Nymphaea tuberosa, Paine (C. tuberosa, Greene. N. reniformis, Walt.?). Figs. 2554, 2555. Distinguished from No. 17 chiefly by the numerous slenderly attached and spontaneously separating tubers, 1—3 in. long on the rhizome: Lvs. when floating less coriaceous than in No. 17, and more veiny above; petioles marked with longitudinal brown stripes; no purple or red color about Lvs. or sepals: fls. 4-9 in. across, pure white, open 3 or 4 days from 8 A.M. to 1 P.M.; petals broad, concave; seeds large (.44 cm. long). N. Cent. U. S. G.F. 1:366 (adapted in Fig. 2555), 367; 6:416 (good). Gn. 21:130; 52, p. 444. B.M. 6536 (poor).—A luxuriant grower; when crowded or in shallow water the Lvs. and fls. rise 4-6 in. above the water; spreads rapidly by tubers. Moderate bloomer. Garden forms are N. tuberosa robusta and Helen Fowler. Var. Richardsonii ( - var. plena) has many more petals than the type. R.B. 40:101. Var. maxima (N. odorata maxima, Hort.) is a form with round Lvs. and closed sinus, the lobes curved out at the apex to a short point; petioles pubescent, with long hairs, with a few faint longitudinal brown stripes: fls. medium to large, pure white, somewhat cup-shaped. Lake Hopatkong, N. J.—Rather smaller than the type; possibly N. tuberosa x N. odorata. A diminutive form of N. tuberosa occurs near Trenton, N. J.
