of the grape, are mortified branches or stems; others, 

 as those of the pea anrt cobsea, are modifiert leaflets; still 

 others, as in some species of lathynis, are modified stip- 

 ules. True tendrils are always definitely arranged with 

 reference to the position of the leaves. The young ex- 

 tended tendril usually swings about in a circle or ellipse, 

 its end being somewhat bent or coiled. When this end

 where the direction of the coil is reversed. Cassa- 



strikes a support it fastens itself securely, and then the 

 plant is drawn to the .support or held to it by the coiling 

 of the tendril. This coil also serves as a spring whereby 

 the plant is held to its support during winds. The con- 

 tinuous coiling of the tendril in one direction would 

 twist the tendril in two; therefore, tendrils usually coil 

 in more than one direction, one part of the length being 

 coiled from right to left and another part from left to 

 right. Some of tli.-.f ]ili. iHiini'iia may be seen in Fig.

Of the very many vines that may be used with good 

 results in the open air in the North the following are 

 common and therefore to be commended. Many green- 

 house vines can also be used in the open during the 

 summer, but these are not included in the present list. 

 AA. Top shrubby. 



Ampelopsis quinquefoUa, Virginia creeper. Figs. 80, 

 1866. The best single vine for covering buildings and 

 arbors, since it is perfectly hardy and thrives under 

 many conditions. Plants should be selected from vines 

 of known habit, as some individuals cling much better 

 than others. 



Ampelopsis tricuspidata {A. Veitchi). Fig. 2676; 

 also Fig. 81, Vol. I. A neater and hand.somer vine than 

 the Virginia creeper, clinging closer, but it is often in- 

 jured by winter in exposed places, especially when 

 young. It is best adapted to stone and brick buildings. 



Clematis of various species. G. paniculata and C. 

 Virginiana are best for general use. 



Tecoma radicans, trumpet creeper. 



Vifis or grapes of various species. The wild species 

 are preferable. Fig. 2677. 



Hedera Belix, true ivy. Fig. 1023. The English ivy 

 does not endure the bright sun of northern winters. 



VINES 



Hardy in middle states, and often does well on the north 

 side of buildings farther north. 



Acliindia arguta. Fig. 29. One of the best arbor 

 vines. 



Akebia quinala. Figs. 56, 57. Graceful and pretty. 



Lonicera sempervirens, h. flava and other honey- 

 suckles. L. Japonica (or L. Balliana) is half evergreen 

 in the North and is popular. 



Arixlolochia mairoijhylhi, Dutchman's pipe. Figs. 

 1.38-140. A robust grower, with enormous leaves. Use- 

 ful for covering verandas and arbors. 



Celastnis scandens, waxwork or false bittersweet. 



Wistaria Sinensis and W. speciosa. Figs. 2475, 

 2476.

Vines for the South. I. Deciduous. Ampelopsis tri- 

 cuxpidata and quiniiiiefolia are exceedingly popular for 

 covering brick walls, stumps, or dead trees. Being de- 

 ciduous, they are free from the objection of evergreen 

 ivies, whose foliage often accumulates dust and is a harbor 

 for sparrows' nests. A. arborea retains its black ber- 

 ries all winter; the form with variegated foliage is most 

 desirable. — Bfj-c/iemid scandens has small, greenish 

 flowers; not showy, but of rapid growth in moist soil. 

 — Oelastrus seandens is desirable for its orange-colored

capsules and scarlet seeds, which are retained during a 

 part of the winter.— 'C'cMfros«»ia I'irginianum, a twin- 

 ing herb, is a very desirable small vine. The large, 

 pea-shaped lavender flowers are produced from May 

 until auUimn. — Clematis. The best native species are 

 C. crispa, with dark bluish purple carapanulate flowers, 

 C. corcinea with scarlet campanulate flowers, and C 

 holnsericca. conspicuous for the silky plumose tails of 

 the akenes. All those are herbaceous and lose their 

 stems during winter. Of the hybrid garden varieties
