236 FLOWERING PLANTS OF THE RIVIERA 



K. valesiaca Gaud. Allied to the last, but with stem hairy at the top and 

 with glabrous spikelets. Glumes ciliate on keel. Pale acuminate. Lower 

 leaves convolute-setaceous. 



Dry hill-sides. April-June. 



K. cristata Pers. grows in dry slopes, and the loose panicled K. Michelli 

 COM. (like a Vulpia in habit) in dry sandy woods. 



QLYCERIA R. BY. 



Glumes unequal, sub-membranous. Fertile glumes with 5-7 strong prominent 

 ribs and a scarious margin, subcylindrical. Nut oblong, convex on back, fur- 

 rowed within, free. Spikelets many flowered. 



The following species occur, viz. : Q. convoluta Fries, Q. tenuifolia 

 Boiss. et Rent., Q. festucaeformis Heyn. (rare, near Toulon, Sanary, and 

 Hyeres), Q. distans Wahl., Q. fluitans R. Br., and Q. plicata Fries. 



CATABROSA P. Beauv. 



Glumes unequal, very short, i-veined. Fertile glumes cuneate and 3-toothed, 

 at tip, membranous. Upper glume often with 2 short and faint lateral veins. 



C. aquatica P. Beauv. Qlyceria aquatica Presl. This pale green, 

 tender aquatic grass is recorded from La Seyne near Toulon. The stems are 

 creeping or floating at the base, rooting at the nodes and often 2 or 3 ft. long, 

 the flowering branches are erect, the panicle pyramidal. May-July. 



POA L. 



Glumes rather unequal. Fertile glume 3-5 veined, scarious at the tip, com- 

 pressed, keeled. Nut elliptic trigonous, slightly furrowed within, free. The 

 following occur in our district : P. compressa L., P. pratensis L., P. Chaixii 

 Vill. (in mountain woods), P. trivialis L., P. nemoralis L. (in mountain 

 woods), P. bulbosa L. (very common), and P. annua L. 



ERAGROSTIS P. Beauv. 



Glumes much shorter than the spikelet. Inner and outer glumes similar, 

 membranous, with 3 prominent converging nerves. Panicle spreading. 



E. major Host. (E. megastachya Lk.). Panicle spreading, branches 

 solitary or in pairs ; lower hairy at base. Spikelets linear-oblong. Florets 

 15.35, obtuse, with a short point. Sheaths smooth. Seeds reticulate. Annual. 



Sandy cultivated ground. May-October. 



E. minor Host. (E. poteformis Lk.). Panicle spreading, more delicate 

 than the last, branches solitary or in pairs ; lower ones hairy at base. Spikelets 

 ovate-oblong. Florets 9-19. Sheaths hairy. Annual, about a foot high. 



Same places as the last but less common. May-October. 



E. pilosa P. Beauv. Panicle contracted when in flower. Branches semi- 

 verticillate ; lower hairy at base. Spikelets linear. Florets 5-13, acute. 

 Lateral nerves of outer pale rather indistinct. Sheaths smooth. Annual about 

 a foot high. 



Sandy, fields in the Var. June-October. 



MOLINIA Schrank. 



Glumes unequal, without lateral ribs, falling short of the lanceolate spikelet 

 of 2 or 3 semi-cylindrical flowers and a subulate rudiment. Pales 2-nerved, 

 obtuse. Fertile glumes 3-nerved, very strong. Spikelets in a slender panicle. 



M. caerulea Moench. Purple Molinia. Panicle rather contracted, often 

 purplish. Spikelets erect, awnless, about 3-flowered. Fertile glume 3-nerved, 

 acute, hairless. Stems nearly naked, erect, stiff. Plant 1-3 ft. high, glabrous. 



Damp heaths and grassy places. June-October. Very variable.
