2553. Nymphasa tetragona. 

 (XHD 



15. xMarliacea var. chromatella (N. chromatella). 

 Floating Ivs. orbicular, much blotched with brown, 3-8 

 in. across; when crowded, the Ivs. rise as much as 8 in. 

 above the water, are dark green above, lighter beneath; 

 petioles sometimes with longitudinal brown stripes: fls. 

 bright yellow, 3-6 in. across; petals numerous, broad, 

 concave; stamens deep yellow. Probably N. mexicana 

 xN. alba (or N, tuberosa). 

 Strong grower, free 

 bloomer; a general favor- 

 ite; perfectly hardy. 



N. Modrei (N. Moore- 

 ana) is very similar to N. 

 chromatella; believed to 

 be N. alba x N. mexicana. 

 Probably as second or 

 third hybrids of N. mexi- 

 cana may be placed here 

 Paul Harlot, clear yellow 

 with delicate shadings of 

 red at base of petals, and 

 Sioux, rich brassy yellow, 

 shaded red. Both have Ivs. 

 spotted reddish brown. 

 They show some inheri- 

 tance from N. alba var. 

 rubra (see No. 28). 



AA. Fls. white, rosy or red. 

 B. Rhizome erect: fls. white 



(Chamsenymphaea) . 

 16. tetragona, Georgi 

 (C. tetragona, Lawson. N. 

 pygm&a, Ait.). Fig. 2553. 

 Lvs. horseshoe-shape, en- 

 tire, the lobes diverging, 

 slightly produced and sub- 

 acute, dark green above, inclined to brown blotching, 

 reddish beneath, 3^4 in. across: fls. 1M~2H in- across, 

 open on 3 or 4 days from noon until 5 P.M..; base of fl. 

 square; petals 13-17; stamens about 40, yellow. E. 

 Siberia, China and Japan ; also in N. Idaho and Ont. B.M . 

 1525. G.F. 9: 134 (adapted in Fig. 2553). The smallest 

 nymphea in cult.; free bloomer; makes no side-shoots 

 from the single crown, but grows readily from seed. Seed 

 next to the largest of the genus. N. fennica, Mela, is a 

 form from Finland, and is offered by M. P. Andersen, 

 Jonkoping, Sweden. It runs into purple-fld. varieties. 

 Similar to N. tetragona and probably not 

 botanically distinct. Requires cold water. 

 N. vomerense is a small white water-lily, 

 said to be N. alba x N. tetragona. N. orien- 

 talis, is a miniature plant with shining 

 coppery green Ivs. Japan. N. himalayensis, 

 is smaller than the type. Himalayas. 



BB. Rhizome horizontal, or, if not, fls. 

 pink or red (Eucastalia) . 



c. Lvs. scattered loosely on the rhizome. 



17. odorata, Ait. (C. odordta, Woodv. & 

 Wood). SWEET-SCENTED WATER-LILY. Lvs. 

 nearly orbicular, entire, somewhat coriace- 

 ous, dark green above, purplish red when 

 young; under surface deep red to reddish 



treen or almost pure green ; diam. 5-10 in. ; lobes usually 

 iverging, but often touching or slightly overlapping; 

 petioles greenish or brownish: fls. (in the type) white, 

 3-5 in, across, open 3 days from 6A.M. till 12 M. ; sepals 

 green, tinged with reddish brown; petals 23-32, ovate 

 to lance-ovate; stamens 55-113, yellow; outer filaments 

 broad, white, petaloid; seed medium-sized. E. U. S., 

 common. B.M. 819 (small). Gn. 4, p. 368; 55, p. 179. 

 V. 2:196; 19:9. Varies greatly in size and color, ap- 

 proaching N. tuberosa. Garden forms selected for size 

 of fl. are called var. superba (N. superba, Hort.) and 

 N. lactea. 



18. Var. minor, Sims (C. odordta var. minor, Cock. N. 

 pumila). Lvs. deep red beneath (or green when aerial) ; 

 lobes diverging; diam. 2-5 in.: fls. white, 2J4-3J4 in. 

 across; sepals strongly purple-colored; petals 17-24; 

 stamens 37-78. Same range as type; often a shy 

 bloomer. B.M. 1652. A.G. 14: 112. Sometimes grows 

 where water recedes entirely in summer; usually in 

 shallow water. N. Union is a garden form. 



19. Var. r6sea, Pursh (C. odordta var. rosea, Brit. 

 Var. rubra, Hort.). CAPE COD WATER-LILY. Lvs. dark 

 reddish on both sides when young, becoming green 

 above: fls. pink, fading on the successive days of open- 

 ing, 4 in. across. Cape Cod, Mass. B.M. 6708 (too 

 pale). Var. exquisita is deeper in color of fl. and If., and 

 more easily grown. Vars. rosdcea, Jessiedna and Her- 

 mosa are forms of var. rosea. 



20. Var. gigantea, Tricker (C. odordta var. gigantea, 

 Fern.). RICE-FIELD WATER-LILY. Lvs. large, 12-16 in. 

 across, green beneath, at times tinged purplish toward 

 margin; edge often turned up; petioles green: fls. 4-7 

 in. across, pure white; sepals green; petals 24-31; sta- 

 mens 69-120. Del. to Fla., Mex., Cuba, Brit. Guiana. 

 In this may be included N. odordta latifolia, Harper, 

 N. ebiirnea, N. carolinidna nivea, N. gradllima alba, 

 and N. Parkeridna, Lehm. 



21. x caroliniana, Hort. (N. odordta carolinidna or 

 carolinensis. N. odordta superba, Rich. N. tuberosa 

 superba). Lvs. entire, 12 in. across, sinus barely closed; 

 green above, red beneath: fls. fragrant, 7 in. across; 

 petals narrow, abundant, delicate rosy pink: rhizome 

 stout. Believed to be N. odorata rosea x N. tuberosa. 

 The original type has given place to improved forms, 

 such as N. caroliniana perfecta, N. rosea, and N. sal- 

 monea (N. odorata perfecta and if. o. salmonea), N. odo- 

 rata Luciano (N. Luciana), N. odorata suavissima (N. 

 suavissima), N. odorata delicata, N. odorata turicensis, 

 and quite recently W. B. Shaw and Eugenia de Land. 

 N. Brakeleyi rosea (N. tuberosa rosea) and N. speciosa
