The wood of (he trees of this order lias no very marked general 

 distinguishing characteristic \ bul siill ii may he said that it is noticeable 

 for the pores being usually more scanty than in many other orders. In 

 some genera they are characteristically arranged in short radial lines. 

 In almosl all genera the pith-rays are fine, close and uniform; in some 

 they are very indistinct. In other genera transverse ladder-like hars 

 are conspicuous. In respect to color, there are three classes, I he white 

 or gray, (he red, and the brown or grayish-brown. In respect to weight, 

 some are very light, most moderately so, few or none very heavy. Among 

 white-wooded genera (lie most noticeable are:
