NYMPILEA 



a natural earth bottom are used for growing water- 

 lilies, care must be taken that noxious weeds do not get a 

 foothold. Cat-tails (Typha latifolia) and "tules" or 

 bulrushes are troublesome if not destroyed when they 

 first make their appearance. Palms, both fan-leaved 

 and feathery, giant bamboos, musas, strelitzias, papy- 

 rus, giant grasses, fatsia and caladiums are among the 

 things which can be used to ornament the surround- 

 ings of the water-garden. 



The genus Nymphaea divides itself readily into two 

 main divisions, which again are subdivided into five 

 subgenera as follows: 



Section I. APOCARPI.E. Carpels free at the sides, 

 united at their edges to the central column of the fl. and 

 at their backs to the receptacle: outermost stamens 

 ripening first, innermost last: rhizome ovate, stolo- 

 niferous. Tender day-bloomers: fls. on strong scapes 

 4-12 or 14 in. above the water (Lytopleura, Gasp.). 



Subgenus I. ANECPHYA. Stamens all slender, half 

 as long as the petals, almost without any appendage 

 (Fig. 2545): carpellary styles wanting: fls. blue, rosy 

 or white. Two species, in N. Austral. 



Subgenus II. BRACHYCERAS. Outermost stamens 

 with an appendage above the anther (Fig. 2546) : car- 

 pellary styles short, triangular: fls. white, blue, pink or 

 yellow. About 15 species in the tropics all around the 

 world. 



Section II. SYNCARPLE. Carpels entirely fused to- 

 gether (Symphytopleura, Gasp.). 



Subgenus III. CASTALIA. Sepals not evidently 

 nerved: carpellary styles flat, linear: outer stamens 

 petaloid; innermost stamens first to ripen, their fila- 

 ments short, narrower or but slightly wider than the 

 anthers (Fig. 2547). Hardy or half-hardy day-bloom- 

 ers: fls. white, pink, red or yellow. In the entire North 

 Temperate Zone, excepting the Pacific slope of N. Amer. 



Subgenus IV. LOTOS. Sepals prominently veined; 

 a space between the insertion of the petals and stamens; 

 stamens broad, flat, rounded at apex (Fig. 2548) : car- 

 pellary styles linear: Ivs. sharply dentate: rhizome 

 ovate, stoloniferous. Tender night-bloomers: fls. red 

 or white on strong scapes 3-12 in. above the water, 

 opening on 4 successive nights. Two or 3 species in S. 

 Eu. and Asia and N. and Cent. Afr. 



Subgenus V. HYDROCALLIS. Sepals not evidently 

 nerved: carpellary styles long, club-shaped: petals in 

 alternating circles of 4: stamens much as in Castalia, 

 all opening about the same time: rhizome ovate, stolo- 

 niferous. Tender night-bloomers: fls. creamy white. 

 About 9 species in Trop. Amer.

NYMPH^A 



INDEX, CONTINUED. 



SECTION I. APOCARPI.E. 



SUBGENUS I. ANECPHYA. 



1. gigantea, Hook. (Castalia gigantea, Brit.). Lvs. 

 narrowly peltate, elliptic or ovate, margin sinuate-den- 

 tate, siaus open; under surface brownish pink to purple; 

 18 in. across: fls. light blue, open 7 days from 9 A.M. to 

 6 P.M., 6-12 in. across; sepals pure green; petals 18-50, 

 dark blue at tip, shading to nearly white at base; sta- 

 mens 350-750; filaments mostly filiform; anthers bright 

 yellow. Austral. B.M. 4647. F.S. 7:751. G.C. III. 

 28:77; 34:63; 53:422 (var. Hudsoniana). Gn. W. 20, 

 suppl. Sept. 5 (var. Hudsonii). G.W. 1:122; 9:447; 

 15:511. Gn. 64, p. 114 (var. Hudsonii) .The most 

 delicate and lovely, and withal one of the largest of the 

 genus. The original large-flowering type (sometimes 

 called var. Hodkeri) is difficult to cult. The form now 

 in gardens is smaller and easier to manage; it is called 

 by Henkel AT. Caspdryi, and in Austral, is sometimes 

 called AT. grdcilis. White and pink forms (N. alba and 

 N. rosea, Benth. & Muell.) occur in Austral. An Eng- 

 lish var. Hudsoniana, said to be a cross with N. stellata 

 is evidently only a seedling of N. gigantea. 



2. violacea, Lehm. (incl. N. Holtzei, Rehn. & Henk. 

 N. Rehneltiana, Henk. N. Brbwnii, Bailey. N. Bdnksii, 

 Cunn. N. serrata, Muell. N.repdnda, Muell.). Smaller: 

 sepals marked with black lines: Ivs. wavy margined or 

 almost entire. Cape York Peninsula. A beautiful 

 white form of this is called "Eleonore." A very small 

 white one from Arnheim's Land was misnamed N. 

 tetragona by Baron von Mueller. 



SUBGENUS II. BRACHYCERAS. 



A. Lvs. entire or slightly wavy at base. 



3. elegans, Hook. (C. elegans, Greene). Fig. 2551. 

 Lvs. narrowly peltate, orbicular to ovate; margin 

 entire or with 5 or 6 small scattered teeth; under sur- 

 face dark purple; 7 in. across: fls. pale violet; 3-6 in. 

 across, open 3 days from 8 A.M. to 1 P.M.; buds ovate; 

 sepals marked with black lines and dots; petals ovate, 

 obtuse, 12-20; stamens stout, about 75, yellow; append- 

 age a mere tip; filaments broad. Mex., Texas. B.M. 

 4604. J.F. 2:180. G.F. 8:206 (adapted in Fig. 2551). 



4. casrulea, Sav. (C. cseridea, Woodv. & Wood. N. 

 stellata, Gasp., etc.). BLUE LOTUS of Egypt. Lvs. nar- 

 rowly peltate, oval, entire or slightly sinuate at base; 

 under surface green, with dark purple blotches, pur- 

 plish at margin, 12-16 in. across: fls. 3-6 in. across, 

 open 3 days from 7.30 A.M. to 12 M.; buds conical; 

 sepals thickly marked with black lines and dots; petals 

 14-20, lanceolate, acute, light blue above, basal half 

 dull white; stamens 50-70; outer filaments broad, yel- 

 low; appendage long (i^in. on outer stamens), pale 

 blue. Egypt, N. and Cent. Afr. Ann. Mus. Paris, Vol. 

 I C1802), p. 366 c.p. F.S. 7:653. Free grower and 

 bloomer but not showy. Forms occur in Afr. with pure
