The weak stem is usually very crooked and is often prostrate on the ground; two linear-lanceolate leaves clasp it oppositely about halfway up. The opened flowers, somewhat less than an inch across, have five petals, two sepals, and five golden stamens that mature before the stigma. It is found in moist woods from Me. to Mich. and south to the Gulf.
(B) Purslane (Portulaca oleracea) (European) has a prostrate, juicy stem and thick, fleshy leaves; the latter are wedge-shaped with rounded ends. The stem is very branching and spreads or radiates from the root. The flowers are tiny, solitary, and yellowish, seated in the whorls of leaves that terminate the branches. Found in waste places anywhere and possibly indigenous in the Southwest.
WATER LILY FAMILY
(Nymphæceæ)
(A) Cow Lily; Yellow Pond Lily (Nymphæa advena) is not unattractive and is interesting in its makeup. The leaves are thick, rough, ovate, slit or lobed to the stem, which is long and hollow. The flower is raised above the surface of the water on a long, hollow stem. What appear to be six large green and yellow petals are in reality sepals; the real petals are numerous, stamen-like, inserted with the very numerous stamens under the golden-yellow rayed disk that forms the stigma. Very common in still or stagnant water.
(B) Water Lily; Water Nymph (Castalia odorata) needs no introduction to our readers. To my mind, it leads all other flowers in beauty, grace, purity, and fragrance. It is composed of four sepals, greenish on the outside and whitish within, and numerous pure, waxy-white petals. They sometimes are gigantic in size, often spreading five or six inches across. It flowers from June to Sept. in ponds or slow-moving water.
RANUNCULUS FAMILY
(Ranunculaceæ)
(A) Water Plantain (Ranunculus laxicaulis) is a rather common marsh-inhabiting Buttercup, with five to seven narrow yellow petals. The stem is stout but rather weak and angled, at each joint sending out a clasping lanceolate, almost toothless leaf. The flowers, which are about ¾ in. broad, are on long peduncles terminating the branching stem that rises from 1 to 2½ feet. It is found in bogs, ditches, and muddy places from Me. to Minn. and south to the Gulf.
(B) Marsh Marigold (Caltha palustris) is the very common marsh herb usually, but erroneously, called “Cowslip.” Its leaves are very commonly used and marketed for food. The flowers are perfect, have no petals but from five to nine (usually the former) golden-yellow, shining sepals, and numerous brighter stamens. The stems are hollow and furrowed. The leaves are round, kidney-shaped, usually with scalloped edges. Marsh Marigold is abundant in swamps or wet meadows from Newfoundland to Alaska and southward through the United States, flowering in April and May.
