Description Erect small to robust perennials (sometimes short-lived or annual), forming dense tussocks, with or without rhizomes. Culms not noded or 1(2)-noded, slender, rigid, usually sulcate when dried, smooth. Leaves all basal and spirally arranged, or sometimes 1 or 2 cauline at nodes, with a well-developed blade, Mapania-type pseudopetiole absent; Oreobolus-type pseudopetiole present (obscure to obvious; Fig. 2); blade flat to channelled above, scaberulous or glabrous on the margins; sheath equitant or not; ligule absent. Lowest inflorescence bract erect, similar to the leaves, shorter to slightly longer than the inflorescence, upper bracts decreasing in length and often becoming glume-like, lamina linear. Inflorescence compound, paniculiform or subracemose, rather diffuse to dense, with several internodes, consisting of 2–10 distant fascicles of branches in the bract axils; branches 1–4 at each node, unequal, exserted from the sheath, rigid, flexuous, compressed, scaberulous or glabrous on the margins. Spikelets subsessile or pedicellate, in clusters of 2–24, usually 1-flowered, the rachis not elongated or flexuous. Glumes (floral bracts) 4–7, acute or mucronate, obscurely distichous, glabrous unless with sparse, minute prickle hairs along midrib; basal 2 or more glumes sterile; upper glume with a bisexual flower. Hypogynous bristles (3–)6, linear to lanceolate, margins with dense to scattered, white, short, antrorse, ciliate or ciliate-plumose hairs, persistent on the nutlet. Stamens 3; filaments glabrous; anthers twisted when dry. Style 3-fid, slender, of similar thickness throughout or slightly swollen at the base, deciduous. Nutlet narrow-ellipsoid to obovoid, with 3 whitish ribs, slightly reticulate-rugulose at 40? magnification, papillate or shortly hispidulous (glabrous in A. clarksonii) at the apex, otherwise glabrous. Photosynthetic pathway inferred from anatomy to be C3 [details]
