pairs, glabrous ; spikes broad, ovate, 3 9 flowered ; flowers 

 sometimes connected by woolly hairs, lower palere slightly 

 one-nerved, nerve densely pubescent on back. 

 Hab — Common in alpine localities. 



Var. a. lapponum, Laestad. — Root small. Leaves elongated,, 

 soft. Panicle lax ; spikes large, lower glumes subrotund, often 

 growing solitary ; colour variable, pale and obscure green or 

 purple violet and flavescent. 



Hab. — On rich soil in subalpine localities. 



Var. b. alpestris, Andersson. — Stems laxly ca?spitose, robust. 

 Leaves short, horizontally spreading. Panicle oval or oblong, 

 contracted ; spikelets largely ovate or broadly oblong ; often 

 viviparous. 



Hab.— On rocky places at great elevations. 



Var. c. australis, Andersson (P. alplna var. collina (Hort.) 

 Whg. ; P. badensis, Willd., Reich.; P. brevifolia, Waller & 

 Schech). — Stems slightly digitate, very eccspitose, base straight 

 and densely leafy. Leaves rigid, subglaucous. Panicle con- 

 densed, often small, oval or oblong ; spikes oval, of a beautifully 

 variegated violet-green, glumes long. 



Hab. — Dry subalpine localities. 



It will be observed that the plants now shown 

 agree perfectly with the vars. lapponum and alpestris. 

 I hope that some of us may be able, before the end 

 of this season, to compare var. australis with the 

 description given above, as I am sure it is to be 

 found growing on the south-western slopes of Ben 

 Laoigh.
