The gt-nius Xi/mpluTa divides itself readily into two 

 main divisions, which again are subdivided into five 

 subgenera ivs follows: 



Section I. Apocakpi.*:. Carpels free at the sides, 

 uniteii 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. — ^IVndcr day-bloomers: fls. on strong scapes 

 4-12 or 14 in. above the water {Lijtopknra, Casp.). 



Subgenus I. Ankcphya. Stamens all slender, half 

 as long as the petals, ahnost without any appendage 

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

 or white. — ^Two species, in N. Austral. 



Subgenus 11. Buachyceras. Outermost stamens 

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

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

 y(jHo^v_ — About 15 species in the tropics all around the 



world. , . 1 r I J. 



Seclion II. Syncakpi^. Carpels entirely fused to- 

 gether {Sytnphytopleura, Casp,). ^ . , . 



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 sUghtly wider than the 

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

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

 Temperate Zone, except ing the Pacific slope of N. Amer. 



Subgenus IV. Lotos. Sepals prominently vemed; 

 a space between the insertion of the petals and stamens; 

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

 pellary styles Unear: Ivs. sharply dentate: rhizome 

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

 or white on strong scape^s 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. IIydrocallis. Sepals not evidently 

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

 alternating circles of 4: stamens much as in Castaha, 

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

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

 About 9 species in Trop. .Vmer.

SUBGENUS I. ANECPHYA. 



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

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

 tate, sinus 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 fihform; anthers bright 

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

 •'8- 77' 34:63; 53:422 (var. Hudsoniana). Gn. W. 20, 

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

 15:511. Gn. 64, p. 114 (var. i/udsomi).— The most 

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

 genus. The original large-flowering type (sometimes 

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

 in gardens is smaller and ea.sier to manage; it is called 

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

 called N. gracilis. White and pink forms (N. alba and 

 V rdsea, Benth. & Muell.) occur in Austral. An Eng- 

 lish var. Hudsoniana, said to be a cross with A', stellala 

 is evidently only a seedling of N. gigantea. 



2 vioiacea, Lehm. (incl. A'^. Hbllzei, Rehn. & Henk. 

 N kehnellidna, Henk. N. Brbwnii, Bailey. A'. Bdnksii, 

 Cunn. Af. serrota, Muell. iV. repanda, Muell.). Smaller: 

 seijals marked with black Unes: lvs. wavy margined or 

 •diiiost 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. 

 Iclragbna by Baron von Mueller. 



SUBGENUS II. BKACHYCERAS. 



A. Lus. 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. 

 acro.ss, open 3 days from 8 a.m. to 1 p.m.; buds ovate; 

 sepals marked with black fines and dots; petals ovat^, 

 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 caeraiea, Sav. (C. cserulea, Woodv. & Wood. N. 

 slfMln, Gasp., etc.). Blue Lotus of Egypt Lvs. nar- 

 rowly peltate, oval, entire or shghtly 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 conica , 

 sepals thickly marked with black lines and dots; peta s 

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

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

 low; .appendage long (Ain. on outer stamens), pale 

 blue Egypt, N. and Cent. Afr. Ann. Mus. Pans, \ ol.
