Alsia Macouitii Kindb. Bull. Torrey Club 17 : 275. 1890. 



Plants seldom more than 3-4 inches high, more circinate when 

 dry than D, abiethia : leaves shorter, i mm., and broader, 0.5 

 mm., ovate-lanceolate, less serrate and acuminate at apex, papil- 

 lose only above the middle, papillae smaller and more numerous ; 



i 



base broader with strongly revolute margins, vein stouter and 

 less spinosely toothed at apex : capsules shorter and broader, with 

 a shorter seta more completely immersed in the broader and less 

 pointed, perichaetial leaves ; peristome longer and more slender, 

 less papillose ; endostome perforate ; spores larger and rougher. 



According to Kindberg, the only American species of Alsia is 

 A. longipes Sull. & Lesq., with which he associates a European 

 species of Eiirhy nchhi m ^ E. circinnatiun (Brid.) Br. & Sch. This 

 is another case of incomprehensible confusion, for apparently, there 

 is no resemblance, either superficial or real between these two 

 species. 



Alsia longipes has the leaf-characters of Dntdroalsia, but differs 

 in its sporophyte in several ways, having a long-exserted seta, a 

 cylindric capsule and an endostome with appendiculate cilia. Still 

 there seems no necessity for separating it from the other allied 

 species, so the following name is proposed : 



Dendroalsia longipes (Sull. & Lesq.). 



Alsia longipes Sull. & Lesq. Muse. Bor.-Am. Ed. 2. No. jpp. 

 1865. Sull. Icon, Muse. Supp. 85. //. 6j, 1874. 



Type station : On shaded rocks in deep canyons, Oakland, 

 California, Bolander. This species must be rare, as it is recorded 

 from only two other stations in California, viz,, near Berkeley, 

 M, A, Howe, and southern California, McClatchie, and one In 

 Alaska. 



Macoumella Kindberg. 



It is with much regret that I am forced to believe that the 



liclla Kindb. will not stand. As has already been
