WATER-PLANTAIN FAMILY. _Alismaceae._

A rather small family, widely distributed, growing in fresh-water

swamps and streams. The leaves are all from the root, with long

sheathing leaf-stalks, and the flowers are regular and perfect, or with

only pistils or only stamens; the sepals three; the petals three; the

stamens six or more; the ovaries numerous, superior, developing into

dry, one-seeded nutlets.

There are a good many kinds of Sagittaria, with fibrous roots and milky

juice; the leaves are usually arrow-shaped; the lower flowers usually

pistillate and the upper ones usually staminate; the stamens are

numerous and the numerous ovaries are closely crowded and form roundish

heads. The name is from the Latin for "arrow," referring to the shape

of the leaves.

[Sidenote: =Arrowhead=

_Sagittària latifòlia_

=White

Summer

North America=]

An attractive and very decorative plant, with stout, smooth, hollow

flower-stems, from eight inches to four feet tall, with very handsome,

smooth, olive-green leaves and papery bracts. The flowers are about an

inch across, with delicately crumpled, white petals and yellow anthers,

forming a bright golden center, and the plants look very pretty

standing along the edges of ponds. The leaves are exceedingly variable

both in size and shape. This is found throughout North America. The

tubers are edible and hence the plant is often called Tule Potato, and

they are much eaten by the Chinese in California. The Indian name is

Wapato.

LILY FAMILY. _Liliaceae_.

A wonderfully beautiful family, large and widely distributed, mostly

perennial herbs, growing from bulbs or root-stocks, with perfect,

regular, symmetrical flowers and toothless leaves. The flower-cup

almost always has six divisions, the outer often called sepals and the

inner petals. The six stamens are opposite the divisions and sometimes

three of them are without anthers. The styles or stigmas are three and

the ovary is superior, developing into a three-celled capsule or berry,

containing few or many seeds.

There are several kinds of Anthericum, rather small, lily-like plants,

with grasslike leaves, springing from the base and surrounded by the

fibrous remnants of older leaves. The slender stems are leafless, or

have one, very small, dry leaf; the roots thick and fleshy-fibrous; the

flowers yellow, on pedicels jointed near the middle; the style long and

slender; the pod oblong, containing several flattened, angular seeds in

each cell. They are common in rocky soil, at altitudes of six thousand

to nine thousand feet, from western Texas to Arizona.

[Sidenote: =Amber Lily=

_Anthéricum Tórreyi_

Summer

Arizona=]

A beautiful little plant, with delicate flowers, unusual and pretty in

coloring. It grows from eight to fifteen inches tall and has a slender,

pale-green stem, springing from a clump of graceful, pale bluish-green,

grasslike leaves. The flowers are about three quarters of an inch long,

pale orange or corn-color, with a narrow stripe on each division; the

pistil green, with an orange stigma; the anthers yellow. The flowers

fade almost as soon as they bloom. This grows in open woods.

There are several kinds of Zygadene, natives of North America and

Siberia. They mostly have coated bulbs, resembling onions, and white

or greenish flowers, in clusters, the leaves long, smooth, folded

lengthwise and springing mostly from the root. The flowers are perfect

or polygamous, the six divisions alike, with one or two, greenish,

glandular spots at the base of each; the styles three, distinct;

the fruit a three-lobed capsule, with several or many seeds in each

compartment. The name is from the Greek for "yoke" and "gland," because

some kinds have a couple of glands on each division of the flower.

[Sidenote: =Poison Sego=

_Zygadènus paniculàtus_

=Cream-white

Spring, summer

Utah, Nev., Idaho=]

A handsome, rather stout plant, about a foot tall, with bright

light-green, smooth, graceful leaves sheathing the stem, which has a

papery bract around its base. The flowers are in clusters varying in

shape, sometimes growing in a long, loose raceme and sometimes in a

closer, pointed cluster. The divisions of the rather small, cream-white

flowers have short claws, with a yellow gland and a stamen at the

base of each. The stamens are conspicuous, with swinging, yellow,

shield-shaped anthers, and are at first longer than the three styles,

which gradually lengthen and, together with the stamens, give a

delicate, feathery appearance to the whole flower cluster. This grows

on dry hillsides and in meadows. The bulb is very poisonous.

Summer

U. S.=]

A handsome graceful plant, with one or more stiff stems, from six

inches to three feet tall, springing from a large clump of rather

stiff, bluish-green leaves, covered with a pale "bloom," and bearing

fine clusters of cream-white flowers, less than an inch across, their

divisions united below and adhering to the base of the ovary and each

with a sticky, bright-green, heart-shaped gland. This grows in moist

places in the mountains, across the continent.

[Sidenote: =Star Zygadene=

_Zygadènus Fremóntii_

Spring, summer

California=]

Much like the last, but the foliage with less "bloom" and the flowers

handsomer and rather larger. Their divisions are free from the ovary,

only the inner divisions have claws, and the glands are greenish-yellow

and toothed. This grows among bushes, on hillsides and sea-cliffs along

the coast.

[Sidenote: =Death Camass=

_Zygadènus venenòsus_

=White

Spring

Wash., Oreg., Cal.=]

Not nearly so handsome as the two last, but a pretty plant, from one to

two feet tall, with dull-green leaves, folded lengthwise, with rough

edges. The cream-colored flowers are less than half an inch across,

striped with green on the outside, their divisions free from the ovary

and all with claws, with roundish, greenish-yellow glands, not toothed,

and with long stamens. This grows in meadows and the bulb is very

poisonous except to hogs, so it is often called Hog's Potato.

There are several kinds of Veratrum, natives of the north temperate

zone; tall, perennial herbs, with thick, short, poisonous rootstocks;

stems tall and leafy, more or less hairy; leaves broad, plaited, with

conspicuous veins; flowers more or less downy, polygamous, whitish or

greenish, in a cluster, their six, separate divisions colored alike,

adhering to the base of the ovary, without glands, or nearly so, and

without claws; stamens opposite the divisions, with heart-shaped

anthers; styles three; capsule three-lobed, with several flat,

broadly-winged seeds in each compartment. Veratrum is the ancient name

for Hellebore.
