Nuphar advenum-One of the most common forms. Leaves about a foot wide, round to oblong, with a wide notch at the point where stem joins leaf. Blooms, 2 to 3 inches in diameter, have bright-yellow sepals touched with green or purple. Deep yellow or pale red stigma. Both blooms and foliage held above the water.



August Koch. One of Dr. Pring's earlier developments, and practically a "must" with most water gardeners. It is one of the few water-lilies which does well with comparatively little sun, and blooms freely, all winter long if taken indoors. Its fine fragrance is particularly noticeable indoors.

N. kalmianum-A much smaller species, with floating leaves no larger than saucers and a pale yellow bloom an inch or less in diameter. Spreads swiftly in the shallow water along the margin of a pool or river.

N. macrophyllum-Strong-growing southern species with bloom similar to that of N. kalmianum. Foliage, however, is large and ovate. One of the few members of the Water-Lily Family which will grow in running water.

N. minimum-Also known as Dwarf Pond-Lily. A very free-flowering species with tiny, pale yellow blooms and miniature floating leaves.

N. orbiculatum-A large and robust southern form with round, bright-green leaves somewhat fluted at the edges. Yellowish blooms about 2 inches wide. Stems and undersides of leaves covered with white down.

N. polysepalum-One of the largest of the North American species. Leaves are elongated, and the yellow bloom is 4 to 5 inches wide. Both blooms and leaves stand out of the water along shore, float in deeper water.
N. rubrodiscum-Also called Red Disk Pond-Lily. The elongated leaves range from 3 to 10 inches in length, float in deep water, stand erect in shallow. Yellow blooms, less than 2 inches in diameter, with conspicuous red centers
