species of lower levels near the lake-shores, where the flora is generally 
decidedly southern in aspect. 
The second species here proposed is a small plant of boggy habitats 
which is abundantly distinct from the species to which it has hereto- 
fore been referred. This plant we propose as 
Poa paludigena, n. sp., subcaespitosa vel vix caespitosa; culmis 
tenuibus 1.5-7 dm. altis laevibus vel superne minute scabris basi 
purpurascentibus, nodis 3-5; foliis angustis 0.25-2(-3) mm. latis 
laminis superioribus quam vaginis brevioribus vel rare eis aequalibus; 
ligulis brevibus truncatis superioribus 0.7-1.5 mm. longis; paniculis 
0.3-1.3 cm. longis nec secundis valde laxis disjunctisque, ramis 
elongatis tenuibus vix flexuosis patentibus rare reflexis glabris vel 
minute Rovers imis mediisque plerumque binis rarissime ternis ad 
apicem floriferis; spiculis 3-6 mm. longis 2-5-floris; glumis quam 
lemma proximum dimidio vel saltim quartam partem brevioribus; 
lemmatibus 2.5-3.5 mm. longis basi vix arachnoideis acutis vel acutius- 
culis apice scariosis plerumque purpurascentibus, nervis mediis 
marginalibusque pilosis plerumque infra medium, nerviis intermediis 
glabris obscuris; antheris 0.5-0.8 (rare —1) mm. longis. 
Culms slender, 1.5-7 dm. high, subsolitary or in small tufts, smooth 
or minutely scabrous at summit, purplish at the base, without elon- 
gated root-stocks; cauline nodes 3-5: leaves narrow, 0.25-2 (rarely 
-3) mm. wide; blade of the upper shorter than or rarely equalling 
the sheath; ligules short, truncate, those of the upper leaves 0.7-1.5 
mm. long: panicle 0.3-1.3 dm. long, not secund, very loose and open; 
branches long and slender, scarcely flexuous, widely spreading, rarely 
reflexed, glabrous or minutely scabrous, the lower and median chiefly 
in 2’s, very rarely in 3’s, spikelet-bearing above the middle: spikelets 
3-6 mm. long, 2-5-flowered: glumes one-half to three-fourths the 
length of the nearest lemma: lemmas 2.5-3.5 mm. long, scarcely 
webbed at base, acute or acutish; the tip scarious-margined and often 
purple-tinged; midrib and marginal nerves pilose chiefly below the 
middle; the intermediate nerves glabrous and obscure: anthers very 
small, 0.5-0.8 (rarely —1) mm. long.— In bogs or boggy places, central

Related to P. autumnalis Muhl. and P. reflexa Vasey & Scribner. 
From the former it differs in the bog habitat, finer and less caespitose
