tribe Eragrostideae

Mediteranean Lovegrass (Pitted Lovegrass) Eragrostis barrelieri

This is a very opportunistic grass that has circled the globe.  It will grow where others will not.

Photos taken in Taylor County, Texas, June 2004

(Introduced, native to the Mediterranean - Taylor, Nolan, Callahan, Eastland, Runnels, Coleman, Brown)

Base: annual, clump grass, no rhizomes, no stolons (runner stem)

Blade (leaf): 1-5mm wide, 3-10cm long, mostly glabrous but with scattered hairs, tip edges roll inward

Sheath (leaf part encircling stem): glabrous with short hairs at throat, shorter than culm internodes

Culm (main grain stem): reclined, 20-55cm tall, branching at lower nodes

Inflorescence: open panicle 5-16cm long, 2-8cm wide, glandular spots or rings

Auxiliary Inflorescence: a few spikelets at the end of each sheath

Branch: ascending to spreading, wavy, not rebranching, 1.5-5.5cm long, glandular spots or rings

Spikelet: linear, 5-11mm long, 1-1.5mm wide, 6-15 flowers, on short pedicel

Lemma: reddish spots, conspicuous lateral nerves

 


 

                       

 

tribe Eragrostideae

Stinkgrass Eragrostis cilianensis

like E. barrelieri but the spikelets wider and are clustered on short branching branches.  Plant has glands on nearly all parts of the plant which produces a bad odor when crushed.

Photos taken in Taylor County, Texas, July 2007

(Introduced, native of Eurasia - Taylor, Nolan, Fisher, Coleman)

Base: annual, no rhizomes, no stolons (runner stem)

Blade (leaf): 2.5-7mm wide, 10-20cm long, flat or folded, gland pits on lower rib

Sheath (leaf part encircling stem): overlapping, glabrous, hairs at throat, gland pits in keel

Culm (main grain stem): 10-60cm tall, branching at base and nodes, often bend at node, ring of glands below node

Inflorescence: dense to open panicle 5.5-16cm long, 2.8-5cm wide, short branches

Spikelet: linear, flattened, 6-20mm long, 2-4mm wide, 12-40 flowers, on short pedicel

Glume: gland pits on keel

Lemma: conspicuous lateral nerves, gland pits on keel

 


 

 

tribe Eragrostideae

Red Lovegrass Eragrostis secundiflora var. oxylepis (Eragrostis beyrichii)

Photos taken in Taylor County, Texas, September 2007

(Native of Texas - Taylor, Nolan, Callahan, Eastland, Brown)

Base: perennial, no rhizomes, no stolons (runner stem)

Blade (leaf): 2-2.5mm wide, 10-15cm long, flat to edges roll inward, long hairs near ligule

Sheath (leaf part encircling stem): overlapping, soft hairs at throat and sometimes down margins

Culm (main grain stem): 30-75cm tall

Inflorescence: contracted panicle 5-30cm long, 1-15cm wide, spikelets clustered on short branches

Branch: mostly appressed, 1-14cm long

Spikelet: linear-oblong to ovate, flat, 6-20mm long, 3-5mm wide, 10-25 flowers, on short pedicel that disarticulates when mature

Glume: first 2.5-3mm long, second 3-4mm long

Lemma: 1.6-2.4mm long, about 1.2mm wide, strongly overlapping, pointed, awnless, straw to reddish-purple, conspicuous lateral nerves

Variation?

This specimen was cultivated from a native seed mix.  Its identity was difficult to determine.  The young spikelets are much rounder, more compressed, and the apex is not notched.
