 as those of the order. 



W. Idteum L. A magnificent flowering plant, frequent in the stagnant ■waters of 

 the South and "West ; in Sodus Bay, N. T. (WUliama) ; Lyme, Ct. ; near Philadel- 

 phia, etc. Ehizome creeping in mud in depths of water from 2 or 3 to 6£ From 

 this arise the simple scapes and petioles to the surface. Lvs. 10 — 18' diam., 

 orbicular, entire, concave, the petioles inserted at the center. Fls. several times 

 larger than those of Nymphaea odorata, fragrant. Petals concave, obtuse, light- 

 yellow, 3 — i' in length. The nuts imbedded in the torus are about the size of 

 acorns, and remarkable for the large, leafy embryo, Jmie (S.) — ^Aug. 



Order IX. NYMPHAEACEtE. Water Lilies. 



Herbs aquatic, with peltate or cordate leaves from a prostrate rhizome. Fls. large, 

 showy, often sweet-scented. Sepals and petals numerous, imbricated, gradually 

 passing into each other. Sep. persistent. Petals inserted upon the disk which sur- 

 rounds the pistil. Sta. numerous, in several rows upon the disk, often passing into 

 petals. Anthers adnate, introrse. Pistils many, united into a mariy-celled, many- 

 seeded, compound ovary with a radiate stigma. Sds. embryo inclosed in a sack at 

 the end of a copious albumen next the hUum. (Figs. 453, 232 — 240.) 



Genera 5, species 60, inhabiting the northern hemisphere, Victoria in equatorial America, 

 Their general aspect is that of an endogen, but they have 2 foliaceous cotyledons. The stems 

 of nyraphjEa contain a powerful astringent principle, which is removed by repeated "washing in 

 water, after which they are tasteless, and may be used for food.

 fragrance in the highest degree. Ponds and sluggish streams, N. Am. E. of R. 

 Mts. Ehizome thick, in mud where the water is of 3 — 8 or lOf m depth, send-
