11. LEPTURUS R.Br. 



Spikelets i-flowered, embedded in the hard, cylindric, articulate rachis, placed edgewise 

 thereto, the first glume wanting except on the terminal spikelet, the second glume closing the 

 cavity of the rachis and flush with the surface, indurate, nerved, acuminate, longer than the 

 joint of the rachis: lemma lying next the rachis, hyaline, shorter than the glume, 3-nerved : palea 

 hyaline, 2-nerved, a little shorter than the lemma ; rachilla not disjointing, the spikelet falling 

 entire, attached to its rachis joint. Low annuals or perennials, with hard cylindric spikes.

Rottbocllia re pens Forst. Prodr. 9. 1786. 



Monenna repens Beauv. Ess. Agrost. 117, 168, 177. 1812. 



Plants perennial, widely creeping, diffusely branching, the fertile culms ascending or erect, 

 as much as i meter tall, commonly shorter; sheaths glabrous; ligule membranaceous, about i mm. 

 long, ciliolate : blades flat, 10 to 20 or even 30 cm. long, as much as i cm. wide, glabrous on the 

 surface, scabrous on the margins, long-acuminate; spikes 5 to 15 cm. long, erect, strict, the 

 margins of the oblong hollows membranaceous, the internodes about 5 mm. long ; second glume 

 twice as long as the internode, coriaceous, ovate-lanceolate, acuminate, greenish ; lemma about 

 4 mm. long, pale, oblong-lanceolate, the margins incurved ; palea about as long as the lemma. 



This has not been observed on the main group of islands but is a common 

 shore grass on the islands to the south and extends to Australia and Ceylon. 

 Originally described from "Insulae intra tropicas," South Pacific.

Spikelets usually 2-flowered, sometimes 3 to 5-flowered, the rachilla prolonged behind the 

 upper floret, usually villous ; glumes somewhat unequal, acute, awnless, the second usually longer 

 than the first floret; lemmas usually short-bearded at the base, 2-toothed at the apex, the teeth 

 often awned, bearing from the back below the cleft apex a straight and included, or usually 

 bent and exserted, awn. Tufted perennials with flat blades and open or usually -contracted or 

 spikelike panicles.
