572 THE FUR SEALS OP THE PRIBILOF ISLANDS. 



130. Luzula arcuata, Hook., var. unalaschkensis, Pr. Buch. 

 Exposed hilltops on both islands. 



131. Luzula confusa, Lindb., var. latifolia, Buch. 



With the last, but also on lower levels on both islands. 



132. Luzula campestris, Desv., var. multiflora, Celakovsky._, 



L. campestris, var. sudetica, Merriam's list. 



Same distribution as the last, but not quite so abundant. 



133. Potamogeton filiformis, Pers. 



In a shallow pond on St. Paul Island. 



134. Eriophorum polystachyon, L. 



In boggy places on St. Paul Island. 



135. Eriophorum vaginatum, L. 

 Bogs on St. George Island. 



136. Carex leiocarpa, C. A. Meyer. 



On boggy tundra on St. George Island. Not rare. On a grassy bank near a pond 

 on St. Paul Island. 



137. Carex pyrenaica, Meyer. 



Young plants of what I believe to be this specie's were found growing with the 

 last on St. Paul Island. My plants answer well enough to Meyer's description of 

 G. micropoda, which, according to Boott, is identical with 0. pyrenaica. Herb. No. 

 16611. 



138. Carex norvegica, Schk. 



Collected on St. Paul Island by Dr. Merriani. 



139. Carex lagopina, Wahl. 



Common on both islands. The var. gracilescens in bogs. 



140. Carex lagopina, Wahl., var. longisquama, Geo. Kakentlial. 



Spikes, 4 to 6, more elongate than in typical G. lagopina. Scales a little longer 

 than the perigynia, broadly hyaline on the margins. Mossy uplands, St. Paul Island. 

 Herb. Xo. 16620. 



141. Carex pribylovensis, J. M. Macoun. 



Culm, 30 to 40 cm. high; spikes, 3 to 4; ovate, roundish in a dense head; utiicu- 

 lus broadly ovate, very shortly beaked; scales broad and almost obtuse, a little 

 shorter than -the utriculi. Intermediate between G. lagopina and G. glareosa, to the 

 latter of which species this plant has been referred by Professor Bailey. Herb. No. 

 16609. 



142. Carex gmelini, Hook. 

 Common on both islands. 



143. Carex vulgaris, Fries. 



An almost typical form of this species is common on low flats where water lies 

 late in the spring. Specimens nearly approaching the var, turfosa, Fries (Herb. No. 

 16612), were collected in a marsh on St. Paul Island. These have been identified as 

 C. vulgaris var. hyperborea by Professor Bailey and C. limula by Mr. Kukenthal. The 

 rhizome strong; scales black; perigynium nerveless; and in these respects they agree
