PURSLANE FAMILY. _Portulacaceae._

A rather small family, mostly American; herbs, usually with thick,

succulent leaves and stems, with flowers opening only in sunlight. They

usually have only two sepals, but the petals number from two to five

or more; the stamens are sometimes numerous, but when they are of the

same number as the petals they are opposite them; the one-celled ovary

is superior, becoming a many-seeded capsule. Pusley, or Purslane, is

one of the commonest garden weeds; everybody knows how difficult it

is to keep the spreading rosettes out of gravel walks, and we are all

familiar with the gaudy, ephemeral flowers of the cultivated Portulaca.

The Purslane-tree, or Spek-boom, of South Africa is often the principal

food of elephants and its foliage gives the characteristic coloring to

the landscape.

There are several kinds of Montia, closely related to Claytonia,

mostly natives of North America, rather succulent plants, very smooth

and often with a "bloom." The flowers are white or pinkish, with two

sepals; the five petals, equal or somewhat unequal, separate or more

or less united at base; the stamens five or three; the style branches

three; the capsule with three valves and one to three, shiny, black

seeds, which when ripe are shot out of the capsule by the elastic

closing of the valves.

The Indians gather these pretty succulent little plants for salad and

indeed the tender, bright-green leaves look as if they would taste very

nice. They grow in a loose bunch, with several stems, a few inches to a

foot high. The root-leaves have long leaf-stalks and vary very much in

size and shape, the earliest being long and narrow, like little green

tongues, but the later ones oval, round and kidney-shaped, and they

vary also in tint, in dry places being sometimes a dull yellowish-pink.

The stem-leaves are quite odd, for a single pair have united around

the stem and become a circular or somewhat two-lobed disk, one or two

inches broad, the stalk piercing right through its center. This leaf

forms a pretty, shallow saucer, with a small, loose cluster of tiny

flowers, on slender flower-stalks, springing from the middle. This is

common everywhere in orchards or vineyards, and in shady places in

the foothills and canyons, and has long been cultivated in England

for salad. It is also called Indian Lettuce and Squaw Cabbage. _M.

perfoliàta_ is similar.

This charming little flower resembles the Spring Beauty of the East,

_Claytonia Virginica_, and blooms in late spring, among the ferns and

wet grasses near the Yosemite waterfalls and in similar places. The

white flowers, about three-quarters of an inch across, are often tinged

with pink and the five stamens are violet. The tender stems, about

eight inches tall, are weak and almost trailing and the pale-green

leaves are smooth, the lower ones slightly thick and succulent, with

little bulblets in the axils, which drop off in drying; the capsule

mostly has only one seed.

There are several kinds of Claytonia, resembling Montia.

A pretty little plant, three or four inches high, with a juicy, reddish

stem and thickish, bluish-green, juicy leaves, the root-leaf narrow,

the two stem-leaves broader. The flowers, over half an inch across, are

white, tinged and delicately veined with pink, with a little yellow at

the base of the petals; the pistil and stamens pink; the two sepals

yellowish-green. This grows on moist mountain slopes, up to an altitude

of nine thousand feet, sometimes at the edge of the snow, is pretty and

delicate and also resembles the eastern Spring Beauty.
