LARGE SHRUBS 255 



Jt Shoots and leaves abounding in white 

 latex. Twigs greyish to brown. Leaves 

 variable, some lobed. Flowers small 

 and crowded, unisexual. Fruits com- 

 pound, fleshy. 



Morus alba, L. Mulberry (Fig. 128). Shrub, or stunted 

 tree, up to 30 feet, and apt to form suckers. The stiffly 

 branched crown is often due to pollarding. Twigs more 

 or less hairy at tips, otherwise smooth, shining and 

 rounded. Older branches grey-brown and finely fissured. 



M. nigra, the Black Mulberry, has stouter and smoother 

 twigs and branches, polished olive to yellowish grey-brown, 

 and generally darker hued to blackish-grey. Twigs more 

 angular, and may be a tree up to 30 40 feet or so. 



Rhus typhina, a loosely branched shrub, or bushy tree, 

 up to 20 feet or so, with olive-brown densely hairy shoots, 

 becoming smooth and shining with prominent lenticels, 

 may also be placed here. The leaves are pinnate, and 

 richly coloured red, purple, &c., in autumn ; the twigs 

 stout and blunt, and suckers abound. The older shrubs 

 are usually recognisable by the long persistent cylindroid 

 heads of densely crowded and hairy, purple infructescences.
