Group 1 |
Single terminal spike, with spikelets having little or no stalk |
Major group. 37 species in our area: Cynosurus, Hordeum, Hordelymus, Gaudinia, Psilurus, Nardus, Mibora, Brachypodium, Vulpia, Micropyrum, Lolium, Elytrigia, Aegilops (Triticum), Elymus |
| Either:- |
Each node carries 2-4 spikelets, which are grouped in 2 rows.
|
or:- |
Each node carries 1 spikelet and a single floret
|
| or:- |
Each node bears 1 spikelet with several fertile florets
|
Still need to make 1-2 choices before determining genus/species |
Group 1a |
Each node carries 2-4 spikelets, which are grouped in 2 rows.
|
|||
| Either:- (Group 1a) | Inflorescence unilateral, fertile spikelets, and at the exterior, sterile spikelets (acting for protection), both with several florets. |
Cynosurus spp.: P. & A.
Genus identified. Consult FlorMed or other flora to determine which species |
|
|
| or:- (Group 1a) | Inflorescence in a dense distichous spike, 3 spikelets for each node, carrying one floret (sometimes a second aborted); middle florets -> glumes with short awns and lemmas with long terminal awns (group 1a) |
Hordeum spp.: A. & (P.)
Genus identified. Consult FlorMed or other flora to determine which species |
|
Group 1b |
Each node carries 1 spikelet and a single floret |
|||
| Either:- (Group 1b) | Lemmas with a long sub-terminal awn; lemma much shorter that the inter-node. No lower glume. .(group 1b) |
Psilurus incurvus: A.
Species identified. Congratulations! |
|
|
| or:- (Group 1b) | Lemmas with a long terminal awn; lemma much longer that the inter-node. No glumes. Spikelets inserted alternately in 2 rows along the axis .(group 1b) |
Nardus stricta P.
Species identified. Congratulations! |
|
|
| or:- (Group 1b) | Lemmas not pointed (without a terminal awn) ; glumes hide the florets .(group 1b) |
Mibora minima A.
Species identified. Congratulations! |
|
|
Group 1c |
Each node bears 1 spikelet with several fertile florets |
Look at the length of the glumes, whether the spike is on one plane (distichous), and finally the shape of the awns | |||
| Either:- (Group 1c) |
1 single glume, apart from the terminal spikelet |
Solid axis, inflorescence a dense distichous spike. Auricles at the base of the leaf blades |
Lolium spp. P. & (A.)
Species identified. Congratulations! |
|
|
| or:- (Group 1c) |
2 small but equal glumes |
2 equal glumes longly overtaken by several florets; solid axis, inflorescence in a lax distichous spike |
Micropyrum tenellum: A.
Species identified. Congratulations! |
|
|
| or:- Group 1c subsection (i) |
2 small unequal glumes
|
||||
| or:- Group 1c subsection (ii) |
2 longish equal glumes, spikes distichous
|
Group 1c subsection (i) |
2 small unequal glumes
|
|||
| Either:- | Glumes longly overtaken by the 3-12 florets ; lemmas with long terminal awns; spike unilateral (normamally, in our area) |
Vulpia spp.: A.
Genus identified. Consult FlorMed or other flora to determine which species |
|
|
| or:- | Short glumes with many florets; lemmas with terminal awns, +/- long; caryopsis velvety at the summit, spike neither unilateral nor distiquous |
Brachypodium spp.: P. & (A.)
Genus identified. Consult FlorMed or other flora to determine which species |
|
|
| or:- | Lemmas with a dorsal bent awn; spike distichous |
Gaudinia fragilis: A.
Species identified. Congratulations! |
|
Group 1c subsection (ii) |
2 longish equal glumes, spikes distichous
|
|||
| Either:- |
Supplementary awns surrounding the glumes (Triticum following FlorMed). Ligule often with 2 hairy auricles, axis deformed supplementary awns often long, glumes themselves with shorter awns, glumelles toothed or awned |
Aegilops spp. .: A.
Genus identified. Consult FlorMed or other flora to determine which species[Triticum spp. include wheat, rye, spelt - none of which are cultivated in our region] |
|
|
| or:- | Glumes similar in length to the several florets; deformed axis, inflorescence a loose distichous spike, long spreading rhizomes (in our area) |
Elytrigia spp.: P.
Genus identified. Consult FlorMed or other flora to determine which species |
|
|
| or:- | Like Elytrigia, but clump-forming, glumes awned and lemmas longly awned |
Elymus caninus : P.
Species identified. Congratulations! |
