approximated in pairs; cells similar or one smaller or sometimes larger 
and horn-like and sterile or nearly sterile; connective sometimes 
2-branched, each branch bearing a fertile cell or one branch with a 
fertile cell and the other with a disc-shaped appendage. Disc hypo- 
gynous, annular or unilateral, entire or rarely many-toothed, more or 
less prominent or in some genera obsolete. Ovary superior, sessile, 
entire, 2- (rarely 3- or very rarely 1-) celled; placentas central, adnate 
to the septum; style simple, entire or shortly 2-lobed at the apex, 
stigmatose at the clavate, narrow or capitate apex, or on the inside or 
margins of the lobes. Ovules numerous or several in each cell, rarely 
few, anatropous or amphitropous. Fruit superior, usually capsular, 
septicidal or loculicidal (sometimes both), or dehiscing by pores at the 
apex, rarely baccate and indehiscent. Seeds numerous, several or 
rarely few, sessile or nearly so; hilum basilar or lateral; funicle short, 
small or dilated ; testa sometimes membranous and adpressed, pitted, 
reticulate, scrobiculate, many-ribbed or rarely smooth, sometimes 
loosely-celled and hyaline; nucellus covered by a thin integument ; 
albumen fleshy, rarely thin or quite disappearing; embryo usually 
straight and searcely shorter than the albumen ; radicle turned towards 
the hilum.—Annual or perennial herbs, undershrubs or shrubs, rarely 
trees, glabrous, variously pubescent, or glandular-viscose. Leaves 
opposite (especially the lower), alternate or verticillate, entire, toothed 
or variously lobed or dissected; stipules 0. Flowers axillary or 1D 
terminal racemes, spikes, heads or panicles, racemosely or cymosely 
arranged ; pedicels ebracteolate or in some genera 2-bracteolate. 
Genera about 200; species about 2200, cosmopolitan, but most abundant in 
temperate regions, 
Cyclocheilon, Oliver in Kew Bulletin, 1895, 222, belongs to the Verbenace@. 
Zenkerina, Engl. in Engl, Jahrb, xxiii. 497, t. 10, figs. A-F, belongs to the 
Acanthacee. Hallier f. in Bull. Herb. Boiss, 2™e sér. iii., 202, refers it to Stauro- 
gyne, but Mr. C. B. Clarke, who has examined the pollen, regards it as @ new 
genus most nearly allied to Hemigraphis. 
Hiernia, 8S. Moore in Journ. Bot. 1880, 196 ; Engl. & Gilg in Baum, Kunene- 
Samb. Exped. 363, t. 8, is included amongst the Acanthacee in this work.
