Diplachne

Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Tufted perennials. Leaf-blades flat or inrolled; ligules membranous, tapered-elongate, usually becoming lacerated. Inflorescence a slender panicle of several to many usually simple, spike-like branches. Spikelets dorsally compressed, 5–13-flowered, relatively long (>5 mm), breaking up at maturity; glumes 2, 1-nerved, subequal or the lower shorter, membranous, persistent; lemma 3-nerved, membranous, dorsally rounded or flat, truncate or bilobed, the midnerve exserted as a short mucro, nerves often fringed toward the base; palea shorter than lemma. Caryopsis dorsally compressed.

Two species from temperate and tropical Africa, America and Australia, sometimes naturalising outside this area. One species in Australia.

Clayton & Renvoize (1986) relegated the genus to Sect. Diplachne in the predominantly American genus Leptochloa, but Peterson et al. (2012) retrieved five genera from Leptochloa s.l.
