Meehan, Nat. Flowers, 1st Ser., 1, t 17. E. Jlavum, Smith; Eaf. 

 Med. Fl. fig. ob. The ^'E. Carolinianum, Walt." of Poiret, Roemer 

 & Schiiltes, etc., was based upon Walter's '■^ Anonymos, Erythronio 

 a^ni's?" which must have been Ucidaria inrfoliata. Damp open 

 woodlands and banks ; Nova Scotia to Ontario and Minnesota, and 

 south to Florida and Arkansas. 



2. E. 'ALBiDUM, Nutt. Leaves mottled : flowers white with more 

 or less of a bluish or purplish tinge, yellow within near the base, not 

 dotted, the segments strongly recurved, not at all auricled : stigmas 

 short (1 to H lines long), becoming recurved. — Similar localities; 

 eastern New York to Ontario and Minnesota, and south to Pennsyl- 

 vania, Virginia, Tennessee, and central Texas. The var. coloratum, 

 Sterns (Torr. Bull. 15. Ill), is the more deeply colored form. 



3. E. mesochoreTjJI, Knerr. Resembling the last, but the leaves 

 narrower (| to 1 inch wide) and not mottled ; segments of the peri- 

 anth not recurved ; capsule larger (6 to 15 lines long). — Grassy prai- 

 ries or wooded slopes, from western Iowa to central and eastern Kansas. 

 First noted, as a variety of E. albidum, by Mr. R. Buigess (Bot. Gaz. 

 2. 115) and Mr. M. H. Panton (same, 2. 123) ; perhaps well separated 

 from that species by Prof. E. B. Knerr (Midland College Monthly, 

 2. 5).
