Bromus vulgaris (above) versus Melica subulata (28359104506)

الوصف:

Description: These two morphologically similar understory grasses commonly co-occur. They both have fused leaf sheaths. They can be distinguished from each other by the generally drooping inflorescence of Bromus vulgaris versus the erect to ascending inflorescence of Melica subulata. Other differences include lemma awns over 5 mm long, and conspicuously hairy lemmas and leaf sheaths in Bromus vulgaris. Melica subulata in contrast lacks lemma awns (abeit the lemma tip is narrowly subulate) and the lemmas and leaf sheaths are glabrous or inconspicuously hair. Melica also has a corm stem base whereas Bromus lacks this feature. Date: 17 July 2016, 15:42. Source: Bromus vulgaris (above) versus Melica subulata. Author: Matt Lavin from Bozeman, Montana, USA.
