Description

Atriplex dioica is an annual herb which varies in appearance, growing erect up to 150 cm (5 feet) tall, with a greenish striate stem. The greenish or reddish leaves are lance-shaped to arrowhead-shaped and may exceed 8 centimeters (3.2 inches) in length. The male and female flowers are borne in small, hard clusters. [3]

Taxonomy

Atriplex dioica was first described as a species by Constantine Samuel Rafinesque in 1818. [1] It was subsequently described and named as Atriplex subspicata by Per Axel Rydberg in 1906 correcting an earlier description by Thomas Nuttall from 1818 where it was named Chenopodium subspicatum. [4] [5] As of 2023 Plants of the World Online and many prominent botanists including Jennifer Ackerfield and K.W. Allred consider the description by Rafinesque to have precedence and now classify it as Atriplex dioica. [1]

<i>Clintonia</i> Genus of flowering plants

Clintonia is a genus of flowering plants in the lily family Liliaceae. Plants of the genus are distributed across the temperate regions of North America and eastern Asia, in the mesic understory of deciduous or coniferous forests. The genus, first described by Constantine Samuel Rafinesque in 1818, was named for DeWitt Clinton (1769–1828), a naturalist and politician from the U.S. state of New York. For this reason, plants of the genus are commonly known as Clinton's lily. The common name bluebead refer to the distinctive fruit of members of the genus. Since fruit color varies somewhat across species, the common name bead lily is used as well.

<i>Atriplex</i> Genus of flowering plant

Atriplex is a plant genus of about 250 species, known by the common names of saltbush and orache. It belongs to the subfamily Chenopodioideae of the family Amaranthaceae s.l.. The genus is quite variable and widely distributed. It includes many desert and seashore plants and halophytes, as well as plants of moist environments. The generic name originated in Latin and was applied by Pliny the Elder to the edible oraches. The name saltbush derives from the fact that the plants retain salt in their leaves; they are able to grow in areas affected by soil salination.

<i>Urtica gracilis</i> Species of flowering plant

Urtica gracilis, commonly known as the slender nettle, tall nettle, or American stinging nettle, is a perennial plant plant without woody stems that is well known for the unpleasant stinging hairs on its leaves and stems.
