Description
Genus Elymus
Plants
perennial
, usually tufted
, usually without, rarely with, rhizomes. Culms
usually erect
. Leaf sheath
of cauline leaves split almost to base
; auricles
present or absent; leaf blade flat or rolled. Spike erect to nodding
. Spikelets
1 or 2(4) per node, sessile, rarely very shortly pedicellate
, appressed
to rachis, clearly laterally compressed
, usually all similar, with 210 or more florets
; rachis tough. Glumes
opposite or side-by-side, linear-lanceolate to lanceolate-ovate, firmly membranous to leathery, 19(11) -veined, not keeled
, apex obtuse
to shortly awned
; veins ± raised. Lemma lanceolate-oblong, rounded
abaxially, 5-veined, ± pubescent
, apex obtuse or acute to awned, rarely toothed
; veins connivent at apex; awn
erect or reflexed
. Palea shorter than or equaling lemma, apex retuse
, subrounded, or acute. Caryopsis usually adherent
to lemma and palea. x = 7.
About 170 species:temperate regions of both hemispheres, mainly in Asia; 88 species (62 endemic) in China.
The genus Roegneria should be referred to Elymus because of their many common characters, e.g.
, plants usually tufted; spikelets usually all similar, 1 per node; lemma lanceolate-oblong, rounded abaxially, 5-veined, veins connivent at apex.[1]
Physical Description
Species Elymus ciliaris
Culms solitary or tufted , usually geniculate at base , sometimes erect , 40-130 cm tall, 1-5 mm in diam. Leaf sheath glabrous , or pilose at base; leaf blade flat, 9-25 × 0.3-1 cm, glabrous to scabrous , pilose or pubescent , or densely so. Spike erect or nodding , 10-22 cm; rachis scabrous, margin hispid . Spikelets 1(or 2) per node, green, 10-22 mm excluding awns , with 5-12 florets . Glumes oblong-lanceolate or elliptic-lanceolate, proximal one 6-11 mm, distal one 7-13 mm, 5-7-veined, scabrous, ciliate , or white hirsute along veins and margin, apex acute, acuminate, or pointed . Lemma oblong-lanceolate or oblong , scabrous to hispid or both, margin shortly ciliolate to long ciliate, apex pointed or awned ; first lemma 7-12 mm; awn often reflexed , 1-30 mm. Palea oblong-ovate, much shorter than lemma, scabrous or ciliolate along keels distally, apex truncate . Fl. and fr. May-Jul. [source]
