5. Panicum brevifolium   L, Sp. Pl.: 59. 1753. ( Fig. 1C View Fig ).

Lectotypus (designated by CLAYTON & RENVOIZE, 1982: 496): INDIA: “ Habitat in India ”, s.d., Herb. Linn. 80.64 ( LINN!)   .

= Panicum mariae Steud., Syn. Pl. Glumac.   1: 419. 1854. Lectotypus (designated here): MADAGASCAR. Prov. Toamasina: Sainte Marie, “à Antharène”, III.1847, Boivin 1620 (P [ P02428363]!; isolecto-: G [ G00022451, G00022452, G00378073] images seen, P [ P00836145, P02251474]!; US [ US00074213, US000132970]!), syn. nov.

= Panicum bambusiusculum Stapf   in Bull. Misc. Inform. Kew 1919: 267. 1919. Holotypus: MADAGASCAR. Prov. Toamasina: Tamatave to Mahambo, 21.VI.1866, Gerrard 75 (K [ K000244689]!), syn. nov.

Creeping annual, rooting at lower nodes, to 1 m long, the culms glabrous, the nodes dark. Leaf sheaths largely glabrous with ciliate edges. Ligule membranous, truncate. Leaf blades ovate, flat, membranous, cordate and amplexicaul at base, 2– 6 × 0.6 –2.5 cm, drying yellow-green, cross veins visible when dry, glabrous to sparsely pubescent on both sides, with bulbous based cilia on the lower part of the margin. Panicles terminal, partly or fully exserted on a short peduncle, (2–)3–10(–13) cm long, ovate, the branches divergent at maturity, glabrous or with white cilia. Spikelets elliptic, asymmetric, apically apiculate, 1.6–1.8 mm long, with prominent veins, green or purplish, never gaping open. Lower glume as long as the spikelet, membranous, acute, 3-veined, glabrous to pubescent, separated from the rest of the spikelet by a swollen internode c. 0.3 mm long. Upper glume as long as the spikelet, herbaceous, 5-veined, glabrous to long-pubescent. Lower floret barren, with palea. Lower lemma herbaceous, 5-veined, glabrous. Upper lemma smooth, shiny.

Distribution and ecology. – African and Asian species, occurs on La Réunion and Mauritius, introduced to South America. Common across Madagascar except the south west, inhabits shady places in a variety of habitats: wet and dry forest understory and edges, grasslands, and roadsides, 0– 1500 m ( Fig. 2B View Fig ).

Notes. – Easily recognised by bulbous-based cilia on the cordate amplexicaul leaf bases, broad ovate leaves, and a long lower glume. Attractive and frequently collected. Trichomes on the upper glume elongate at maturity to enable dispersal.

JARVIS (2007: 720) confirmed the original lectotypification of Panicum brevifolium   L. by CLAYTON & RENVOIZE (1982: 496) even though VELDKAMP (1996: 189) erroneously cited the same sheet as a holotype. The lectotype sheet of P. mariae   was chosen due to its most complete label information and two type annotations by Camus; only one collection was cited in the protologue.

This species is illustrated in BOSSER (1969: Fig. 121a-f).
