 nearly straight line, opening by a common longitudinal cleft, rarely 

 subparallel. Nucules rounded at the apex. 

 Herbs or undershrubs of various habit. 



The name of this genus of jjlants comes from the Greek word irraxvi (stachiis'), a 

 spike, from the form of its stalk and leaves.

Rootstock somewhat woody, without elongated creeping stolons. 

 Stem wiry, erect (rarely decumbent), simple or rarely with a single 

 pair of branches. Radical leaves in tufts, on long stalks, oblong 

 or triangular-oblong, cordate, obtuse, crenate; stem leaves sessile, 

 oblonf or strapshaped-oblong, acute, crenate-serrate or serrate; all 

 ruo-ose. Lowest pair of bracts resembling the leaves; bracteoles 

 lanceolate-acuminate, as long as the calyx. \' erticillasters contracted 

 into an oblong spike, with the lowest verticillaster often sejiarate. 

 Calyx glabrous or subglabrous, except at the throat ; teeth as long as 

 the tube, deltoid, abruptly acuminated into subulate, spinescent. 

 Corolla tube usually twice as long as the calyx, much longer than all 

 the bracts, except the pair at the base of the spike. Plant green, 

 hairy or subglabrous.

 and o-enerally distributed in England. Rare in Scotland, and not
