230 The Waterulies. 



16. N. alba X mexicana? (= N. tmrtiacea chromatello Marliac; A/, chroma- 

 tello Hort. ; N. tuberosa flavesccns of Kew) . Leaves orbicular, much blotched with 

 brown, 8 to 20 cm. across; when crowded they may rise as much as 20 cm. above the 

 water, and are not blotched. Flowers bright yellow ; petals numerous, broad, concave. 

 Very strong grower, but sterile. Said by Marliac to have the parentage cited above, 

 but believed by some to be N. tuberosa X mexicana. Structurally it bears some 

 resemblance to N. tuberosa, and sometimes the brown stripes of the petioles of this 

 species appear on the hybrid ; the question cannot yet be decided. Raised by Marliac 

 about 1888. 



17. N. alba rubra X mexicana? Several of the Marliac hybrids undoubtedly 

 have this parentage, but most distinctly N. robinsoni (N. robinsoniana Hort.), seig- 

 noreti, aurora, and fulva (= N. laydekeri fulva Tricker 1897). The leaves are much 

 mottled with reddish-brown as in N. mexicana. The outer petals are more or less 

 yellow, shading through rose to deep red on the inner ones; the stamens are red or 

 orange. Thus we have a beautiful blending of the colors of the parents. A7. robin- 

 soni is peculiar in having a crimped notch about the middle of each margin of the sinus. 

 There are also differences in the details of the coloring of the flowers. They were 

 first published in Revue Horticole in 1895, N. robinsoni and seignoreti with a colored 

 plate, p. 258, and the other two on p. 568. In the former article JV. andreana and 

 lucida (= N. laydekeri lucida Tricker 1897) are also mentioned, and in the latter 

 place is N. laydekeri fulgens with a colored plate. All are productions of Marliac. 

 AT. andreana appears on a colored plate in the same journal in 1896, pp. 352-353. The 

 last three also agree in having the leaves mottled with brown, but the yellow color is 

 not nearly so evident in the flower ; they may represent a second cross. N. chrysantha 

 (Marliac 1901) is described in almost the same words as N. aurora, and N. arethusa 

 (Henry A. Dreer Co. 1902) is spoken of as " an improved Laydekeri fulgens." 



Eu-castalia. 



(To N. alba we refer the following garden forms : A7. alba maxima; N. a. plenis- 

 sima; N. gladstoniana, raised by Richardson of Lordstown, Ohio; N. casparyi alba 

 Carriere, Rev. Hort. 1888, p. 300. To N. alba rubra belongs N. froebelii. To N. 

 odorata rosea we refer N. odorata rubra; N. rosacea; N. exquisita. To N. odorata 

 gigantea we refer N. gracillima alba Marliac Cat. 1901 ; N. caroliniana nivea Marliac 

 Cat 1901 ; N. eburnea Andre, Rev. Hortic. 1895, p. 568. To N. odorata minor belong 

 N. odorata pumila and N. union. To N. tuberosa we refer N. tuberosa richardsoni; 

 N. t. plena.) 



18. N. alba X Candida? (= N. alba candidissima Hort.; N. candidissima 

 Hort). A large, white, free-flowering variety ; very robust. Sterile. 



19. N. alba X odorata? (= JV. marliacea albida Marliac). The flower is pure 

 white, stamens yellow, sepals flushed pink ; fragrant. Leaves large, deep red beneath. 

 On account of the color of the sepals, and a tendency to pink on the stamens, the 

 pollen parent may have been N. 0. rosea, and the plant, in that case, belongs with 

 N. m. cornea and rosea (No. 20), which it resembles in every respect except color. 

 Sterile. Introduced by Marliac about 1889.
