fewer and 

 much looser scales, just showing the tips 

 of the barren scales; seeds ivith obliquely 

 sub -acute narrow wings; leaves in tufts 

 of 25 60 and deciduous. 



Larix europcea, L. Larch (Fig. 80). 



(b) Cones small, the scales not spiral, but 'opposite and 

 decussate ; seeds not truly winged, but with a 

 narrow membranous border; leaves scaly, opposite. 



(i) Cones globoid, of 8 10 scales, which are 

 peltate at the ends, each bearing several 

 seeds, the latter small, 6x4 mm., irregular 

 and hardly winged. 



Cupressus sempervirens, L. Roman Cypress (Fig. 81). 



(ii) Cones elongated, of 8 12 imbricated narrow 

 scales, which are not peltate ; scale with

2. [Juniperus has fleshy cones forming the so-called 

 "berries"; see p. 135.] 



B. SEEDS NOT SHED FROM BETWEEN THE SCALES OF 



A WOODY CONE. 



[The cone-like infructescences of Alnus bear scales of 

 complex structure, on which are borne seed-like fruits ; 

 neither these nor the catkins of Betula, Myrica, &c. are 

 morphologically equivalent to true cones ; see pp. 97, 95, 

 122. The fleshy cone of Juniperus is dealt with on p. 135.]
