Names
COLPODIUM Trin. [family POACEAE], Fund. Agrost.: 119 (1820)
Keniochloa Meld. [family POACEAE], in Svensk. Bot. Tidskr. 50: 538 (1956)
Information
Small perennials. Culms often becoming fibrous at the base. Leaf-blades flat or folded, blunt at the tip. Inflorescence a spiciform or spreading panicle. Spikelets 1–4(–6)-flowered, slightly laterally compressed, awnless; glumes persistent, equal or unequal, shorter than the lemmas or enclosing them, firmly membranous with hyaline margins and tip, lightly keeled near the base, rounded above, the nerves falling short of the obtuse or subacute tip; lemmas elliptic-oblong, thinly membranous, 3–5-nerved, keelless, glabrous or pubescent on the nerves and sometimes also between them with appressed clavate-tipped hairs, the nerves not reaching the obtuse or truncate tip; callus glabrous; palea as long as the lemma; lodicules 2–3-lobed.Species ± 20; on mountains from Turkey through the Caucasus and Iran to the Himalayas; northwards to the tundra; on the mountains of East Africa.
Notes
The African species were originally placed in Agrostis, from which they may be distinguished by the soft texture of their spikelets, by the awnless lemmas with nerveless tips, and by the clavate hairs often present on lemma and palea. Melderis transferred them to a new genus Keniochloa, which he compared with Zingeria P. Smirnov, a small Agrostis -like genus from Turkey and adjacent countries, which shares with them the unusual chromosome number of 2n = 8. Tzvelev, in Bot. Zh. 50: 1319 (1965), has since pointed out that Keniochloa cannot be satisfactorily separated from Colpodium. The genus as a whole has Poa -like spikelets, although a few of the species (including those from Africa) with 1-flowered spikelets and 3-nerved lemmas deviate considerably from the usual pattern in Poeae.
