usually 4 in pairs or nearly equal and alternating with its lower 
lobes, or when the corolla is regular 4—8 alternating with its lobes. 
Anthers 2-celled, the cells opening longitudinally and usually parallel. 
Ovary not lobed or only shortly 4-lobed, usually more or less per- 
fectly. divided into 2 or 4 cells or half-cells, with 1 ovule in each 
cell or half-cell, either anatropous and erect from the base, or more 
or less amphitropous and attached laterally or near the top so as 
to appear pendulous. Style terminal, simple, entire or more fre- 
quently with 2 short stigmatic lobes. Fruit dry or more or less 
drupaceous, the whole. fruit or the endocarp separating into 2 or 4 
nuts or pyrenes or quite dehiscent. and 2 or 4-celled, and sometimes 
with an additional central cavity between the carpels having the 
appearance of a third or fifth empty cell. Seeds solitary in each cell 
half-cell or pyrene, erect, with or without albumen, the testa usually 
membranous. Embryo straight, with thick cotyledons and an inferior 
radicle. — Herbs, shrubs, trees or woody climbers. Leaves opposite 
whorled or rarely alternate, without stipules, entire, toothed or divided. 
Inflorescence various. 
A large Order, of about 800 species, ranging over both the New and 
the Old World, most abundant within the tropics, but with several extra- 
tropical species, both in the northern and southern hemispheres. Bitter or 
adstringent properties predominate in the family, but these can hardly be 
said to be of medicinal importance. The teak (Tectona grandis), the timber 
of which is so largely employed for shipbuilding, is the species of most 
economic importance. The genera Verbena, Lantana, and Clerodendron 
contain several well-known garden plants.
