Astragalus drummondii ( Inglês )

fornecido por wikipedia EN

Astragalus drummondii is a species of flowering plant in the legume family known by the common name Drummond's milkvetch. The botanist Thomas Drummond first identified the plant during his travels in North America from 1825 to 1835, the year of his death. Astragalus drummondii is one of many plants named after him. Upon the return of samples collected by Drummond to England, his findings were published in Sir William Hooker’s Flora Boreali-Americana in 1840.[1]

Distribution

Astragalus drummondii is found widely across the American west and Saskatchewan, Alberta, and British Columbia. Its distribution has not changed appreciably since the species was first identified.

A. drummondi distribution

Habitat and ecology

A. drummondii is a hardy plant that can live in a range of different climates. It flourishes in dry, light soil as well as moderately wet soils. While it grows the most plentifully on grasslands, it can also survive in oak and pine forests. It tends to collect on hillsides when present.

Morphology

A. drummondii

Individuals of this species are herbaceous perennial plants with thick, hairy stems as well as long-hairy foliage. The plant tends to have several large stems diverging near to the ground. The plant is often 40 to 70cm tall. It has pinnately-compound leaves 6 to 14cm in length. [2]

Flowers and fruit

Flowers of Astragalus drummondii are white and 18 to 25mm long. The flowers are usually toward top of the plant, above most of the leaves. The flower's keel can sometimes be purplish in color. The sepals are small, hairy, and about 8mm long. The plant flowers in June and July. The plant has drooping hairless pods roughly 4cm long. The pod is deeply grooved along the under side (a key trait).[3]

Herbivory

Many species in the genus Astragalus are toxic. Cattle that consume Astragalus may act "crazed", and even dying. This had led the genus to be known as "locoweeds". There are three major groups of the toxicity, those that sequester selenium, those that make nitrotoxins, and those that make swainsonine (a poisonous alkaloid). Samples of A. drummondii in New Mexico were tested and found to be negative for the production of swainsonine, suggesting that this species may be safe for cattle to eat.[4]

Descripción

Son plantas herbáceas perennes, caracterizadas por tener tallos gruesos, peludos, así como follaje peludo. La planta tiende a tener varios grandes tallos divergente cerca de la tierra. La planta suele ser de 40 a 70 cm de altura. Se caracteriza por hojas oblongas de 6 a 14 cm de longitud, que son muy peludas en su lado envés. Las plantas a menudo tienen flores largas de 18 a 25 mm de estructuras alargadas blancas. Las flores se encuentran por lo general en la parte superior de la planta, por encima de la mayoría de las hojas. La quilla del flor puede ser a veces de color púrpura. Los sépalos son muy pequeñas estructuras peludas unos 8 mm de largo. La planta florece en junio y julio. La planta se caracteriza por la producción de vainas caídas sin pelos de más o menos 4 cm de largo. Costura de la vaina es lo suficientemente gruesa que casi forma una partición entre las semillas.[1]

Ecología

Muchas especies del género astrágalo son venenosas. El ganado en las áreas en las que el astrágalo está presente se ha sabido que luego de consumir la planta, actúan enloquecidos poco antes de morir. Hay tres grupos principales dentro del grupo venenosa, los que secuestran el selenio, los que hacen nitrotoxinas y los que hacen swainsonina (un veneno alcaloide ). Cuatro grupos de A. drummondii en Nuevo México fueron analizados y se encontró que eran negativos para la producción de swainsonina, lo que implica que esta especie es segura para el pasto de ganado.[2]

Distribución

Es una planta herbácea perennifolia que se encuentra en Estados Unidos y Canadá.

Taxonomía

Astragalus drummondii fue descrita por William Jackson Hooker y publicado en Flora Boreali-Americana 1(3): 153–154, pl. 57. 1831.[3]

Etimología

Astragalus: nombre genérico derivado del griego clásico άστράγαλος y luego del Latín astrăgălus aplicado ya en la antigüedad, entre otras cosas, a algunas plantas de la familia Fabaceae, debido a la forma cúbica de sus semillas parecidas a un hueso del pie.[4]

drummondii: epíteto otorgado en honor del botánico Thomas Drummond.
