CENUS A7A'.— T E D C R I U M . Liu,,. 



Calyx tulnilar or cainpanulate, iroqurntly suhhilahiate, from the 

 )ij)|)onnoet tooth being more spreading than the others ; teeth 5, 

 generally not spinous-pointed. C'oroUa Buhunilaliiate; tube rather 

 short; upper lip very nhurt, slit down to the calyx tube; lower lip 

 3-lobed, the middle lobe larger than the others, and often notched: 

 from the splitting of the ujjper lip its segments appear to belong to the 

 lower lip, which thus seems to have 5 lobes instead of 3. Stamens 4; 

 filiiments subparallel, protruded through the slit in the upper lip; 

 anther-cells joined at the apex, and diverging nearly in a straight line, 

 ojiening by a longitudinal slit common to both. 



Herbs, undershrubs, or shrubs of various habit. 



This genua of jjlnnts is named in honour of Teucer, a medical botwnist, its disco- 

 verer. 



Section I.— CIIAMyEDRYS. Miinch. 



Yerticillasters 2 to G-flowcred, distinct (not approximate, so as to 

 form a distinct spike or head), ■with all the bracts, or at least the 

 lowest jiairs, like the leaves. Calyx of 5 nearly equal teeth, the 

 uppermost one not spreading.

Annual. Stein wiry, erect, generally branched at the base, and also 

 ])aniculately branched above; branches ascending-spreading. Leaves 

 all stalked, trifid, with each of the 3 segments cleft or trifid, or the 

 central one pimiatifid with 2 pairs of segments and a terminal one ; 

 idtimate segments strapshaped, entire, i)alcr and densely clothed with 

 glands beneath, and with the principal veins very ])rominent. l>racts 

 similar to the leaves, stiilked, the upper ones much smaller. Yerti- 

 cillasters 4 to 6-flowercd, arranged in a lax raceme, occupying the 

 greater part of the stem or branches. Calyx glandular-pubescent, 

 inflated, saccate at the base on the lower side ; teeth erect, deltoid- 

 triangular, nearly equal, half the length of the tube, minutely sj)inous- 

 mucronate. Corolla about twice as long as the calyx. Nucules tri- 

 gonous-subglobose, deeply pitted-honeycombed. Plant glandular- 

 pubescent.
