VITIS 665 



Ampelopsis, Parthenocissus, and Cissus groups are easily rooted from 

 leafy cuttings made in July and August of firm growth. 



I. VITIS (proper). TRUE GRAPE VINES. 



Stems with peeling bark (except rotundifolia). Leaves undivided except in Pagnucci 

 and Piasezkii. Flowers in panicles ; petals united by their ends into a sort of cap, and 

 fallino- before they separate : cestivatis, amurensis, arizomca, armata, bicolor, californica, 

 candicans, Chambini, cinerea, Coignetia, cordifolia, Doaniana,flexuosa, Labrusca, monticola, 

 Munsoniana, Pagnucci, Piasezkii, Romanetii, rotundifolia, rupesiris, Thunbergii, vinifera, 

 vulpina. 



II. PARTHENOCISSUS (or PSEDERA). 



Leaves divided into three to seven leaflets ; tendrils mostly with viscous disks at 

 the tips ; petals separate and expanded. Flowers in compound cymes : Henryana, 

 himalayana, inconstans, quinque folia, semicordata, sinensis, Thomsom, vitacea. 



III. AMPELOPSIS. 



Tendrils coiling, never with viscous tips. Leaves simple to much divided. Petals 

 separate and expanding ; ovary surrounded by a disk : aconitifolia, arborea, brev:- 

 pedunculata, Delavayana, heterophylla, indivisa (cordata\ leeoides, megalophylla, orientalis, 

 serjancefolia. 



V. istriata belongs to the section ClSSUS, and is the only one of that section we can 

 grow out-of-doors. It has much divided leaves, and the disk below the ovary is four- 

 lobed. In other respects much like Ampelopsis. 



A Himalayan vine, V. CAPREOLATA, D. Don, has been many times introduced, but is 

 not hardy. It is distinguished by having the inflorescence produced from the axil of the 

 leaf instead of opposite to it. It belongs to Planchon's genus TETRASTIGMA as 

 T. SERRULATUM. Leaves digitate, composed of five leaflets, one or both lower pairs 

 united on one stalk. V. OBTECTA, recently introduced from China, is of the same group. 



V. ACONITIFOLIA, Hance. 



(Ampelopsis aconitifolia, Bunged) 



A slender-stemmed, luxuriantly leafy, deciduous climber; young shoots 

 smooth. Leaves very variable in shape and size, composed either of three 

 or five stalkless leaflets radiating from the end of a common stalk which is 

 \ to 2 ins. long. The leaflets are lanceolate or diamond-shaped in general 

 outline, but always deeply and coarsely toothed, and often conspicuously 

 three- or five-lobed, the lobes reaching sometimes to the midrib. The 

 entire leaf is 2 to 5 ins. across, the leaflets i to 3 ins. long, deep glossy 

 green above, pale beneath, and smooth on both sides except for small tufts 

 of down in the vein-axils beneath. Flowers produced in August and 

 September in numerous forked cymes. Fruits scarcely J- in. long, roundish 

 obovate, purple. 



Native of China. Of the vines with compound leaves and deeply cut 

 leaflets this is the hardiest and most luxuriant in growth. It can be trained 

 up a tall post, which it will soon cover with a beautiful tangle. There has 

 been some confusion in gardens between this species and another vine, also 

 of the Ampelopsis group, viz. : 



V. SERJANCEFOLIA, Maximowicz (Ampelopsis serianaefolia, Bunge). This 

 is a native of Japan, Corea, and China, and quite distinct in foliage from 

 V. aconitifolia. The leaflets are in threes or fives, and in the latter case 

 are arranged pinnately on the common stalk (not all radiating from its end 

 as in the other). Another distinction is that the leaf-stalk between the pairs of 

 leaflets is winged. Sometimes the lowest pair of leaflets are themselves 

 pinnately divided. In other respects the leaflets are dark green above, pale
