 on the western islands of the Aleutian Chain. Grows amongst the scanty grasses on the dryer hill- 

 tops. T.) 



L. alpinum, L., Unalashka. Found in abundance throughout the treeless districts of Alaska. 



L. dendroideum, Michx., Sitka ; fide Ledebour, Flora Eossica.

PILICES. 



Ophioglossum vulgatum, L., (obtained only at Unalashka, where it grows in great abundance 

 among the rankest patches of other ferns and weeds. The leaf is bright sap green during life, 

 and turns golden yellow as it withers. This species was carefully sought for among the other 

 islands, but not discovered. T.) 



Botrychium lunaria, L., Unalashka. (Abundant at Unalashka and Attu. Not observed else- 

 where, though carefully searched for. This fern grows on the edges of the rocks which have been 

 covered with a light or thin deposit of soil. The number of plants found at any given locality, 

 though of very restricted area, may be as great as fifty, and varying from 1 to 6 inches in height. 

 At Attu they were found on the gravelly level at the head of Chichagof Harbor, among the scanty 

 grasses just a few rods west of where are the remains of the former houses of the natives who were 

 taken to the Commander Islands. At Sarana Bay, on the northeast side of Attu, this fern grows 

 in great profusion and attains a height of 9 inches in the rich, warm, sandy soil which is at the 

 head of that bay, among the rank grasses of that place, near the present houses which constitute 

 the summer village of the Attu people. T.) 



(B. boreale, Milde. This species was not observed elsewhere than on the sides of the paths 

 beyond the graveyard at Iliuliuk village, Unalashka. It never grows in patches. Earely more 

 than one stalk will be found at a time or separated by at least a few inches from another, and not 

 more than half a dozen will be found near the first. It attains a variable size of half an inch to 

 4 inches in height, depending altogether on the, soil, for in those places where the banks, or sides 

 of the cow-paths have parted, and fresh soil has been exposed several years before will be found 

 the larger plants of this species. T.) 



(B. lanceolatum, Aug-st., Common at Unalashka, growing isolated among the scanty grasses 

 and mosses of the low hill-tops and along the broken edges of the paths leading beyond the lake 

 southeast of Iliuliuk village. T.)
