Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches. Gardening. 2675. The coilinE of tendrils; a shows the tendril hooks ready to grasp a support; b, shows the coiline of the tendril-branches and the straight or not-coiled spaces where the direction of the coil is reversed. Cassa- banana (Sicana;. 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 these phenomena may be seen in Fig. 2675, w^hich represents the tendrils of one of the Cucur- bitacese. All members of this family, as cucumbers, melons, pumpkins and wild balsam apple, are excellent subjects on which to observe these phenomena. 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 quinquefolia, 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 trlcuspidata {A. Veitclii). Fig. 2670; also Fig. 81, Vol. I. A neater and handsomer vine than the Virginia creeper, clinging closer, but it is often in- jured by winter in exposed plac
