bud. Stamens 4, didynamous, inserted low down in the corolla-tube ; 

 Ulaments 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 atid Tropical Arabia. 



Cyclocheilon was placed in Scrophulariacece by Oliver and Engler. The 

 renewed examination of the type of the genns, 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 Nesogenes, DC, in 

 Verhenacece.
