SCROPHULARIACEAE (FIGWORT FAMILY) 729 



bract-like alternate leaves, the root-leaves rounded and petioled, crenate. (Name 

 from (rtv, together, and Ovpis, a little door; in allusion to the closed valves of 

 the pod.) 



1. S. Bullii (Eaton) Heller. Hairy ; root-leaves ovate, heart-shaped ; spike 

 dense, 1-3 dm. long ; corolla greenish-white or yellowish, not longer than the 

 calyx, usually 2-3-parted. (S. Houghtoniana Benth.; Wulfenia Houghtoniana 

 Greene.) Oak barrens and prairies, Mich, to Minn., s. to O., Ind., 111., and 

 la. May, June. 



19. SEYMERIA Pursh. 



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. Anthers 

 approximate by pairs, oblong, 2-celled ; the cells equal and pointless. Capsule 

 many-seeded. Erect branching herbs, with the aspect of Gerardia; leaves 

 mostly dissected or pinnatifid, the uppermost alternate and bract-like. Flowers 

 yellow, interruptedly racemed or spiked. (Named for Henry Seymer, an English 

 naturalist.) AFZELIA J. G. Gmel. 



1. S. macrophylla Nutt. (MULLEIN FOXGLOVE.) Rather pubescent, 1-1.6 

 m. 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 at the apex ; style short, 

 dilated and notched at the point; capsule ovoid, pointed. (Afzelia Kzte.) 

 Shady river-banks, 0. to Neb., s. to Tex. July, Aug. 



20. GERARDIA [Plumier] L. GERARDIA 



Calyx bell-shaped, 5-toothed or 5-cleft. Corolla swelling above, with more or 

 less unequal lobes, the 2 upper usually rather smaller and more united. Stamens 

 hairy ; anthers approaching by pairs, 2-celled, the cells parallel, often pointed 

 at base. Style elongated, mostly enlarged and flattened at the apex. Capsule 

 globular or ovoid, pointed, many-seeded. Erect branching herbs (more or 

 less root-parasitic); stem-leaves opposite, or the upper alternate, the upper- 

 most, reduced to bracts and subtending 1-flowered peduncles, which often form 

 a raceme or spike. Flowers showy, pink, purple, or yellow, in late summer 

 and autumn. (Dedicated to the celebrated herbalist, John Gerarde.) 



1. DASYSTOMA [Raf.] Gray. Corolla yellow, the tube woolly inside, as 

 well as the anthers and filaments; anthers alike, awn-pointed at base; 

 leaves rather large, more or less incised or pinnatifid. 



* Pubescence partly glandular and viscid; corolla pubescent outside. 



1. G. pedicularia L. Annual or biennial, much branched, 1 m. or less high, 

 very leafy, villous at base, puberulent above ; leaves ovate-lanceolate, pinnatifid, 

 and the lobes cut and toothed ; pedicels glandular, about equaling the mostly 

 serrate slightly glandular or glabrate calyx-lobes. (Dasystoma Benth.) Dry 

 copses, Me. to Ont., Minn., and W. Va. 



Var. ambigens Fernald. Stems glandular-villous above ; pedicels and calyx 

 usually villous. Wise, to N. C. and Mo. Passing to the more southern var. 

 PECTINATA Nutt., with densely villous stems and leaves, and glandular-hispid 

 calyx. 



* * No glandular pubescence ; corolla glabrous outside; perennial. 

 1- Stems finely and closely pubescent. 



2. G. grandiflbra Benth. Minutely downy; stem much branched, 0.6-1 m. 

 high ; leaves ovate-lanceolate, even the upper ones more or less cut or pinnatifid, 

 the lower pinnatifid; pedicels rather shorter than the calyx; corolla 4-5 cm, 

 long, 4 times the length of the broadly lanceolate entire or toothed calyx-lobes ; 

 capsule glabrous. (Dasystoma Wood.) Oak opening* Wise, and Minn, to 

 Tenn. and Tex.
