In pools and muddy pond-holes, not common : Wauwinet ; 

 near Reed Pond ; near Tristram Coffin's homestead ; roadside 

 pool west of Maxcy's Pond. At the latter station it was freshly 

 in flower September 14, 1907, apparently a second growth, since 

 wherever found elsewhere it had long passed the flowering stage. 



Panicularia acutiflora (Torr.) Kuntze. 



Cato's Pond, 1899, and again 1907; this pond although 

 named on the maps was merely a pool in a low field sometimes 

 nearly dry in summer ; roadside pool near 'Sconset ; recorded from 

 Pout Ponds. In full flower. 



Puccinellia fasciculata (Torr.) comb. nov. 



I Poa fasciculata Torr. Fl. U. S. 1 : 107. 1824. 



f Frequent, about the borders of salt marshes. This is the 



common coastwise Puccinellia which replaces the larger-flowered 

 P. maritima (Huds.) Pari., from southern New England to New 

 Jersey. It has commonly been referred to P. distans (L.) Pari., a 

 very different plant and doubtless an introduced species in our 

 flora. True P. distans is decumbent at the base and has open 

 panicles, sometimes nearly half the length of the slender culms, 

 formed of almost capillary widely spreading or deflexed branches 

 sometimes 12 cm. long, in clusters of 2-5 and floriferous mostly 

 above the middle ; the spikelets are not crowded and are often slen- 

 der-pedicelled, the flowering scales 1.5-2 mm. long, truncate- 

 obtuse and rather distinctly nerved, the nerves below evidently 

 pubescent. 



In P. fasciculata, the culms, although often geniculate below, 

 are not decumbent but stiffly ascending or erect, the exserted part 

 longer than in P. distans and sensibly stouter and stiffer, the pan- 

 icles much smaller and narrower, sometimes almost spike-like, 

 formed of appressed or ascending stiff branches mostly single or 

 in pairs and floriferous from near the base, the spikelets crowded, 

 sessile or stipitate, the flowering scales 2-2.5 mm. long, acutish 

 or obtuse, more coriaceous than in P. distans and less distinctly 

 nerved, the base of the nerves glabrous or glabrate. 



Festuca octoflora Walt. 



'Sconset, along the top of the low bluff south of the settle-
