Voandzeia— continued. 
V. subterranea (underground) Bombarra Ground Nut; Under- 
ground Bean. JZ. pale yellow, partly unisexual, partly perfect ; 
two upper calyx teeth or lobes connate; standard orbicular ; 
eduncles short, axillary, few-flowered. July. fr., pods irregu- 
arly sub-globose, two-valved. J. long-petiolate, pinnately tri- 
foliolate, stipellate. k. 3in. Tropics, 1823. 
VOCHISIA. See Vochysia. 
VOCHYA. A synonym of Vochysia (which see). 
VOCHYSIA (Vochy is the Guiana name of V. guian- 
ensis). Sometimes spelt Vochisia. Syns. Cucullaria, 
Strukeria, Vochya. ORD. Vochysiacem. A genus em- 
bracing about forty species of stove shrubs or often tall 
trees, inhabiting Brazil, Guiana, Eastern Peru, and New 
Grenada. Flowers yellow, odorous, rather large, in com- 
pound, elongated racemes or panicles; sepals five, connate 
at base, the posterior one large and often spurred; petals 
one to three, linear or spathulate, two of them smaller 
than the other; fertile stamen one; staminodia two; 
pedicels bibracteolate. Leaves decussately opposite or 
whorled, often coriaceous, sometimes prettily veined, as in 
Calophyllum; stipules small, subulate. Only a couple 
of the species have been introduced. Both are trees, 
thriving in a mixture of loam and peat. They may be 
increased by ripened cuttings, inserted in sand, under a 
glass, in heat. 
V. guianensis (Guiana) Copai-yé-wood. fl., spur spreading; 
racemes simple, erect, terminal, dense-Howered. August. 
l. opposite, obovate-oblong, shortly acuminate, glabrous on 
both sides. A. 12ft. and upwards. Guiana, 1822. (A. G. i. 6.) 
V. tomentosa (tomentose). fl., racemes terminal, loose, slightly 
nodding. August. J. opposite, oval-oblong, long-acuminate, 
attenuated at base, glabrous above, ferruginous-tomentose 
beneath. h. 25ft. Guiana, 1826, 
VOCHYSIACEZE. A small natural order of trees, 
often gigantie, with copious, resinous juice, rarely erect, 
sarmentose, or climbing shrubs, confined to tropical 
America. Flowers irregular, hermaphrodite, often large ; 
sepals five, free or connate at base, or rarely adnate to the 
ovary, the two outer ones often smaller, the two anterior 
larger, the posterior often largest, spurred or gibbous at 
base; petals hypogynous, or inserted on the top of the 
calyx tube, one, three, or rarely five, when one is pro- 
truded between the blade of the anterior sepals, clawed ; 
stamens inserted with the petals, usually fertile, the rest 
imperfect; filaments usually thick, excrescent, subulate ; 
pedicels jointed and bracteate; inflorescence variable. 
Fruit usually capsular, rarely a winged samara. Leaves 
opposite, whorled, or alternate, shortly petiolate, coriaceous, 
quite entire; stipules small, reduced to glands, or wanting. 
Branches usually opposite or whorled. The order em- 
braces seven genera, and about 100 species. Examples: 
Qualea, Trigonia, Vochysia. 
VOHIRIA. A synonym of Voyria (which see). 
VOLKAMERIA. A synonym of Clerodendron 
(which see). 
VOLEMANNIA. A synonym of Clerodendron

VOLUBLE. Twining round some support. 
VOUAPA (the Guiana name) Orv. Leguminose. 
A small genus (about three species) of stove, evergreen 
trees, natives of Guiana, now included, by Bentham and 
Hooker, under Macrolobiwm. Flowers racemose; calyx 
four-eleft, with two opposite, stipitate bracteoles at the 
base; petal one, flat; stamens three. Leaves unijugate. 
Only one species has been introduced. It thrives in a 
compost of sandy loam and a little peat. Propagation may 
be effected by ripened cuttings, inserted in sand, under 
a glass, in heat. 
V. bifolia (two-leaved). fl. violet; calyx lobes spreading; 
stamens nearly equalling the corolla; bracts elevated-uninerved. 
May. L, leaflets iin. ovate, acuminate, oblique. A. 10ft. 
1823. The proper name of this plant is now Macrolobium 
ifolium. 
VOUAY. A synonym of Geonoma (which see). 
VOYRIA. (Voyra is the Guiana name of one of the 
species), Syns. Humboldtia (of Necker), Leiphaimos, Lita, 
Vohiria. ORD. Gentianee. A genus comprising about 
sixteen species of dwarf, leafless, stove herbs, found 
growing on putrid wood and leaves in tropical America 
and (one species) Africa. Flowers white, yellow, orange, 
or rarely blue or pink, solitary or few in a cymose cluster ; 
calyx tubular or campanulate, four or five-toothed or 
lobed; corolla salver-shaped, with an elongated tube and 
four or five twisted, spreading lobes; stamens four or five, 
included ; filaments filiform or very short. Scales minute, 
opposite or the lower ones rarely alternate. The species 
are probably not now in cultivation. 
VRIESIA. Included under Tillandsia (which see). 
VULPIA. Included under Festuca.
