"
Calamagrostis sp. A" (Dorr 2014: 221).
Comments.
This taxon was first noted as "
Calamagrostis chaseae
auct., non Luces" by
Dorr et al. (2000
[2001]: 56) and subsequently called "
Calamagrostis
sp. A" in the Flora of Guaramacal (Venezuela): Monocotyledons (
Dorr 2014
) but its identity remains ambiguous and needs further study. The species habit is noted as stoloniferous, a habit not known from
Calamagrostis
or
Deschampsia
, which are tufted or very-short rhizomatous and tussock-forming. The mention of short spikelets (3-4.4 mm long), florets (appearing to) almost reach or equal the length of the glumes and 1-veined upper glumes in the brief description by
Dorr (2014
: 221) makes it possible that this taxon belongs to
Podagrostis
or
Agrostis
, although mention of a puberulent callus and presence of a fairly long awn (3.5-6 mm long) makes it less likely that this species is a
Podagrostis
.
