The genus Nelumbium embraces only two species, but specific names have been given to several varieties of N. speciostwi, the only distinction being in the colour of their flowers, which range from white and pale rose to deep rosy- pink, and in some instances there are a greater number of petals which impart a semi-double appear- ance. Neptunia plena (Water Sensitive Plant) is a curiously interesting subject with long, spongy, floating stems, bearing bi-pinnate leaves con- sisting of numerous small leaflets of a pale- green colour, which are irritable, as in those of the well- known Sensitive Plant, Mimosa pudica. The flowers are small, pale yellow, and arranged in globular heads on rather long peduncles, which are produced from the axils of the Fig. 611.—Nelumbium luteum. Ottellv ovalifoll\ is a compact and interesting Aquatic, with oblong-ovate leaves, some of which are submerged,- others floating on longer petioles. The flowers are borne above the surface of the water in a solitary spathe, the three large inner segments b'eing of a pale yellow colour. Philydrum lanuginosum.—A monotypic genus, the species being perhaps more interesting than beautiful. It is of biennial duration and of erect habit of growth, its lanceolate leaves being densely covered with woolly hair. The flowers are clear yellow, and are borne on long spikes. Height 2ft. to 3ft. PiSTLA. stratiotes (Water Lettuce).—A monotypic genus of the Aroid family. The species is a very handsome floating.
