Saskatchewan Species at
Risk Status:
Dichanthelium acuminatum var. fasciculatum is vulnerable because it is rare or uncommon in Saskatchewan and most local populations are small. No threats are known or anticipated for this species at the present time.
Height: 10 – 70 cm tall
Roots: fibrous
Stems: densely caespitose, ascending or spreading, nodes densely hairy, internodes purplish or olive to yellowish-green, distinctly papillose-pilose
Leaves: basal rosettes well-differentiated; cauline leaves 4 – 7, 5 – 12 cm long, 5 – 12 mm wide, ovate to lanceolate, short papillose-pilose above; sheath pubescent, shorter than the internodes; ligule hairy, to 3 mm long
Inflorescence: panicle 3 – 6 cm long, dense, rachis pilose
Spikelets: 1.5 – 2 mm long, lower florets sterile
Florets: glumes shorter than spikelets, subequal; sterile lemmas similar to glumes; fertile lemmas striate, chartaceous, indurate, shiny; fertile paleas striate
Fruits: caryopsis
Other: plants yellowish-green to purple; stems of autumn phase repeatedly branched and spreading, forming a dense cushion
