| 説明 | Green needlegrass is common in undisturbed open arid low elevation vegetation throughout Montana, but especially so in the eastern part of the state. This native bunchgrass also does well along roadsides and trail sides. The lemmas tip at the base of the awn is supposedly swollen, which is the main diagnostic trait of the genus Nassella (a segrated of Stipa). In reality, this species is very difficult to distinguish from the upland Stipa nelsonii (Columbia needlegrass, genus Achnatherum). Furthermore, green needlegrass hybidizes with diverse species of Stipa (in the broad sense). |
