Deathcamas
Deathcamas or death camas refers to several species of flowering plant in the tribe Melanthieae. The name alludes to the great similarity of appearance between these toxic plants, which were formerly classified together in the genus ''Zigadenus'', and the edible camases (''Camassia''), with which they also often share habitat. Other common names for these plants include deadly zigadene, hog potato and mystery-grass. *''Anticlea elegans'' – Mountain deathcamas *''Anticlea mogollonensis'' – Mogollon deathcamas *''Anticlea vaginata'' – Sheathed deathcamas *''Anticlea virescens'' – Green deathcamas *''Anticlea volcanica'' – Lava deathcamas *''Stenanthium densum'' – Pinebarren deathcamas *''Toxicoscordion brevibracteatum'' – Desert deathcamas *''Toxicoscordion exaltatum'' – Giant deathcamas *''Toxicoscordion fontanum'' – Smallflower deathcamas *''Toxicoscordion fremontii'' – Fremont's deathcamas, star zigadene - (several varieties) *''Toxicoscordion micranthum'' – ...

Melanthieae
Melanthieae is a tribe of flowering plants within the family Melanthiaceae. Molecular phylogenetics, Molecular phylogenetic studies in the 21st century have resulted in a large-scale reassignment of many of its species to different genera; in particular the genus ''Zigadenus'' (deathcamases) has been restricted to a single species, ''Zigadenus glaberrimus''. Plants contain alkaloids, making them unpalatable to grazing animals; many are very poisonous to both animals and humans. Description Like the family as a whole, members of the tribe are "lilioid monocots", i.e. their flowers superficially resemble those of the genus ''Lilium'', with six tepals not differentiated into sepals and petals. As with other lilioid monocots, they were previously included in a broadly defined family Liliaceae. They are found mainly in woodland or alpine habitats in the temperate regions of the Northern Hemisphere (North America, Central America, and Asia), with one species found in South America. They ...

Zigadenus
''Zigadenus'' is a genus of flowering plants now containing only one species, ''Zigadenus glaberrimus'', the sandbog death camas, found in the southeastern United States from Mississippi to Virginia. Around 20 species were formerly included in the genus, but have now been moved to other genera. Description ''Zigadenus glaberrimus'' generally grows to a height of . A total of 30–70 flowers are borne in panicles. Each white to cream colored flower is bell-shaped, across. The tepals of the flower remain attached to the fruit capsule when it forms. The cone shaped seed capsules are long by across. ''Zigadenus glaberrimus'' flowers from mid July to September. It is found growing in pine bogs, savannas and sandy pinelands in the US states of Alabama, Florida, Georgia, Mississippi, Virginia, North Carolina and South Carolina. Systematics The genus is a member of the family Melanthiaceae, tribe Melanthieae. Molecular phylogenetic studies in the 21st century have resulted in numb ...

Toxicoscordion Venenosum
''Toxicoscordion venenosum'', with the common names death camas and meadow death camas, is a species of flowering plant in the family Melanthiaceae. It is named for its well known toxic qualities, with both its common names and its scientific name referencing this. Because its nectar is also poisonous, it is mainly pollinated by the death camas miner bee, which specializes in collecting the toxic pollen for its young. It is native to western North America from New Mexico to Saskatchewan and west to the Pacific Ocean. Description ''Toxicoscordion venenosum'' is a bulb plant 20–70 centimeters tall when flowering in the spring or early summer. The underground bulbs are egg-shaped () and made of up of multiple layers protected by dried outer layers () like an onion. The plant's leaves appear very early in the spring and are narrow. Most of the leaves spring directly from the ground (basal leaves), though a few much smaller ones may attach to the flowering stem. The length of ...

Anticlea Elegans
''Anticlea elegans'', commonly known as mountain deathcamas, elegant camas, or glaucous death-camas, is a trillium-relative in the flowering plant family Melanthiaceae. Three distinct subspecies are included ''Anticlea elegans'' subsp. ''elegans'', the type subspecies, plus ''Anticlea elegans'' subsp. ''glauca'' and ''Anticlea elegans'' subsp. ''vaginata''. ''Anticlea elegans'' subsp. ''vaginata'' is likely a result of a vicariance event at the end of the Pleistocene and the populations are genetically drifting apart. Glacial refugia in at least five US states have formerly hosted populations of ''Anticlea elegans'' subsp. ''glauca'', though two are now extirpated. The species is native to most of North America, being absent from California and the Baja California peninsula, the deep southeastern United States, and the far north of Canada. Little is known about the species pollinators, with a small population in Idaho documented to be likely pollinated mostly by flies. Descripti ...

Camassia
''Camassia'' is a genus of plants in the asparagus family native to North America. Common names include camas, quamash, Indian hyacinth, camash, and wild hyacinth. It grows in the wild in great numbers in moist meadows. They are perennial plants with basal linear leaves measuring in length, which emerge early in the spring. They grow to a height of , with a multi-flowered stem rising above the main plant in summer. The six-petaled flowers vary in color from pale lilac or white to deep purple or blue-violet. Camas can appear to color entire meadows when in flower. Taxonomy and species Historically, the genus was placed in the lily family (Liliaceae), when this was very broadly defined to include most lilioid monocots., in When the Liliaceae was split, in some treatments ''Camassia'' was placed in a family called Hyacinthaceae (now the subfamily Scilloideae). DNA and biochemical studies have led the Angiosperm Phylogeny Group to reassign ''Camassia'' to the family Asparagac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Toxicoscordion Fremontii
''Toxicoscordion fremontii'', known as the common star lily or Frémont's deathcamas (after John C.

Toxicoscordion Paniculatum
''Toxicoscordion paniculatum'' is a species of flowering plant known by the common names foothill deathcamas, panicled death-camas, and sand-corn. It is widely distributed across much of the western United States, especially in the mountains and deserts of the Great Basin region west of the Rocky Mountains.

Anticlea Mogollonensis
In Greek mythology, Anticlea or Anticlia (; Ancient Greek: ''Ἀντίκλεια'', literally "without fame") was a queen of Ithaca as the wife of King Laërtes. Family Anticlea was the daughter of Autolycus and Amphithea. The divine trickster and messenger of the gods, Hermes, was her paternal grandfather. Anticlea was the mother of Odysseus by Laërtes (though some say by SisyphusHyginus, ''Fabulae'' 201; Plutarch, ''Quaestiones Graecae'' 43; Suida, s.v. Sisyphus''). Ctimene was also her daughter by her husband Laertes. Mythology Early years According to Callimachus, when she was young, Anticlea served the goddess Artemis, and accompanied her in hunting, bearing arrow and quiver. According to some later sources, including a fragment of Aeschylus' lost tragedy ''The Judgment of Arms'', Odysseus was the child of Anticlea by Sisyphus, not Laërtes. In this version of the story, Autolycus, an infamous trickster, stole Sisyphus' cattle. At some point, Sisyphus recognized ...
