NYMPH^A 



2555. Rootstock of Nymphsea tuberosa. 



belong here. N. tuberosa var. rubra of Sturtevant is a 

 red form of this type, probably (N. odorata rosea x 

 N. tuberosa) x N. alba rubra. 



22. tuberdsa, Paine (C. tuberosa, Greene. N. reni- 

 formis, Walt.?). Figs. 2554, 2555. Distinguished from 

 No. 17 chiefly by the numerous slenderly attached and 

 spontaneously separating tubers, 1-3 in. long on the rhi- 

 zome: Ivs. when floating less coriaceous than in No. 17, 



and more veiny 

 above; petioles 

 marked with longi- 

 tudinal brown 

 stripes; no purple 

 or red color about 

 Ivs. 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 Ivs. and 

 fls. rise 4-6 in. above the water; spreads rapidly by 

 tubers. Moderate bloomer. Garden forms are N. tube- 

 rosa robusta and Helen Fowler. Var. Richardsdnii ( = 

 var. plena) has many more petals than the type. R.B. 

 40:101. Var. maxima (N. odorata maxima, Hort.) is a 

 form with round Ivs. 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 Tren- 

 ton, N. J. 



cc. Lvs. crowded on the rhizomes; European species 

 and hybrids. 



D. Foliage green or reddish, not spotted with brown. 



23. Candida, Presl (N. biradidta, Somm. N. semia- 

 perta, Klinggraef. N. alba minor, DC. N. nitida, Sims?). 

 Similar to No. 24: line of insertion of the sepals angu- 

 lar, projecting downward: lowest pair of veins of If. 

 (veins of the lobes) curved toward one another: all of 

 the filaments broader than their anthers: fr. ovoid; 

 seed large. Cent, and N. Eu. 



24. alba, Presl (C. dlba, Woodv. & Wood). Lvs. 

 roundish, entire, floating, 4-12 in. across, red when 

 very young; lowest pair of veins straight and diverg- 

 ing: rhizome black: fls. white (in the type), 4-5 in. 

 across, open from 7 A.M. to 4 P.M. ; petals broad, ovate, 

 somewhat concave; angles of attachment of sepals 

 rounded; filaments of innermost stamens not wider 

 than the anthers: fr. more or less spherical; seed small. 

 Eu. and N. Afr. A robust species. In gardens, vars. 

 called Albatross, Harrisidna, Hermine, delicdta and 

 splendens may be found. Var. candidissima (var. max- 

 ima, var. plenissima) has Ivs. orbicular, lobes strongly 

 curved, overlapping, yellowish when very young: rhi- 

 zome brownish, sometimes 3 in. through: fls. large, pure 

 white, sterile. The first nymphea to bloom in spring, 

 continuing until frost. Very robust; a most desirable 

 white variety. 



25. Var. rfcbra, Lonnr. (C. dlba rubra, Lonnr. N. 

 dlba rosea, Hartm. N. dlba purpurea, Fries. N. dlba 

 sphserocdrpa rubra, Gasp. N. Caspdryi, Carr.). Outer- 

 most petals rosy, intermediate intensely rosy, inner- 

 most deep carmine-red; anthers and stigma yellow; 

 filaments and styles orange to deep red-brown; varia- 

 ble in depth and purity of color, deepening on second 

 and third days of flowering. Lake Fayer, Sweden. 

 B.M. 6736 (stamens poor). R.H. 1879:230. Difficult 

 to grow, requiring cool water and subdued sunlight. 

 About 15 named red water-lilies must be classed as 



forms of this variety. Var. Froebelii is the oldest of these 

 and least adapted to cult. Jas. Brydon, N. gloriosa, 

 Wm. Falconer and N. atropurpurea are favorites. See 

 also No. 27. 



26. alba x odorata r6sea. Fls. large, cup-shaped, often 

 raised above the water; petals broad, concave: Ivs. 

 large, dark green or purplish, rising above the water 

 when crowded. Robust, free-flowering plants, the color 

 growing paler as the fl. ages; sterile. Three groups may 

 be distinguished: (1) Fl. nearly white, flushed with 

 rose; N. Marlidceadlbida (Gn. 78, p. 373), almost white; 

 N. Gladstonidna, white; Goliath and N. lusitdna, very 

 large, rosy. (2) Fl. light pink; N. Marlidcea cdrnea, 

 flesh-color; Wm. Doogue, Mark Hanna, N. colossea (G. 

 34:609. G.M. 56:595). Leviathan, N. somptudsa are 

 very large forms, and very satisfactory. (3) Fl. rose- 

 color; N. Marlidcea rosea, N . nobilissima, James Hudson. 



DD. Foliage more or less flecked with brown. 

 E. Petals never tinted yellow; color deepening with age offl. 



27. alba rilbra x tetragSna. Rootstock usually erect 

 and unbranched: Ivs. small to medium size, dark green 

 above with irregular brown spots: fls. small to medium 

 size, pink or red. Several garden forms, differing in 

 size and color of fl., belong here: N. Laydekeri rosea, 

 fls. 2-3 in. across, pink changing to deep rose, opening 

 about 11 A.M.; N. Laydekeri rdsea prolifera, a many- 

 headed form. Of similar character, but larger in If. and 

 fl. (3-5 in. across) and colors from red to deep crimson 

 are N. Laydekeri lildcea, N. L. fulgens, N. L. lucida, N. 

 L. purpurea, N. L. rubra, N. Marlidcea ignea, N. M.fldm- 

 mea, N. M. rubra punctdta, N. sanguinea, N. Ellisidna, 

 Arethusa, Jas. Gurney, Jas. Brydon, Wm. Falconer, 

 Mrs. Richmond. 



EE. Petals, especially the outer ones, more or less yellow. 



28. alba rftbra x mexicana. Rhizomes erect: Ivs. 

 medium size (5-8 in.), brown-blotched: fls. 3-5 in. 

 across, light yellow with pink center to orange, or red 

 with yellowish tips and margins; the red color deepens

Redrawn from the old figure in Botanical Magazine (1804), show- 

 ing an historical picture of the true white Egyptian lotus. 



as the fl. grows older. N. Robinsonii is recognized by a 

 notch midway of the sinus of the If. N. Seignoretii, AT. 

 Andredna, N. aurora, N. chrysdntha, and N. Laydekeri 

 fulva are the older members of this group. With larger 

 fls. and clearer colors are the recent N. Indiana, Com- 

 anche, Sioux, N. solfatdre, N. graziella, Phebus, Phcenix, 

 Paul Harlot. In this group may be placed Arc-en-ciel, 

 Jean Forestier, N. formdsa, N. punicea.
