Hybrids and Garden Varieties. 231 



20. N. alba X odorata rosea? (N. marliacea carnea; N. m. rosea; N. Wm. 

 Doogue). Differs from No. 19 only in color of flower, which is from light pearly 

 pink to deep rose; all are strong, luxuriant growers but sterile. Under the first two 

 names it was introduced by Marliac about 1889; Wm. Doogue was obtained by Henry 

 A. Dreer Co. ten years later. 



21. N. alba X odorata rosea? (N. colossea Marliac 1901). Flowers and leaves 

 very large ; petals flesh colored. Blooms from early spring until frost. Sweet scented. 

 It may be a second hybrid, N. alba candidissima X odorata rosea. 



22. N. alba rubra X A large number of hybrids and variants have 



been introduced recently possessing the characteristic red shading of the Swedish 

 waterlily, and without distinct indications of other parentage. Perhaps N. Candida 

 has been used (as the flowers are often cup-shaped), or they may be second or third 

 or multiple crosses ; the latter is highly likely. Some of the types are fairly distinct, 

 even to an amateur, but most of them can be recognized only by the professional. In 

 N. marliacea Hammea, N. m. ignea, and N. gloriosa there is a faint blotching of the 

 leaf which can come only from N. mexicana or N. tetragona. We have not noted any 

 such character in N. ellisiana, sanguinea, marliacea rubra punctata, laydekeri purpurea, 

 Wm. Falconer, James Gurney, or James Brydon (= N. brydonacea elegans). 



23. N. odorata rosea X tuberosa? (= N. caroliniana, c. perfecta, c. rosea; N. 

 tuberosa superba; N. odorata caroliniana, 0. carolinensis, o. superba, o. luciana, 0. 

 suavissima). This hybrid is a much stronger grower than N. odorata rosea, but 

 otherwise resembles it. The cross easily occurs, but was first cultivated by Dr. Bahn- 

 sen of Salem, North Carolina, about 1890. 



24. N. tuberosa X odorata rosea ? ( = N. tuberosa rosea; N. brakeleyi rosea) . 

 Flowers pink. The plant has nearly the habit of N. tuberosa, but the rhizome is less 

 tuberiferous. N. tuberosa rubra (Sturtevant 1901) is said to be N. brakeleyi rosea X 

 N. rubra; but from the description it is more probably (TV. tuberosa X odorata rosea) 

 X alba rubra. The " rosy red " flowers and " bright red stamens " indicate this. The 

 plant was not flowering when I saw it in Mr. Sturtevant's garden (June, 1902) ; the 

 leaves were small, entire, and petioles dark red. 



Subgenus IV. LOTOS. 



25. N. lotus X rubra. Successive crosses between these species have been very 

 often made, and every possible gradation between them has been obtained. They differ 

 in color and size of leaf and flower and relative breadth of petal and degree of opening 

 of the flower; the hybrids vary also in texture of leaf and in distribution of color on 

 the petals. In N. sturtevantii the leaves are crimped at margin far more than in 

 either parent ; and the color of N. Geo. Huster is darker than any strain we have seen 

 of N. rubra. According to Focke (1881) N. rubra with N. lotus or ortgiesiana gives 

 the same product whichever is used as pollen parent, and the same is true of N. lotus 

 and dentata. But in N. rubra and dentata the hybrid progeny resembles the female 

 parent in respect to relative length and breadth of early leaves and floral leaves.
