-t— -t— Cotyletlons ' incuniheut (parallel to the di.ssi'pimeni of the eapHule) ; mature fruit 



seldom exceeding 1^ lines in lon;,'th. 

 ++ Erect annuals with stem simple below: the first sjx-iies more or less pulxMccnt, the 



others nearly or cpiite glabrous, if granular very minutely so.

 be no doubt, from De CandoUe's accurate description, as well as from a tracing of and notes 

 upou the original iu herb. Brit. Mua. Plants appear, however, to have been early cultivated 

 at Geneva as L. Menziesii, which, being quite distinct, have led to a general confusion. 



Li, medium, Greene. Very similar to the preceding in flowers and fruit: root -' 

 more often branched, probably only of annual duration: stcna usually taller, boc 

 feet high : leaves lanceolate, dentate, but scarcely ever pinnatifid, nearly i«r (piitc ;rl
