 Autumn wood without them : no groups, practically all single : 

 round. 



Rays. Need lens, very fine, size 6, uniform : straight, long : 

 very slightly denser than the ground- tissue, difficult to see with 

 lens in a transparent section : rather numerous, 5-11 per mm. : 

 white : much more than a pore-width apart. 



Rings. Clear. Boundary a narrow, pore-less zone of Autumn 

 wood, little contrast except by depth of colour : always narrow, 

 i.e. of slow growth.

Radial Section. A trifle lighter in shade than the Transverse. 

 Pores need lens, practically imperceptible. Rays just visible 

 with lens in certain lights. Rings indicated by variation in light 

 and shade with a faint, fine line at the boundary. 



Tangential Section. As the Radial, but the rays are imper- 

 ceptible except with the microscope in any light. 



Type specimens from commercial sources as regards the 

 foreign woods, but from trees known before felling in the case 

 of the English Boxwood.
