(PARSLEY FAMILY.) 



* * Tall and often stout ; leaves thick, not parallel-veined. 



2. E. Virgini&mim, Lam. Slender (1-3 high); radical and lower 

 stem-leaves linear- to oblong-lanceolate, on long (sometimes 1 long) Jistulous 

 petioles, entire or with small hooked teeth ; upper leaves sessile, spiny-toothed 

 or laciniate ; heads ovate-oblong (6" long), with spiny-toothed or entire reflexed 

 bracts, and bractlets with 3 spiny cusps (the middle one largest). Margins of 

 ponds and streams, N. J. to Fla. and Tex., near the coast. Aug., Sept. 



3. E. Leavenw6rthii, Torr. & Gray. Stout (1-3 high) ; lowest stem- 

 leaves broadly oblanceolate, spinosely toothed, the rest sessile and deeply 

 palmately-parted into narrow incisely-pinnatifid spreading pungent segments ; 

 heads ovate-oblong (1 - l' long), with pinnatifid spinose bracts and 3 - 7-cus- 

 pidate bractlets, the terminal ones very prominent and resembling the bracts. 



Dry soil, E. Kan., Ark., and Tex. 



# # # Prostrate and slender, rooting at the joints, diffusely branched, with small 

 thin unarmed leaves and very small heads. 



4. E. prostr&tum, Nutt. Lower leaves oblong, entire, few-toothed, or 

 lobed at base ; upper leaves smaller, clustered at the rooting joints, ovate, few- 

 toothed or entire (occasionally some additional trifid ones) ; reflexed bracts

36. SANICULA, Tourn. SANICLE. BLACK SNAKEROOT. 



Calyx-teeth manifest, persistent. Fruit globular ; the carpels not separating 

 spontaneously, ribless, thickly clothed with hooked prickles, each with 5 oil- 

 tubes. Perennial rather tall glabrous herbs, with few palmately-lobed or 

 parted leaves, those from the root long-petioled. Umbels irregular or com- 

 pound, the flowers (greenish or yellowish) capitate in the umbellets, perfect, 

 and with staminate ones intermixed. Involucre and involucels few-leaved.

 visions mostly sharply cut and serrate ; sterile flowers numerous and long-pedi- 

 celled ; fruit l - 2" long, the styles longer than the prickles. Throughout our 

 range, south to Ga. and Tenn., west to E. Kan. and Minn. May -Aug. 



Var. Canad6nsis, Torr., has comparatively few and short-pedicelled 

 sterile flowers, and styles shorter than the prickles. (S Canadensis, L) 

 With the last, but westward only to Minn, and E. Kan. 



ORDER 49. ABALlACE^. (GINSENG FAMILY )
