CELASTRALES. 537 



a, the Ohio Buckeye, and several other species, are 

 native ornamental trees of the sub-order. 



jE. Hippocastanuin, the Horse-Chestnut of the Old World, is com- 

 monly planted. 



Kcelreuteria paniculala, a Chinese tree, and Card iosper mum Jlalica- 

 cabum, the Balloon Vine of the Southern United States, are cultivated 

 as ornaments. 



Nephelium Lilchi, a small Chinese tree, produces the pulpy edible 

 fruits imported under the name of Litchi. N. Longan produces the 

 similar fruit called Longau. 



Melicocca bijuga, a tree of Guiana, yields a hard and heavy timber, 

 and from Cupania pendula, of Australia, is obtained Tulip Wood, 

 which, in some respects, resembles Mahogany. 



The stem of the climbing plant, Paullinia curassavica, of Venezuela, 

 is made into the walking-sticks called " Supple 



Jacks." 



596. Cohort XXVIII. Celastrales. 

 Flowers actinomorphic and monoclinous; 

 ovary superior entire ; seeds usually with 

 endosperm. 



Order Ampelideae. Mostly climbing 

 shrubs, with nodose stems, bearing petioled al- 

 ternate leaves ; tendrils and flower clusters op- 

 posite to the leaves. About 250 species are the normal circle of 

 known; they abound iu the tropics and are gf LteSS^lfi ? b 

 much rarer in temperate climates. two are fully developed, 



-rr,. . .. . . , ... . i n shaded lighter, the abor- 



Vltis is the principal genus; it contains all tive ones represented by 



the true Vines (grape producing), and many dots. After Sachs, 

 others whose fruits are inedible. (Figs. 494-501.) 



Vitis mnifera, the Vine of the Old World, has been under cultiva- 

 tion from time immemorial. It is indigenous to Southern Asia, from 

 whence it has been carried to nearly all parts of the world. Its varie- 

 ties are almost innumerable. From those grown in Southern Europe 

 wines and raisins are made, the latter being merely the sun-dried 

 grapes. 



In the United States the Old World Vine is grown in the Southern 

 and Pacific Coast States, and in the latter region fine raisins are made. 

 In other portions of this country only the native species are grown, viz. : 



V. Ldbrusca, the Northern Fox Grape ; from this have originated 

 most of the common varieties, as Catawba, Concord, Isabella, etc. 



V. astivalis, the Summer Grape, from which we have obtained thte 

 Virginia Seedling, Herbemont, etc. 



V. riparia, the River-bank Grape, which has produced the Taylor 

 Bullit, Delaware, and Clinton.
