Bicknell : Ferns and flowering plants of Nantucket 193 



which approaches typical examples of the species, the leaves 

 becoming 2-3 mm. wide, panicles 2-3.5 dm. * n length, and spike- 

 lets 3-3.5 mm. long. 



This species develops slender underground rootstocks, and the 

 culms are often branched from near the base, characters which I 

 have not observed in the tufted, green-panicled woodland grass, A. 

 perennans (Walt.) Tuckerm. (A. intermedia Scribn.), to which A. 

 elata has been referred as a variety. 



Holcus lanatus L. 



Scattered all over the island ; inflorescence mostly dried. 



AlRA CARYOPHYLLEA L. 



Widely scattered over the island and locally very common : 

 below the " Cliff/' east and west of the town ; on and below the 

 bluff at 'Sconset ; sandy levels about some of the ponds on the 

 south shore. Plants dead and dried but holding many spikelets 

 in the silvery panicles. 



Deschampsia flexuosa (L.) Trin. 



Very common over the moorland and dry commons and 

 abundant in the cedar barrens on Coskaty ; panicles dried. 



Danthonia spicata (L.) Beauv. 



Very common ; culms and spikes mostly dried. Among 

 scrub pines south of the county fair grounds, a stout, strongly 

 tufted form was collected September 2, 1904, bearing many fresh 

 panicles. This plant appears somewhat intermediate between D. 

 spicata and D. scricea Nutt, the sheaths and leaves being some- 

 what villous and the flowering scale rather densely pilose and 

 with slender teeth 2-3 mm. long. It seems to be precisely the 

 grass described from Long Island by Austin in 1872, as Danthonia 



Alleni. (Bull. Torrey Club 3 : 21.) 



It is frequent on Long Island and I have collected a variation 

 of it on Mt. Desert, Maine, and on Cobble Hill, Lake Placid 

 (apparently D. Faxoni Austin, Bull. Torrey Club 6 : 1 90. 1 877). 

 The Lake Placid specimens bore perfectly fresh panicles as late 

 in the season as October 20, 1901, although the first heavy snow 



had fallen two days before. 



Compared with D. spicata in its simplest state this stouter 

 form appears very distinct but intermediate examples everywhere
