Including Capriola Adans., Dactilon Vill., Fibichia Koel.
Habit, vegetative morphology. Perennial. Culms 4–60(–100) cm high; herbaceous. Culm nodes glabrous. Leaf blades linear. Ligule present; a fringed membrane (very short), or a fringe of hairs.
Inflorescence. Plants bisexual, with bisexual spikelets. Inflorescence of spicate main branches; not comprising ‘partial inflorescences’ and foliar organs. Spikelet-bearing axes persistent. Spikelets solitary; secund.
Female-fertile spikelets, florets, fruit. Spikelets 1.7–3 mm long; compressed laterally; disarticulating above the glumes, or disarticulating between the glumes. Rachilla prolonged beyond the uppermost female-fertile floret, or terminated by a female-fertile floret (C. incompletus). Hairy callus absent. Glumes two; very unequal to more or less equal; shorter than the adjacent lemmas; awnless; carinate. Upper glume 1 nerved, or 1–3 nerved. Spikelets with female-fertile florets only (normally), or with incomplete florets. The incomplete florets (when present) distal to the female-fertile florets. Female-fertile florets 1. Lemmas entire; pointed, or blunt; awnless; carinate; 1–4 nerved. Palea present; relatively long. Lodicules present; fleshy; glabrous. Stamens 3. Ovary glabrous. Stigmas 2; red pigmented. Fruit small. Hilum short. Pericarp fused.
Photosynthetic pathway, leaf blade anatomy. C4; biochemical type NAD–ME (2 species); XyMS+. Midrib conspicuous; with one bundle only, or having a conventional arc of bundles. All the vascular bundles accompanied by sclerenchyma.
Taxonomy, distribution. Chloridoideae; main chloridoid assemblage. 10 species. Holarctic, Paleotropical, Neotropical, Cape, Australian, and Antarctic.
Anatomical references. This project.
