-Pring. A new yellow of fine, clear hue and good form.

-Flowers reddish, lemon-chrome at the center and 6 to 10 inches across. Large, orbicular leaves, bright green on top, brilliant red with green veins beneath, with a wavy margin.

N. ampla-Tropical American species with white, star-shaped blooms, golden stamens

speciosa- The same, but not quite so small.

-Distinct coloring. Lavender-blue blooms brushed at petal tips with deep gentian-blue.

AUGUST KOCH-Pring. An old favorite, and a very good one with 7-to 8-inch blooms of pale violet, quite fragrant. Stamens are reddish-yellow; sepals lilac. A profusion of blooms the year around if plants are taken indoors in winter. One of the few water-lilies that do very well with a minimum of sunlight. Viviparous. Leaves are dark green and only 12 to 14 inches in diameter. Excellent for small pools. Very good for cutting.

A well established plant with fill a pool with dozens of blooms like these pictured, and their apple blossom fragrance makes them a favorite. Note, also, the bronzy-dark green foliage, another factor that makes the variety one of the country's most popular.

. Hybrid vigor appears in this big new primrose yellow. The first yellow variety that meets all the requirements of the grower. A good propagator and occasionally viviparous.

BAGDAD-Pring. Blooms of pale purplish-blue on short stems, just above the floating leaves. Viviparous.

-Often listed as Pennsylvania or N. pulcherrima. A cross from N. coerulea by N.capensis var.zanzibariensis. Blooms 10 to 12 inches across and are deep blue. A striking yellow disk in the center is surrounded by golden stamens with violet anthers. Dark-green leaves, with long, tapering lobes. and often more than 2 feet in diameter.

-Well-shaped blooms of deep blue. Viviparous.

BLUE TRIUMPH-Blue flowers up to a foot across, borne in great profusion. Green foliage flecked bronze.

-Large flowers, 10 to 14 inches across, of Campanula-blue with yellow center, similar to Mrs. Edwards Whitaker but fuller and more cup-shaped. Buds green, leaves large and orbicular, green above, red with green veins beneath.

N. Burttii-An interesting species first introduced into cultivation and identified at the Missouri Botanical Gardens in 1929 by Dr. Pring. Seeds, thought to be those of another species, were sent to the gardens from the Tanganyika Territory of East Africa by B.D.Burtt, a botanist engaged in research there. Of the several seeds planted, only one germinated, and in time produced spectacular 8-inch blooms, primrose-yellow, and very sweetly scented. An important find, because for many years N. stuhlmannii and N. sulfurea were thought to be the only yellow tropicals. The plant is still an enigma. Difficult to propagate and grow, but hybrids reproduce readily from tubers. The plant proved to be a new species when studied at the botanical gardens, and so was named for the discoverer.

Nymphaea gigantea hudsoniana is a beautiful blue tropical, and one of the freest in growth and bloom. It is a rich, deep color, with inner petals somewhat lighter and a cluster of golden stamens. "Without a doubt," writes Bissett, "the best of the tropicals."

N. calliantha-African species with light-blue or purple star-shaped flowers. Sepals are deep yellow.

-A variety just as unstable in hue. The flowers open either white or pale blue.

-Commonly called the Cape Blue Water-Lily. Blooms are 8 to 9 inches, a little deeper than sky-blue, with blue-tipped yellow stamens. Sepals are green outside. white flushed pale blue inside. Foliage is green, sometimes tinted purple. Fragrant. Grows freely throughout southern and eastern Africa. and in Madagascar.

forma rubra-A miniature with brilliant rose-colored blooms and a sweet scent. Excellent for tub culture.

madagascariensis-Madagascar variety similar to species type, but with much smaller blooms.

-Often listed as Royal Purple Lily. Similar to species type with rich purple-blue blooms and yellow stamens tipped navyblue. Fragrant. Free flowering. This variety has produced two garden hybrids which have become quite popular.

azurea-Like parent, but with delicate blue flowers.

rosea-Similar, but with deep rose-colored blooms.

-Pring. Striking hybrid in both size and coloration, obtained by Dr.Pring by crossing two forms of N. zanzibariensis rosea. Delicate pink blooms 8 to 10 inches across. Heart of the bloom is a breathtaking cluster of bright-pink anthers, held erect by yellow stamens. Fragrant. Large leaves, green mottled red and deeply notched.
