It resembles AT. caerulea very closely and is generally sterile, though Caspary succeeded in fertilizing it with pollen of other individuals of the same stock and generation, and obtained a second generation of hybrids. These resembled those of the first genera- tion, except one individual, which produced styles as in N. capensis, and petals of a deeper color than those of either parent. The small violet-black spots on the calyx of N. caerulea are more plentiful in the hybrids. TV. pulcherrima (Tricker 1897) gives every evidence of having this parentage; the spotting of calyx and under side. FIG. 78.—NympTiaea, Pennsylvania. Sepal, petals, stamens, and section of ovary. Two-thirds natural size. of leaf, the purple margin of the leaf beneath, and the conical buds are reproduced as in N. caerulea. The sinuate leaves with acuminate lobes are like those of N. capensis. The color of petals and number of floral leaves are fairly intermediate. Sepals 4, petals 20 to 22, stamens 137 to 140, carpels 24. Sterile. (Fig. 77.) 3. (N.
