cells enlarged and formed gametes. The female were laterally hieiliate and measured about 

 1.5-2;* by 3-3.5^. The male were motile but the cilia were not observed. They measure 

 about 1 by 1.5/1. Actual fusion was not observed nor was the fate of the oospore determined. 

 Circumstantial evidence is offered to support the presumption thai they and not the carpo- 

 spores are the spores found on the rocks in October and which give rise to the ordinary fronds 

 of the plant. Further particulars are promised in a second paper. — Leonas L. Burlingame.

 do Brazil. [Ninth list of Brazilian diatoms.] Brotcria Ser. Bot. 17: .5-10. 1919. — The article 

 continues a series begun in 1913. Forty-one species and six varieties, none new, are listed 

 without description, but with copious references to literature and brief citation-; of localities.

MORPHOLOGY AND TAXONOMY OF BRYOPHYTES 



Alexander W. Evans, Editor 



2466. Andrews, A. LeRoy. [Rev. of: Hesselbo, Aug. The Bryophyta of Iceland. In: 

 Rosenvinge, L. K., and Eug. W arming. The botany of Iceland 1: 39.5-677. 39 fig. 1918. 

 (See Bot. Absts. 1, Entries 470, 1040, 1048.)] Bryologist 22: 4-5. 1919.— The reviewer points 

 out the care with which the author worked, but notes the lack of an adequate discussion of 

 the relation between the flora and the geologic substrata, and corrects certain erroneous state- 

 ments in distribution. — Edward B. Chamberlain. 



2467. Andrews, A. LeRoy. Notes on North American Sphagnum — VIII. Bryologist 22: 

 45-49. 1919. — The author continues from the seventh number of this series (Bryologist 20: 

 84-89. 1917) an account of the characters, ranges and specific value of the species of the gToup 

 Cuspidata. The following are among the conclusions reached: S. tenellum Pers. (not 

 [Schimp.] Klinggr.) is the correct name for S. mollusucum Bruch; S. cuspidatum Ehrh., is 

 closely related to, but not a form of, S. recurvum (Beauv.) Russ. and Warnst, and many arti- 

 ficial species belong here; S. cuspidatum var. Torreyi (Sull.) Braithw., is connected with the 

 typical form of the species by too many forms to rank as more than a variety; S. cuspidatum 

 var. serrulatum Schlieph., is an aquatic variant of more than formal value. At the close 

 of the paper the author notes the occurrence of S. Aongstroemii Hartm. at Cape Nome, Alaska, 

 the second record for the American mainland. — Edicard B. Chamberlain. 



2468. Evans, Alexander W. Notes on North American hepaticae — VIII. Bryologist 

 22 : 54-73. 2 pi., 15 fig. 1919. — Author discusses in detail and figures N ardia fossombronioides 

 (Aust.) Lindb., N. subelliptica Lindb., and N. rubra (Gottsche) Evans, comb, nov., this spe- 

 cies including Pacific Coast material previously called N. crenalata (Sm.) Lindb.; he gives 

 briefer discussions of Corsinia coriandrina (Spreng.) Lindb., Petalophyllum Ralfsii (Wils.) 

 Nees & Gottsche, and Leptocolea cardiocarpa (Mont.) Evans, all new to the United States 

 flora; he corrects previous reports for Sauteria alipina Nees from the Gaspe Pensinula (referred 

 to Clevea hyalina by error), notes that Alaskan material referred to Grimaldia fragrans is 

 really G. pilosa (Hornem.) Lindb., that Plagiochasma Mvenchianum Steph. is a synonym of 

 P. crenulatum Gottsche, and that Porella Cordaeana (Hueben.) Evans, comb, nov., is the 

 correct name for P. rivularis (Nees) Trevis. Two short lists of recently reported additions 

 to the hepatic flora of Florida and Alaska, respectively, are included in the paper. — Edicard 

 B. Chamb'rlain. 



2469. Burnham, Stewart II. Hepaticae of the Lake George flora. Bryologist 22: 33- 

 37. 1919.— This is an annotated list of 64 species from the vicinity of Lake George, New York. 

 Previous records and collections have been reviewed — Edicard B. Chamberlain. 



2470. Chamberlain, Edward B. Anacamptodon splachnoides var. Tayloriae in Missouri. 

 Bryologist 22: 16. 1919. — The range of the variety is extended from Georgia to Missouri. — 

 Edward B. Chamberlain.
