Studies in Sisyrlnchium— Y; Two new eastern Species 



By Eugkne r. BicKNKi.i. 



Up to the present time four species of Sisyrinchluut have been 

 recof^nizcd in the flora of the eastern coastwise states from New 



J 



■tifc 



est species of New York and New England and the only one rang- 

 ing far northward and eastward through Maine to the provinces ; 

 5. grauiiiioidcs, extending from east IMassachusetts far southward 

 and westward; 5. Atlaiiticuvi, abundant along the coast from Mas- 

 sachusetts southward and occasionally found inland, as at Stratton, 

 Vermont (A. J. Grout) and Concord, New Hampshire (W. W. 

 Eo-'deston), and 5. mucrouatuiii Michx., common in the Alleghany 

 re^^ion of east Pennsylvania and extending to central New York 

 but as yet not reported east of the Delaware River. 



To these four species two others must now be added, one a 

 coastwise plant of New York and New Jersey, the other occuring 

 from southern New Jersey southward. These new species are 



here described. 



m arenicola 



Closely caespitose in stiff erect tufts 20-40 cm. tall from short 

 woody rootstocks, the tufts coarsely brown-fibrous at base, the 

 fibrous roots numerous, long and slender, becoming nearly black : 

 stems and leaves rather bright green, sometimes glaucesceit, 

 readily discoloring to brown or black in drying, the spalhcs and 

 often the stems and leaves puri)lish-tinged : leaves usually over 

 half the height of the stem, stiff and erect, often slightly curved, 

 .5-3 mm. wide, cuspidate-attenuate, strongly closc-striate, minutely 

 ccllular-puncticulate between the nerves, the edges denticulate- 

 serrulate to smooth : stem erect but often forming a shallow 

 doublecurve, sometimes spirally twisted, 1-3 mm. wide, the distinct 

 wings firm, striate, denticulate- serrulate or smooth ; bracteal leaf 

 conspicuous, erect, continuing the line of the stem, often slightly 

 incurved, attenuate-acute, usually subequal with the peduncles, 

 the rather broad compressed base strongly striate and oppositely 

 bicarinate ; peduncles 2-4, subcrect or somewhat outcurved, in 

 their early development appearing lateral from the stem, approx'i- 

 mate or, when only two, the outer one often divergent, somewhat 

 unequal, very short or elongated, 3-12 cm. long, stiff, wing-mar-
