DecuiwpjLH trees. 



Acer saccharinum (A. dasycarpum) and A. Negundo, 

 the latter extxinsively used for street planting. — Brous- 

 aortetin papifrifero, fonnerly planted along streets, but 

 objectionable because of the many suckers which they 

 prfxluf*, as is also li. Kazinoki. — Cercis canadensis. 

 Valuable as an early spring-flowering tree. — Celtis 

 Hungean/i. One of the most distinct trees; an excellent 

 Hha<lc tree. — Calalpa. Seldom i)lant(-d South as an 

 'jmamental tree, becau.sc of the repeated attacks of 

 caterjiillarB. The latter are frequently used for fish 



bait. — Cladraslis tinctorin. Very desirable as a flower- 

 ing lawn tree. — Cornus flurlda. The wliilc-iluwcring 

 species is among the most attractive of our early spring- 

 bloonui\g trees and is largely u.scd in landscape work. 

 The pink- and red-llowering forms are exceedingly 

 beautiful. — Vriilirgiis. Taking into account the various 

 shapes, Hie foliage and the bright-colored fruit in fall 

 and wintei', the best are: ('. Ph;riiiipyriii)t or Washington 

 thorn, ('. (irbonxciiis, C. spaDiidaiii :ind C. ifslivalis 

 or apple haw. — t'hitopsix s<diii)i<i, known as C. lineans, 

 is one of the best for dry soils. The typical species pro- 

 duces lilac-colored llowers, but several forms have lately 

 been produced with llowers ranging from light lilac to 

 lilac-purple with yellow stripes inside. A pure white- 

 flowering form is very striking but is of more dwarf 

 habit. — Uiospyros virginiuiia. Sometimes planted for 

 shade or for its fruit. Adajits itself to nearly all soils 

 There are many forms varying both in the foliage and 

 size and shape of fruit. — Furjus yrandifulia is frequently 

 used for street planting in sandy soils. The red-leaved 

 forms of the iMiropean species are of little value South, 

 the purple tint of the foliage fading to a dull green at 

 the a]>pi'oach of warm weather. — Fraxinus acuminata 

 and F. puhesccns. Both thrive best in rich soils and are 

 very desirable for street planting, being seldom attacked 

 by insects. — Ginkgo or Salisburia is sometimes used 

 for avenues and street planting where a rigid pyramidal 

 tree is required. The foliage is one of its attractions, 

 being shaped like the maidenhair fern. — Gledilsia 

 IriacaiUhos. The fertile tree is sometimes planted for 

 its large falcate poils, which are relished by many for 

 the saccharine acidulated pulp. The finely pinnate foli- 

 age is very ornamental. — Ilalesia telraptera. In the 

 middle sections of the South and in rich, dry soils it 

 grows to a small tree, but in the mountain districts in 

 rich soils along the water-courses, trees 40 to 50 feet 

 liigh are frequently found. Valuable for landscape 

 planting. — Carya or Hicoria. The pecan is the best 

 southern nut tree and is very largely planted for its 

 nuts. It is often planted in avenues for its beauty. — 

 C'lirya myristicseformis is scarce, but its foliage is more 

 attractive than that of any other species. — Hovenla 

 dulcis. The foliage and the fleshy red peduncles in 

 autumn make it an excellent shade and ornamental 

 tr(!e. — Idf.sia polyairpa. A handsome tree when grown 

 in partial shade; the bark blisters in full sun. — Jug- 

 Ui/is. .J. nigra is one of the most valuable ornamental 

 and economic trees and is extensively planted for 

 avenues. The Persian or Knglish walimt and its many 

 forms aie being more largely planted than of old, but 

 are often injured by late spring frosts following a warm 

 period during February. J. Sirboldiana is a very orna- 

 mental tree and very productive at an early age. J. 

 cinerva is suited only to the mountain regions of the 

 South. — Kailreutcrid paiiicuUitd. Very desirable for its 

 pinnate foliage and panicles of yellow flowers, which 

 are succeeded by bladder-like fruits. — Lagerstramia 

 iiidica. The crape myrtle is one of the most character- 

 istic features of southern homes. It has become almost 

 naturalized South. If trained to a single stem, it will 

 form a tree 2.") to 30 feet high; otherwi.se it affects the 

 bush form. It is conspicuous for its shining brown bark 

 and the profusion of its beautifully crimped and fringed 

 flowers, which are produced from April until August. 

 The colors vary from a jjale to a dark pink, purplish 

 red, pure white and glowing crimson. No other flower- 

 ing tree can surpass it in beauty, and by a judicious 

 sele<:tion of the various colored flowers a grand effect 

 is produced in landscape work. — Liriodindron Tulipif- 

 era. One of the most valuable and rai)i(l-prowing shade 

 and ornamental trees; thrives best in rich soil. Trees 

 taken from woods transplant badly. They should be 

 grown in nursery and occasionally tiansplanted until 

 sudiciently large for using in sireet planting. — Liquid- 

 ambar. A most symmetrical shaped tree; adapts itself 

 to all soil; valuable for street planting. Some trees
