toward the base of the leaf ; cuticle smooth : $ bracts a little larger 

 and paler than the leaves but otherwise scarcely distinguishable from 

 them, lobes a little more acute, with entire or very obscurely angular- 

 dentate margins; bracteoles wanting ; perianth ovate-cylindrical, gradu- 

 ally contracted and deeply 4- to 5~plicate in the upper part, the mouth 

 lacerate with ciliate divisions, the cilia slender, variously curved and 

 contorted ; color of the perianth pale at the base, hyaline at the mouth, 

 reddish or brownish in a broad median zone; cells in a single layer 

 except at the very base, thick-walled, some of the cells in the upper 

 part projecting outward and upward as obtuse or subacute papillae, one 

 or two cells long; archegonia 10-12: $ spike intercalary, bracts in 

 6-1 o pairs, imbricated, smaller than the leaves and more delicate but 

 similar in shape, strongly concave, arching across axis and sometimes 

 bearing a small lanceolate or ovate lobe-like tooth at antical base ; 

 antheridia mostly in pairs ; paraphyses sometimes present, minute and 

 very variable in shape, from subulate to oblong and from acuminate to 

 obtuse at the apex : sporophyte unknown. 



Stem 0.2 mm. in diameter, leaves 0.9 x 0.8 mm., leaf -cells at edge 

 of leaf 14 fi. in diameter, in the middle 19 x 17 /*, at the base 35 x 17 M 

 9 bracts 1.05x0.95 mm., perianth 2.2x1 mm., $ bracts 0.7x0.75

The discovery of this local European species in America is a matter 

 of much interest, more particularly as the specimens are more complete 

 than any that have yet been described. The plant is known in Europe 

 from various parts of Austro-Hungary, from Italy, and from the 

 mountainous regions of southeastern Norway, where, according to 

 Kaalaas, it is not especially uncommon. 



It will be noticed that my description of the perichaetial bracts and 

 perianths does not agree in all respects with the published descriptions 

 of European authors. Upon consulting these descriptions, however, 

 it will be found that they are at variance with one another and that all 

 are drawn from specimens with undeveloped perianths. The earliest 

 account of the floral organs is that given by Limpricht, 1 and is as fol- 

 lows: bracts smaller and more tender [than the leaves], hollow, 

 sharply incised, sparingly toothed ; bracteole almost rectangular, many 

 times irregularly incised; perianth immersed, very tender, plicate, 

 deeply and irregularly laciniate-ciliate ; archegonia about 12, always 

 unfertilized. He states also that scattered cells of the perianth some-
