24 VITIS INDIVISA. ENTIRE-LEAVED IVY-GRAPE. 



and Prof. Wood says " swamps, Southern States to St. Louis," 

 while Torrey and Gray, in the " Flora of North America, ' 

 locate the plant in the " Southern States west to Louisiana and 

 Arkansas." We may add that in Ohio it is probably confined 

 to the southern part of the State. A writer in the " Botanical 

 Gazette " reports having found it in Eastern Indiana, and the 

 writer of this has himself collected it in Kentucky, Tennessee, 

 and Northern Texas, hi fact the plant from which our drawing 

 was made was raised from cuttings brought from the state last 

 named. 



In its native places the Vitis indivisa is a strong-growing 

 vine, completely covering the low trees over which it climbs, 

 and forming picturesque, hollow masses of foliage, resembling 

 arbors. In the fall of the year the leaves turn to a yellowish or 

 orange brown, which with the red, blue, and black berries form 

 a very attractive combination of colors. In the hands of the 

 skilful landscape gardener our plant ought to be a most valua- 

 ble element. Like most of the species of the grape family, it 

 can be raised easily from cuttings as well as from seeds. 



To the close observer the grape-vines offer many points of 

 interest. The nodes, or joints in the stem, usually produce ten- 

 drils at certain regularly recurring intervals, or rather each node 

 without tendrils is preceded and followed by a fixed number of 

 nodes with tendrils. Mr. Darwin has shown that these tendrils 

 are in continuous motion, sometimes for several days, until they 

 have found something to cling to, and the writer of this has 

 demonstrated that this motion, if it remains unsatisfied, has a 

 most exhaustive effect on the health and vigor of the plant. 

 There are, indeed, very few plants that will afford so great a 

 variety of interesting themes for study as the various species of 

 the grape.
