2,i:-J10. R.H. 1S07, p. 32S. Var. azilrea, li^lit liluc, 

 and var. rdsea, pink, arc otherwiso like the type, but 

 upon carlior in tin- niorninji; they ronio up proniis- 

 ouously from sinnt of riic typo or of one another. — As 

 now onlt.. the var. zanzibarunsis shows the greatest 

 variation in color of sepals and petals, jis well as in 

 sha|H> and number of petals anil stajnens. The petals 

 vary from obovate lo elliptie-lanecolate. Colors shade 

 lR>m the det^p purplish bhie of the type to pale azure 

 on one hand, or to purple, pink, and ahnost red on the 

 other. The inner surface of the sepals varies from 

 greenish white to abiiost pure white, or shaded toward 

 the tip with pink, rwl, pale blue, or deep blue-purple. 

 All combinations of sepal anil petal coloring occur, 

 apparently without any correlation. Many of these 

 forms have been named, e.g.. Amethyst, L. Dittmann, 

 Kobald, Countess of \\'arwick, Lord Brooks, A^. Lislcrii, 

 A'. ;. riolacea. .V. i. arliKtina, etc. They can be repro- 

 duced true only by offsets. A small percentage of seed- 

 lings resemble the parents. 



10. xberolina, Uort .(N . cnpensis x N . zanzibnricnsis? 

 A', stcltiita, Berlin variety). Ia-s. somewhat peltate, 

 orbicular-ovate, strongly siiuiate, angle of lobes acumi- 

 nate; under surface dark purple; 8-16 in. across: fls. 

 deep blue, open 3-5 days, from 9 a.m. to 4 or 5 p.m., 

 6-S in. across; sepals green outside, blue within; petals 

 l.V-20, narrow, acute; stamens 60-100; appendage 

 blue. — Free bloomer, strong grower; sterile. Originated 

 many years ago in Germany, probably with Caspary. 



11. fllavo-virens, Lehm. (.V. gracilis of gardens, not 

 Zucc). Fig. 2.5.52. Lvs. narrowly peltate, deeply and 

 irregularly sinuate or nearly entire, suborbicular; angle 

 of lobes rounded; under surface pure green (or purplish 

 in hybrids); 1.5-17 in. across: &s. white, G-8 in. across; 

 sepals pure green; petals 16-20, acuminate; stamens 

 about 60, deep yellow; outermost filaments short, broad, 

 petaloid; anthers with long yellowish a])pendage. Mex. 

 — Crossed with A'. ciiiJenain var. zniizibaricnsis, this spe- 

 cies has yiekled a progeny showing much the same varia- 

 tion :is IS shown by A', zarizibnricnsis itself. These are 

 distinguished from forms of the latter by their more 

 slender and acute petals and sepals, and smaller number 



of floral parts. Tliey propagate easily from the tubers, 

 bloom very freely, and include the best of the tender, 

 day-blooming nyinpheas. The deepest blue is Gross- 

 herzog Ernst Ludwig; \Vm. .Stone is bright blue; Mrs. 

 C. W. Ward, pink; A', (imrilis rubra, red. Several other 

 named forms have been offered, e.g., Antoine Chaize, 

 A. Siebert, A^. gracilis rosea. 



25SI. Nympluea elegans. A blue Mexican water-lily. 



2552. Nymphaea flavo-virens. 



Of other member.s of Brachyceras, the following should be men- 

 tioned: jV. Hcudeldlii, Planch. Fl. 2-2 J^ in. across, pale blue; lvs. 

 2—1 in. Senegambia. — .V. callidntha, Conard. Fl. 4-7 in. across, 

 blue or pink; lvs. G-12 in. Cent. Afr. — A', sulfitrea, Gilg. Fl. 2-3 

 in. across, cadmium-yellow: If. 2-3 in. S. Cent. Afr. — A^. Sfuht- 

 nuinnii, Schw. Fl. 5-6 in. across, sulfur-yellow: If. 10-12 in. Cent. 

 Afr. The origin and relations of the true N. gracilis, Zucc are 

 uncertain; it is not in cult. 



Section II. Syncarpi^. 



SUBGENUS III. CASTALIA. 



A. Fls. yelloiv (Xanlhantha and hybrids). 

 B. Spreading by runners [natural .species). 



12. mexicana, Zucc. (C. mexicana, Coulter. A'^. flava, 

 Leitner). Floating lvs. ovate, margin obscurely and 

 finely sinuate, dark green above, beautifully blotched 

 with brown; under surface dark crimson-brown, with 

 .■^mall blackish dots; when crowded the lvs. rise 3-5 in. 

 above the water, arc orbicular, cup-shaped by overlap- 

 ping of the straight sinus-margins, entire, 3-5 in. across, 

 dark green and shining above, under surface bright 

 green, with fine purplish brown motthngs: fls. 4 in. 

 across, raised 4-5 in. above the water, bright canary- 

 yellow, open from 11 a.m. to 4 p.m.; petals 23, grading 

 in size and shape insensibly into the stamens, which are 

 about 50, light golden yellow: rhizome erect, tuber-hke, 

 discoid, plane beneath, 3-5 in. diam.; runners terete, 

 J^in. thick, white, rooting at the tip and sending up 

 lvs.; the young plant flowers in a few weeks and again 

 sends out" runners. Fla., Mex. B.M. 6917. Gn. 23:334; 

 27, p. 439; .52:445. — Hardy as far north as New York 

 "in 2 ft. of water, covered with boards and a few 

 leaves." Mexican stock is stronger and blooms more 

 freely than that from Fla. Rose considers them dis- 

 tinct species. 



BB. Without runners (hybrids). 



13. xodorata var. sulphtirea (A'', sulphitrea, Hort.). 

 Lvs. all floating, 4-6 in. across, like those of A', odo- 

 rata, but blotched with brown: fls. light yellow, 4-5 in. 

 across, borne 2-4 in. above the water; open during the 

 morning. One of Marliac's hybrids, doubtless A', mexi- 

 canaxN. odorala. Hardy. — A', odorata sulphitrea grandi- 

 flbra is a more recent and stronger-growing strain. 

 G.L. 24:.57. 



14. X tetragSna var. helvola (N. hclvola or -V. pf/gm^a 

 helvola ). Lvs. floating, oval, 3-4 in. across, similar in 

 shajie to those of A', ielragona, blotched all over with 

 brown: fls. floating, small, yellow, 2 in. across, open 

 during the afternoon. — Probably A^. mexicana x A". 

 Ielragona. Hardy.
