* Leaves oval ; sinus fully one fourth to nearly half the length of the blade. 



H— Anther-cells usually nearly or quite as long as the filaments or exceeding them : stig- 

 matic disk 4 or 5 lines to nearly an inch in diameter, undulate margined, 12-22-rayed. 



N. polysepalum, Engelm. Very robust : petioles stout ; thin submersed leaves none or 

 at least not seen; floating leaves large, 8 to 12 inches long, 6 to 9 inches broad, with narrow 

 or closed sinus and very broad rounded basal lobes : the subglobose cup-shaped calyx 

 3 inches in diameter, when fully expanded even 4 or 5 inches broad ; sepals 9 to 12, yellow 

 or with a reddish tinge in age : petals 12 to 18, obovate, cuneate, truncate, half inch long, 

 two thirds as broad : stamens very numerous, red, recurved in age ; pollen yellow : fruit 

 subglobose, Xh, inches in diameter, with short stout definitely constricted neck and convex 

 umbonate 15-24-rayed stigmatic disk. — Trans. Acad. St. Louis, ii. 282, & Bot. Works,

 farinaceous seeds are an important source of food to certain Indian tribes. Here appears to 

 belong the N. W. American N. luteum of authors (Bong. Veg. Sitch. 124; Ledeb. Fl.

 with more highly colored flowers, having sepals margined with reddish brown and petals 

 deep red with yellow tips and bases. — Colorado, Pa/ry, and probably elsewhere with the 

 duller more yellow-flowered f(jrm. A form with smaller flowers (2 to 3 inclies in diameter), 

 in habit approaching the following, but with the characteristic dark red anthers of the 

 western species, has been collected in Lake County, Calif., Blankinship. 



N. advena, Ait. f. Stout but smaller in all parts than the preceding : rhizome horizontal, 

 thick : petioles usually ^ to ^ inch in diameter : thin submersed leaves present in seedlings, 

 but in tlie mature plant rare or none ; floating leaves broadly oval, often pubescent below ; 

 sinus usually open ; basal lobes very obtuse, sometimes rounded but usually more or less 

 triangular in outline : subglobose flowers If inches in diameter, when fully expanded 2 to 3 

 inches broad: outer sepals greenish; the inner commonly dull yellow: petals oblanceolate- 

 oblong, truncate, gradually narrowed toward the base : stamens in 5 or 6 series, recurved 

 with age, yellow : disk pale red, yellow, or green, subentire or undulate-margined ; stig-

2 Specimens subsequently collected by Nealley at Ptio Grande City, Texas, and by Pringle near 

 Brownsville, no. 1956, as well as specimens of Bourgeau and of Pringle from Mexico, agreeing well 

 with the Florida plant, may be referred to this species, as l)y Coulter, Contrib. U. S. Nat. Herb. i. 30. 

 Also Castalia Mexicana, Coulter, 1. c. ii. 12, apparently not Nymphma Mexicana of Zuccarini, which 

 should have white flowers.
