Calyx bell-shaped, deeply 5-cleft. Corolla with a short and broad tube, not 

 longer than the 5 ovate or oblong nearly equal and spreading lobes. Stamens 

 4, somewhat equal : anthers approximate by pairs, oblong, 2-celled ; the cells 

 equal and pointless. Pod many-seeded. Erect branching herbs, with the leaves 

 mostly opposite and dissected or pinnatifid, the uppermost alternate and bract- 

 like. Flowers yellow, interruptedly racemed or spiked. (Named by Pursh af-

 cent (4 -5 high) ; leaves large, the lower pinnately divided, with the broadly 

 lanceolate divisions pinnatifid and incised ; the upper lanceolate ; tube of the 

 corolla incurved, very woolly inside, as are the filaments except their apex ; 

 style short, dilated and notched at the point ; pod ovate, pointed. Shady river- 

 banks, Ohio, Kentucky, and southwestward. July. 



19. GERARDIA, L. GERARDIA. 



Calyx bell-shaped, 5-toothed or 5-cleft. Corolla bell-shaped-funnel-form, or 

 somewhat tubular, swelling above, with 5 more or less unequal spreading lobes, 

 the 2 upper usually rather smaller and more united. Stamens 4, strongly di- 

 dynamous, included, hairy : anthers approaching by pairs, 2-celled ; the cells par- 

 allel, often pointed at the base. Style elongated, mostly enlarged and flattened 

 at the apex. Pod ovate, pointed^ many-seeded. Erect branching herbs (clan- 

 destine root-parasites), with the stfcm-leaves opposite, or the upper alternate, 

 the uppermost reduced to bracts- and subtending 1 -flowered peduncles, which 

 often form a raceme or spike. Flowers showy, purple or yellow. (Dedicated 

 to the celebrated herbalist, Gerard.)
