Koeleria pyramidata
This genus is characterized by shiny spikelets in contracted spike-like
panicles. Spikelets are 2-4-flowered and slightly flattened. The hairy
rachilla generally projects beyond the last floret; glumes are broad and
only slightly shorter than the first lemma. Leaves are generally
in a basal clump.

Koeleria pyramidata (coo leh' ree ah py rah mih day' tah)
Synonyms: Koeleria macrantha, Koeleria cristata Common names: prairie junegrass, crested hair grass Origin and habitat: Native; dry prairies, sand-hills, and open savannas Identifying characters: A cool-season perennial with clustered stems as much as 5 dm tall (though usually only about 3 dm) and with a ring of felt-like hairs just below the upper nodes. Leaf sheaths are pubescent with blades generally scabrous and margins pubescent; with tiny ligules (up to 1 mm long). Spikelets are 2-flowered with acute awnless lemmas. The inflorescence opens widely for pollination, then contracts. Comments: This is a short-lived perennial and depends on reseeding for population sustainability. Prairie junegrass has high forage value during early stages. MAPS ADDITIONAL SPECIES IN MINNESOTA: None Next genus Return to technical key
