Bv J. Cardot and I. Thf.kiot. 



Phasilm rusi'iDATUM Schreb. var. Americanum Ren. & Card. 



Is very close to the variety piliferum in the long excurrent costa and 

 apex often colorless, but is distinguished from it by the shorter leaves, 

 which are more papillose above, and by the very short, erect seta. Variety 

 mitraeforme Limpr is like it in the papillose leaves, but differs from it in 

 the larger leaves, in the less excurrent costa, and in a mitriform calyptra. 



Wisconsin: Madison, on ground in pastures, clover fields, and fallow 

 ground (L. S. Chenev, 1S93. Ren. & Card., Musci Amer. sept, exsicc. 

 No. 267). Missouri: old fields near Emma (C. H. Demetrio. 1891). Illinois:— 



Microbryuni Floerkcamini var. Hfiirici Ken. & Card, in Bot. Gaz. 14: 

 91. 1S99, from Kansas, leg. Henry, seems to be also a stunted form of the 

 same moss. It has also the calyptra cuculate, a character which separates 

 it from Mycrobryum Flflerkeaniiin. 



All the specimens we have received from North America as Phascuiii 

 ciispidiituin belong to this var. Americanum. 

 Gymnostomim Curvirostre Hedw. var. commutatum Card. & Ther. 



(Hymenostylum commutatum Mitt., Musci. Ind. Or., p. 32. Weisia 



curvirostris var. commutata Dicks., Handb. Brit. Mosses, 212). New- 

 foundland (Rev. A. C. Waghorne). 



This variety has long, narrow leaves, and the cells of the areolation are 

 everywhere long and smooth. In the type, the upper areolotion is com- 

 posed of irregular cells, rectangular, quadrate, and triangular, with pap- 

 illae. 

 Gymnostomum curvirostre Hedw. var. scabrum Lindb., musci Scand. 22. 



This form shows contrary variations to the preceding ; the leaves are 

 smaller, the cells quadrate, papillose; besides, the stem and nerve are gen- 

 erally covered with high papillae. 



Missouri: Benton Co., on moist rocks along Indian Creek (C. H. De- 

 metrio, 1893). Minnesota: Lewiston cave (J. M. Holzinger, 1889). Bear 

 Creek (J. M. Holzinger, 1890). Wisconsin: Madison (L. S. Cheney, 1892. 

 Ren. & Card. Musci Am. sept, exsicc. No. 269). 

 DiCRANUM viRiDE B. & S. var. laeve Ren. & Card. 



Distinguished from the typical form by its much laxer habit and less 

 crowded leaves, which are smooth at the back. 



Newfoundland: Bay of Islands, old stump (Rev. A. C. Waghorne, 1895). 



DiCRANUM ANGUSTUM Lindb., Soc. pro Fauna et Fl. Fenn., 1880, et Rev. 



Bryol, 9; 83. 1882, Lindb. & Arn., Muse. As. Bor. 2: 80 (description 



very complete). 



Northwest shore of Hudson Bay, lat. N. 63-65, long. 0.90.20 (G. Comes, 

 1893-1S94). We found some stems of this rare species amongst specimens 

 of Au/acoinniuni turgidittn.
