Poison Sego—Zygadenus paniculatus.
Zygadene
Zygadènus élegans
White
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.
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.
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.
Zygadene—Z. elegans.
Death Camass—Zygadenus venenosus.
