crevices the tips of the tendrils form large balls of tissue, the outer 
parts of which become mucilaginous and cement the tendril to its 
support. V. vinifera L. (Orient, N.W. India) is the cultivated grape; 
when dried the fruits form raisins. The currants of commerce are 
the fruit of the Corinthian variety (currant is a corruption of Corinth). 
V. aestivalis Michx. (summer-grape) and V. Labrusca L. (fox-grape) 
are N. Am. sp. which have been largely introduced into Eur., as they 
resist the attacks of the dreaded insect, Phylloxera, better than the 
Eur. sp. V. ( A .) hederacea Ehrh. (N. Am.) and V. inconstans Miq. 
(A. Veitchii hort. ; Japan) are the Virginian creepers so often culti- 
vated. 
Vittadinia A. Rich. Compositae (ill). 8 sp. New Guinea, Austr., 
New Caled., N. Z., S. Am. 
Vittaria Sm. Polypodiaceae. 10 sp. trop. and subtrop. 
Voandzeia Thou. Leguminosae (in. 10). V. subterranea Thou, is the 
only sp. (trop. Afr.); it buries its young fruits like Arachis. The 
seed is edible and the plant is largely cultivated. 
Vochisia Juss. ( Vochysia Poir.). Vochysiaceae. 54 sp. trop. Am. 
Vochysiaceae. Dicotyledons (Archichl. Geraniales). 5 gen. with 80 
sp. trop. Am. Trees and shrubs, rarely herbs, with opp. or whorled 
simple leaves, with or without stipules. Firs. $ , typically 5-merous, 
obliquely zygomorphic; K united at base, deciduous, one sepal often 
spurred ; C usually 3 — 1, perigynous or epigynous ; 1 fertile sta. and 
staminodes; cpls. (3) each with 00 — 2 ovules with 2 integuments. 
Fruit indehiscent or a loculicidal capsule; no endosperm. Chief 
genus Vochisia. Placed in Polygalineae by Bentham- Hooker. 
Vouacapoua Aubl. = Andira Lam. 
Voyria Aubl. (incl. Leiphaiinos Cham, et Schlecht., Voyriella Miq.). 
Gentianaceae (1). 23 sp. trop. Am. and Afr. 
Vriesia Lindl. = Tillandsia Linn. 
Wachendorfia Burm. Haemodoraceae. 7 sp. Cape Colony. Trans- 
verse zygomorphism is found in the flr. but is not obvious on account 
of the twisting of the stalk. 
Wahlenhergia Schrad. (incl. Hedraeanthus Griseb.). Campanulaceae 
(1. 1). 80 sp. chiefly S. temp., where the genus to some extent 
replaces Campanula. 12 sp. are found in Eur. and As. Minor, one of 
which, W. hederacea Rchb. ( Campanula hederacea L.), the ivy- 
leaved bell-flower, occurs in Brit. Fir. like that of Campanula. 
Capsule loculicidal (the chief difference between these two genera). 
Waldsteinia Willd. Rosaceae (in. 6 c). 4 sp. N. temp. 
Walllchia Roxb. Palmae (iv. 6). 3 sp. Himal. to Malaya. 
Walsura Roxb. Meliaceae. 15 sp. Indo-mal. 
Waltheria L. Sterculiaceae. 30 sp. trop. Am. 
Warea Nutt. Cruciferae (1. 1). 2 sp. Florida. 
Washingtonia H. Wendl. Palmae (1. 2). 2 sp. S. Calif., Arizona. 
Included in Pritchardia in Nat. PJl .
