TREES OF THE NORTHERN UNITED STATES 





GENUS 107a. TORBJ&YA. 



The Torreyas are much like 

 the Yews, but their leaves have 

 two longitudinal lines, and a re- 

 markably disagreeable odor when 

 burned or bruised. Torr^ya 

 taxifolia, Arn.,from Florida, and 

 Torrdya Californica, Torr., from 

 California, have been often plant- 

 ed. They form small trees, but 

 probably cannot be grown suc- 

 cessfully in the region. The fig- 

 ure shows a twig of T. taxifolia. 



T. taxifolia. 



GENUS 107b. CEPHALOTAXUS. 



Cephalot&xus Forturni, Hook., 

 does not form a tree in this section, 

 but a wide-spreading bush growing 

 sometimes to the height of 10 ft., and 

 spreading over a spot 15 ft. wide. 

 Leaves flat, with the midrib forming 

 a distinct ridge on both sides, linear, 

 sometimes over 2 in. long, glossy green 

 on the upper side, slightly whitened 

 beneath. Fruit very large, 1 in. or 

 more long, elliptical, with a single, 

 thin-shelled nut-like seed covered with 

 purplish, pulpy, thin flesh. Branches 

 spreading, drooping, long, slender ; 

 buds small, covered with many sharp- 

 pointed, overlapping scales ; twigs 

 green, somewhat grooved. From 

 Japan ; about hardy in New Jersey. 



GENUS 108. PODOCARPUS. 



Leaves one-nerved, opposite, alternate, or scattered, 

 linear or oblong. Flowers axillary and mostly dioecious; 

 fruit drupe-like, with a bony-coated stone.
