HEPATIC^ COLLECTED IN ALASKA 297 



toward perianth, similar to the leaves but broader, irregularly lobed 

 or simply crispate-sinuate on the margins; innermost bracteole large, 

 irregularly bilobed or trilobed, the lobes mostly rounded, second 

 bracteole much smaller, other bracteoles indistinct ; perianth extend- 

 ing scarcely if at all beyond the bracts, delicate in texture, contracted 

 at the denticulate or subentire mouth ; archegonia about lo: antheridia 

 borne in the axils of the 9 bracts : capsule on a long and slender 

 stalk, spherical or slightly longer than broad ; spores very minutely ver- 

 ruculose. 



Leaves 0.7 x 0.9 mm., underleaves 70X 25 /a, leaf-cells in the middle 

 and at the edge of leaf 20 fx in diameter, at the base 33 x 23 />., 9 bracts 

 0.7 X 1.2 mm., spores 16, a in diameter. 



Disenchantment Bay (B. & C. 637^;, in part, 641, 641a, T. 1504) ; 

 Hidden Glacier Inlet (T. 1505, in part) ; St. Lawrence Island (T. 

 1517, C. & K. 2007, in part). New to Alaska. 



Nardia hcematosticta is apparently also new to the American conti- 

 nent, but has recently been reported from Greenland.^ It seems to be 

 much rarer in Europe than N. scalaris^ but has a wide distribution 

 there ih northern and mountainous regions. By many of the earlier 

 writers it was included under this latter species as a variety ; it is, 

 however, well distinguished by its smaller size, its less concave and 

 sometimes emarginate leaves, its paroicous inflorescence, and by the 

 early disappearance of its underleaves. These are. In fact, very diffi- 

 cult to demonstrate except in connection with the Inflorescence and in 

 very young apical regions, where the leaves are still undeveloped. 

 The curious ' fat-bodies,' so characteristic of N. scalaris^ are either 

 absent from the smaller species or are inconspicuous. The rudimen- 

 tary sac of N. hcematosticta is a most interesting feature and indi- 

 cates, as has already been pointed out by other writers, an approach to 

 such typically saccate genera as Arnellia and Gyrothyra. The species 

 has been well figured by Schlffner* and by Massalongo and Carestia.^ 



13. Nardia obovata (Nees) LIndb. 



Farragut Bay (T. 1464, in part); Kadiak (T. 1416, In part). 

 New to Alaska. 



The present species was first recorded for the United States by Dr. 

 Howe,* who based his determination upon sterile California specimens.
