274 Cl. VERBENACE (STAPF). | Cyclocheilon. 
bud. Stamens 4, didynamous, inserted low down in the corolla-tube ; 
filaments filiform, loosely villous upwards, the ‘anterior pair longer ; 
anthers almost enclosed in the throat, pendulous, cells more or less 
diverging, loosely hairy. Ovary entire, laterally compressed, perfectly or 
imperfectly 2-celled; carpels in the median plane; ovules 1 or 2 in 
each cell, subbasal, collateral, ascending, anatropous. Style long, fili- 
form; stigma entire, papillose all round. Fruit unknown.— Dwarf 
shrubs ; leaves opposite, small, hispidulous. Flowers solitary (repre- 
senting reduced cymes) in the axils of the leaves of very short branch- 
lets; pedicels finely filiform, 2-bracteate. 
Species 2, in Tropical East Africa and Tropical Arabia. 
Cyclocheilon was placed in Scrophulariacee by Oliver and Engler. The 
renewed examination of the type of the genus, and the discovery of a second species 
of which there is at Kew material much better than that on which the genus was 
based, has shown that the affinity of Cyclocheilon is with MNesogenes, DC., in 
Verbenacee.
