 edulis, DC. N. thermalis, DC., of the hot springs of 

 Hungary). WHITE LOTUS. Fig. 2556. Lvs. orbicular, 

 dark green above, under surface brownish, smooth or 

 slightly pubescent; diam. 12-20 in.: fl. white, the broad

 assigned the garden forms N. Ihermdlis with broad pet- 

 als and cup-shaped fls. from the hot springs of Gross-

 opening out horizontal; anthers longer than 



the filaments. Cent. Afr., Sierra Leone. 

 B.M. 4257. F.S. 627, 628. A.G.- 15:366. 

 N. dentata grandiflbra, N. d. magnifica, and 

 N. d. superba are large and floriferous 

 forms. 



SUBGENUS V. HYDROCALLIS. 



34. amazonum, Mart. & Zucc. Lvs. ovate, entire; 

 lobes rounded; upper and lower surfaces spotted 

 brownish or blackish, under surface reddish brown; 

 petiole with a ring of long hairs at the point of joining 

 the If. : fls. 3-6 in. across, imperfectly open 1 or 2 nights; 

 the bud opens about half and closes again between 3 

 and 6 A.M. the first night; the second night the sepals 

 and outer row of petals open about 7 P.M., the other 

 parts remaining as a tight, white bud until 3.30 A.M., 

 when the fl. opens fully from 4.30-5 A.M., then closes by 

 6.30 A.M. and draws down into the water; petals usually 

 20; stamens 93-297. Trop. Amer. B.M. 4823. 



35. Rudgeana, G. F. W. Mey. Lvs. elliptic to sub- 

 orbicular, 18 in. long, margin coarsely and irregularly 

 sinuate-dentate: fls. 3-6 in. across, imperfectly open 2 

 or 3 nights from twilight until dawn; usually only the 

 sepals and 4, 8 or 12 outer petals open, the remaining 

 parts forming a closed ovoid bud; occasionally a slight 



31. pubescens, Willd. Lvs. ovate, 10-12 ^ 

 in. long, dark green above, dull purplish green 

 and more or less pubescent beneath: fls. small

 triangular -excised, repand - dentate, thin and mem- 

 branaceous, 5 in. across, pilose beneath: fls. 2^-3 

 in. across; petals 7-8, ovate - lanceolate, acute. Cam- 

 eroon. A very distinct dwarf form, cult, in Germany; 

 probably not grown here. 



AA. Fls. pink or red. 



33. rfcbra, Roxbg. Lvs. orbiculate, reddish brown, 

 bronzy, becoming greenish, pubescent beneath, 12-18 

 in. across: fls. deep purplish red, 6-10 in. across, open 

 3 or 4 nights from 8 P.M. to 11 A.M.; sepals dull purplish 

 red, 7-nerved, never opening more than 10 above hori- 

 zontal; petals 12-20, narrowly oval, rounded at apex; 

 stamens about 55, cinnabar-red in color, becoming 

 brownish. India. B.M. 1280. F.S. 6:629. R.H. 1879, 

 pp. 74, 75. P.M. 11:265. This species varies much in 

 color, and produces fertile hybrids with N. Lotus and 

 N. L. dentata. There are, therefore, a series of gar- 

 den forms of all colors from delicate pink to deep pur- 

 plish crimson. In these the petals vary from broadly 

 ovate and concave to narrowly ovate and flat, and the 

 fls. are from tulip-shape to wide open. Some are highly 

 floriferous, others shy bloomers. Most of these are 

 arranged in order of color: fls. very delicate pink: N. 

 Smithiana, petals broad; N. indica I sis, N. Laelia, N. L. 

 colorans. Fls. light pink: N. delicatissima, N. Deanidna, 

 more pink, petals broad; N. Bouchedna, N. indica 

 Spira, Reine d'ltalie. Fls. rosy pink: N. kewensis (C. 

 L. A. 25, March, p. 35), N. Michelidna. Fls. red-pink: 

 N. Sturtevdnlii, fl. tulip-shape, very massive; N. rubi- 

 cunda, Hofgartner Graebner. Fls. magenta: N. Omar- 

 dna, fl. wide open, narrow petal; N. Ortgesidno-rubra, 

 N. Mdrias-Legrdngei, N. Bissetii, Adele, Niobe, AT. 

 tulipifera, small, tulip-shape. Fls. rosy carmine: Diana, 

 N. indica Brahma, N. rubra rbsea (B.M. 1364), N. 

 devoniensis (B.M. 4665), Fig. 2557, N. Arnoldidna, 

 Pres. Girard. Fls. carmine: N. Krumbiegelii, N. colum- 

 bidna, N. Diana grandiflbra. Fls. dark red: N. purpiirea, 

 Doctor Florenze, Geo. Huster. Fls. crimson to deep 

 purplish crimson: Frank Trelease, Rufus J. Lackland, 

 James Gurney, Jr. 



2557. Nymphaea devoniensis. 



Under No. 33.

 bud, which occurs before midnight; petals usually 16 

 20; stamens 43-83. Trop. Amer. 



36. blanda, G.F.W. Mey. (Not N. bldnda, Planch., 

 nor of gardens). Lvs. small, membranous, entire, sub- 

 orbicular; lobes slightly produced, subacuminate and 

 subhastate: fls. 4 in. across; habits of opening unknown; 

 petals 16; stamens about 65. Trop. Amer. 



In the Hydrocallis group are the following, known only in 

 herbaria: N. lasiophylla, Mart. & Zucc. Bahia, Brazil; N. Gardner- 

 idna. Planch. S. Brazil; N. JamesoniAna, Planch., Porto Rico and 

 Ecuador; N. stenaspiddta, Casp., Goyaz, Brazil; N. tenerin&nia,

Other nympheas occasionally met with are: N. Baiimii, Rehn. 

 & Henk., the smallest species known: fls. J^-l in. across, white, 

 slightly fragrant. S. W. Trop. Afr. N. eastonensis='N. Smithiana 

 X N. O'Marana. N. Henkelidna, Rehn. & Henk. Fls. strikingly- 

 flat, pale blue, having an odor of violets. Austral. N. Maynardii,

NYMPHOIDES (Nymphsea-like). Syn. Limndn- 

 themum. Gentiandceae. FLOATING-HEART. Ornamental 

 aquatic herbs. 



Perennial, fibrous-rooted, stoloniferous or proliferous, 

 with floating foliage: Ivs. ovate or orbiculate, heart- 

 shaped at the base, rarely peltate, with a closed sinus, 

 entire or slightly wavy: peduncles with 1, 2 or many fls.; 

 fls. white or yellow, in spring and summer, borne in the 

 axils or on filiform sts. apparently from the petioles; 

 corolla wheel-shaped, deeply 5-cut; lobes fringed or not; 

 stamens 5, fixed at the base of the corolla. Species about 

 20 in fresh water, in tropical and subtropical regions 

 around the world and reaching into temperate parts. 

 The generic name is in dispute, it having been known 

 heretofore as Limnanthemum. This genus and a very 

 few others are sometimes separated in the family 

 Menyanthacese, distinguished from Gentianaceae in 

 habit, in alternate or basal Ivs., and different aestivation. 



The floating-hearts of cultivation are most useful 

 ornamental aquatic plants, and are represented in culti- 

 vation by but four species. Nymphoides lacunosum is
