{Codachyrum, Nees, 1842; Erochlae Rafin, 1825; Exagrostis, Steud., 

 1840 ; Harpachne, Hochst, 1841 ; Macroblepharus, Ohil., 1857-8 ; Megastachya, 

 Beauv., 1812). 



Love Grasses. Generally good pasture grasses. 



Section I. Spikelets somewhat flattened, the glumes rather distant, 

 loosely imbricate, overlapping the rachis at the base so as not to leave a longi- 

 tudinal furrow, usually very thin with the lateral nerve on each side faint or 

 marginal. 



Spikelets usually 3 or 4- flowered, pedicellate, in a spreading panicle. — 

 14.— E. tenella. 



Spikelets Unear, more than 6- flowered. 



Spikelets numerous, pale-coloured, sliining, shortly pedicellate and crowded 

 on the long branches of a narrow panicle. — 9. E. leptocarpa. 



Spikelets numerous, very narrow linear, shortly pedicellate and distant 

 along the capUlary erect branches of the panicle. — 10. E. pilosa. 



Section II. — Spikelets when mature very flat. Glumes closely imbricate 

 in two distinct rows, leaving a longitudinal furrow or depression between them 

 on each side of the spikelet, the lateral nerve usually prominent in the middle of 

 each side of the glume. 



Base of the stems glabrous, not at all or scarcely thickened. 



Spikelets narrow, about 3 hnes long, crowded secund and spreading 

 or re flexed on the short clustered branches of a simple panicle. 

 Glumes very acute. — 11. E. Schultzii. 

 Spikelets under 3 hnes, sessUe in small dense globular or oblong 

 clustes sessile along a simple rachis. Stamens usually 2. — 4. 

 E. diandra. 

 Spikelets 3 to 6 hnes, rather narrow, usually sessile and erect, scattered 

 or clustered, rarely shortly pedicellate and spreading, in a simple 

 or branched panicle. Stamens usually 3. — 1. E. Brownii. 

 Spikelets 3 to 6 hnes long, broad sessile and crowded on a short, 

 almost simple, rachis. Palea-keels cihate with long rigid hairs. — 

 3. E. concinna. 

 Spikelets narrow, clustered along the long erect branches of a narrow 

 panicle. Palea narrow, truncate, glabrous, not above a third 

 as long as the glume. — 12. E. speciosa. 

 Base of the stem and short sheath of radical leaves thickened Into an ahnost 

 bulbous wooUy-hairy base. 



Spikelets shortly pedicellate, nearly 2 lines broad, the base of the 

 flowering glumes woolly-hairy. — 8. E. laniflora.
