Trees for Shade and Ornament 



Other willows having some desirable points are S. incana, Schrenck. 

 (325), 5. rosmarinifolia Willd. {incana), (326), a shrub of ver\' fine foli- 

 age, and 5. argyrocarpa Anders. (327), a native shrub of beautiful satiny 

 luster. 



Entirely distinct from all the rest by reason of its larger, broad, dark 

 green, extremely glossy, almost leathery foliage, and its round, com- 

 pact, dense head, is 5. pentandra Linn. (328) {laurifolia), Laurel Leaf 

 Willow from Europe and Asia, adapted for narrow streets as well as 

 small places, on points which make an accentuation desirable, and for 

 quickly screening out objectionable surroundings, also for hedge work 

 and for seashore planting. 



SASSAFRAS 



Sassafras. 5. officinale Nees. (Sassafras) (329), a small, native tree, 

 of wide distribution; with roundish outline; among the best ornaments 

 for small places, pleasing and picturesque in its variegated color effects 

 of foliage, fruit, and bark, and its conical to roundish or fiat outline, 

 with shelving, horizontally spreading branch habit. The peculiar 

 yellowish-reddish tint of the oddly lobed foliage, turning reddish brown 

 to orange in autumn, is heightened by the reddish basis of the leaf- 

 stalks, the bright reddish, small fruit, and the greenish to yellow bark 

 of branchlets and gray-brown color of stems and branches; the latter 

 peculiarly furrowed, giving it "an appearance of age and adding 

 antiquity to a new place." Its yellowish flower clusters in early spring, 

 about leafing time, and its long leaf period are additional claims for 

 more extended use. On dry, light, sandy loam, in warm and sunny 

 positions, it develops best. Although with a long tap-root, it is easily 

 transplanted when young. Being dioecious, i.e., male and female 

 trees separate, care should be taken to secure the female trees. Gen- 

 erally free from insects and fungi but liable to sucker. Used in single- 

 ness, or as a filler in woodland planting and large borders. 



TAMARISKS 



Tamarix. Of the sixty species found around the Mediterranean, in 

 India and Japan, there are three species worthy of more attention than 

 they have received. They are most exquisite, delicate, shrub-like trees 

 of airy appearance, with minute, pale green foliage, slender, lithe,
