228 FLOWERING PLANTS OF THE RIVIERA 



9. FESTUCE/E. Spikelets panicled or subspicate, terete, or laterally 

 compressed, 2 or more flowered ; rachilla usually produced beyond the flower- 

 glume, often bearing a rudimentary glume. Glumes 4 or more, 2 lowest empty,

10. HORDE/E. Spikelets i or more flowered, sessile in 2 opposite rows 

 on a simple rachis ; rachilla produced beyond the uppermost flower-glume (except 

 in Nardus). Flower-glume with a terminal awn or o. 



Sub-Tribe ELYME/E. Spikelets 2 or more in each notch, collateral ; the 

 central perfect ; the lateral perfect or reduced to bristles. Hordeum, Ely mus. 



Sub-Tribe TRITICE/E. Spikelets solitary in the notches, 3- or more 

 flowered. Aegilops, Triticum, Lolium, Brachypodium. 



Sub-Tribe LEPTURE/E. Spikes solitary in the notches, i-2-flowered. 

 Nardurus, Lepturus, Psilurus, Nardus. 



MI BORA Adans. 



Inflorescence a somewhat one-sided raceme. Glumes not keeled, blunt. 

 Flower r. Fertile glume scarious, very hairy, blunt, not awned. 



M. minima Desv. A very small, tufted annual, rarely 3 in. high. Stems 

 capillary, leaves short and narrow, with thin sheaths. Spikelets small, purplish, 

 almost sessile in a simple slender spike. Outer glumes obtuse, nearly equal. 

 Flowering glume shorter, very thin and scarious, hairy outside, jagged at top 

 but not awned. 



Sandy fields, here and there. February- April. 



ANTHOXANTHUM L. VERNAL GRASS. 



Barren glumes 4, the inner pair awned and enclosing i fertile glume and i 

 small pale. Stamens 2. Fertile glume broad, obtuse, and awnless. 



A. odoratum L. Sweet-scented Vernal Grass. Panicle spike-like, one- 

 sided at base, iJ-2 in. long. Outer glumes very pointed. Flowering glumes 

 usually included, or rarely the longest awn slightly protrudes. 



Grassy places, especially in hilly meadows. May-June. 



A. aristatum Boiss. The upper awn much exceeds the top of the spikelet, 

 and the fertile flower is not half as long as the sterile glumes. Annual or bi- 

 ennial. 



Crops and sandy fields near le Cannet du Luc (Var). May-July. 



PHALARIS L. 



Barren glumes boat-shaped, keeled, membranous, nearly equal, exceeding 

 the flower. Pale i-nerved, closely surrounding the fruit. Rudimentary flowers, 

 1-2, scale-like. Fertile glume broad. Keel often winged. Spikelets compressed. 



P. arundinacea L. Reed-like, 2-3 ft. high, with rather broad, long leaves, 

 densely tufted at the base. Spikelets numerous, in a spreading panicle 6-8 in. 

 long. Outer glumes lanceolate and pointed but not awned, keeled, but not 

 winged, pale green or whitish with green nerve. 



Ditches and watery places. June-July. 



P. Ccerulescens Desf. Panicle spike-like, cylindrical. Glumes acute. 

 Wing dentate, terminating abruptly. No barren floret. Pales thin, nearly 

 smooth. Roots beaded with 1-2 large tubers. Plant 2-3 ft. high. 



Dry meadows and borders of fields. April-June. 



P. nodosaL. Panicle spike-like, lanceolate. Glumes acute. Wing narrow, 

 entire. Neutral floret sublanceolate, villous as well as the pale. Roots formed 

 of 2-4 small tubers. Plant 2-3 ft. high. 



Damp places, road-sides, etc. May-June.
