Amsonia tomentosa

provided by wikipedia EN

Amsonia tomentosa is a species of flowering plant native to the southwestern United States (S California, S Nevada, Utah, Arizona, New Mexico, W Texas) and northern Mexico (Chihuahua).[1][2] Its common names include woolly bluestar and gray amsonia.

Amsonia tomentosa is a short, woody plant with many erect stems rarely reaching half a meter in height. The plant has two forms, a green glabrous (hairless) form, and a gray woolly form. The leaves are oval but pointed, and about 3 centimeters long. The flowers are white with a green or blue tint. They are tubular at the base and have flat faces with five petals. The flowers often come clumped in a cyme inflorescence. The fruits are podlike follicles that may separate into sections, each bearing a seed.

Varieties
  1. Amsonia tomentosa var. stenophylla Kearney & Peebles – Arizona, New Mexico, Utah, Texas, Chihuahua
  2. Amsonia tomentosa var. tomentosa – S California, S Nevada, NW Arizona

Uses

Among the Zuni people, a compound poultice of the root of the tomentosa variety is applied with much ceremony to rattlesnake bite.[3]

Amsonia tomentosa ( Norwegian )

provided by wikipedia NO

Amsonia tomentosa er en flerårig urt i gravmyrtfamilien.

Den blir 16–36 cm høy med mange opprette stengler, som er forvedet ved basis. Bladene er egg- til lansettformede, 2–4 cm lange og tilspissede i begge ender. De er sittende, eller har en kort bladstilk. Blomstene er hvite med et blått eller grønt skjær. Frukten er en 3–8 cm lang belgkapsel, som ofte deler seg i seksjoner med ett frø i hver.

Amsonia tomentosa er en typisk ørkenplante. Den vokser i sørvestlige USA (sørlige California, sørlige Nevada, Utah, Arizona, New Mexico og vestlige Texas) og i nordlige Mexico (Chihuahua). Plantene kan være ullhårete eller glatte. De sistnevnte er av og til blitt skilt ut som en egen art, Amsonia brevifolia, men det er ingen andre forskjeller.
