208 PROCEEDINGS OF THE ACADEMY OF [1893. 



of plant life perform in more favored climes, and the amount of rich 

 vegetable matter being deposited by them may be of great value in 

 the future to that great arctic island. 



The Academy is indebted to Mr. Stewardson Brown, Correspond- 

 ing Secretary of its Botanical Section, for the determination of the 

 flowering plants ; to Dr. John W. Eckfeldt for the determination of 

 the lichens, while for the naming of the mosses the Academy is 

 indebted to the kindness of Mrs. N. L. Britton of New York, whose 

 knowledge of this department of botany is conceded to be pre-emi- 

 nent. 



Ranunculus Lapponicus L. 



Dr. Burk. 

 Ranunculus nivalis L. 



Etah, in great abundance, and with great vigor, a point char- 

 acteristic of the vegetation about this ancient Esquimo settlement. 



Ranunculus pygmaeus Wahl. 



Apparently confined to swampy places. 

 Papaver nudicaule L. 



Common everywhere in Greenland. A remarkably variable 

 plant. On the table land, back of McCormick Bay (Prudhoe Land) 

 a white flowered form is somewhat common ; it has a more compact 

 habit and smaller flowers than the yellow or more prevalent form. 

 On Wostenholm Island, the compactness of growth is particularly 

 marked. The number of petals varies, and the margins are not 

 unfrequently fimbriate. In the vicinity of Disco the peduncles are 

 hairy. At Upernavik forms with hairy and smooth peduncles grow 

 together. 



Cheiranthus pygmaeus Adams. 



Dr. Burk. 

 Arabis alpina L. 



Found only on Disco Island — only two specimens on soggy 

 ground, one in flower the other in fruit. 



Cardamine pratensis var. alpina L. 



Not in Dr. Burk's collections, and a single specimen only 

 gathered in wet ground on Disco Island. 



Vesicaria arctica Rich. 



Inglefield Gulf in dry places between rocks, in fruit middle of 



August.
