Achnatherum parishii ( الإنجليزية )

المقدمة من wikipedia EN

Stipa parishii, formerly classified as Achnatherum parishii, is a species of grass known by the common name Parish's needlegrass.[1] The Jepson Manual 2nd edition (2012) reclassified the plant as Stipa parishii var. parishii.[2][3]

Distribution

The bunchgrass is native to western North America from southern California and Baja California, through Arizona and Nevada, to Utah, where it grows in many types of habitat, especially chaparral and other dry habitats. It is found from 900–2,700 metres (3,000–8,900 ft) in elevation. Locations include the Peninsular Ranges, Mojave Desert sky islands, southern Sierra Nevada and High Sierra, Inyo Mountains, White Mountains, and Great Basin Desert mountains.

Description

Stipa parishii is a perennial bunch grass which forms tight tufts of erect stems up to about 80 centimeters tall.

The inflorescence is up to 15 centimeters long and packed with densely hairy spikelets. Each spikelet has an awn up to about 3.5 centimeters long. It has a single kink in it, whereas the awns of many other Stipa species have two kinks.

Distribución

Stipa parishii es nativa de Norteamérica occidental en el sur de California y Baja California, a través de Arizona y Nevada, a Utah, donde crece en muchos tipos de hábitat, especialmente chaparral en hábitats secos y otros. Se encuentra desde los 900-2,700 metros de altura. Las localidades incluyen las Sierras Peninsulares, las Islas del cielo en el Desierto de Mojave, en el sur de Sierra Nevada, Montañas de Inyo, White Mountains y las montañas del Desierto de la Gran Cuenca.

Descripción

Stipa parishii es una hierba perenne que forma matas apretadas de tallos erectos de hasta unos 80 centímetros de altura. La inflorescencia es de hasta 15 centímetros de largo y llena de espiguillas densamente peludas. Cada espiguilla tiene una arista de hasta unos 3,5 centímetros de largo. Tiene una sola torcedura en ella, mientras que las aristas de muchos otras especies de Stipa tienen dos dobleces.

Taxonomía

Stipa parishii fue descrita por George Vasey y publicado en Botanical Gazette 7(3): 33. 1882.[4]

Etimología

Stipa: nombre genérico que deriva del griego stupe (estopa, estopa) o stuppeion (fibra), aludiendo a las aristas plumosas de las especies euroasiáticas, o (más probablemente) a la fibra obtenida de pastos de esparto.[5]

parishii: epíteto otorgado en honor del botánico Samuel Bonsall Parish.
