Festuca elatior
Along roadside below our property, possibly also by road at top of hill; in full fl.
| | GEN | | tall, erect, few well-sep closely appress lvs |
| | LF | | narr (3-4mm), glab, 100% open sheath |
| | INFL | | tall narr pan, brs sp scaber, 1-brs 1-2 per node, spklts 1 per node |
| | SPKLT | | 13x3x1mm, lance, lat comp, 6 fls or so| gls | | 4mm and 5mm, 1 vein, keeled, scar marg, acute, glab |
| lem | | 8mm, 3 veins, min scaber awn to 1mm just bel tip between 2 v min teeth, midv sp scaber and maybe scaber-cil, not keeled, veins v faint, scar marg esp ab and teeth |
| pal | | 7mm, strongly 2-keeled, veins scaber |

I'd assumed it was
Bromus, but nothing matched after a exhaustive (but short) search through all available species in
RA&B (the
Wofford key really bites!), so I tried again, and came up with
Festuca, of course, which keys easily in
RA&B.
Along roadside I think; starting to fl.
| | LF | | 1-1.5mm wide, glab, scar aur present, trunc lig < 1mm |
| | SPKLT | | 10mm, 5 fls, low gl 2.8-3mm, up gl 3.7-4.1mm, lem 6.5-7mm, gls glab, lem scaber on midv at v top, 0.5mm scaber awn on some lemmas |
This must be a poorly developed or young version of
F. elatior.
Festuca obtusa
Very similar; from around pond or vicinity; in full fl.
| | GEN | | slender, erect, reddish bel |
| | LF | | flat, ~1.5mm wide, sp pil on blade ab and sheath, min or no aur, v min lig |
| | SPKLT | | 4-5mm, 1-3 fls, low gl 2.1-2.7mm, up gl 3.5-3.8mm, lem 3.5mm, gls scaber, lems glab |
