stributed (Herb. N. Y. Bot. Garden !) as well as an undescribed 

 species of Leptocladia (to be named L. conferla below) in one copy 

 (Ex Herb. Asa Gray in Crypt. Herb. Harvard Univ. !). It seems per- 

 fectly possible, then, that Andersoniella Farlowii may be found in 

 other regularly issued copies of this distribution. D.r Anderson also 

 distributed duplicates from his collection with the printed labels of 

 the Alg. Exs. Am. Bor., and this has been a source of confusion in 

 the case of certain numbers. 



The four slides in the Schmitz collection, prepared from no. 28 

 of the Alg. Exs. Am. Bor., represent the plant distributed under 

 no. 700 of the Phyc. Bor.-Am. mentioned âbove as being the Lepto- 

 cladia Binghamiae of J. G. Ag. They are not labellet Andersoniella 

 by Schmitz but « Farlowiella ». They agrée, however, with Schmitz's 

 description of his Andersoniella Farlowii and it seems extremely 

 probable that Schmitz finding Farlowiella preoccupied, changed the 

 name in his manuscript, without changing the désignation on his 

 slides. 



The name for the Californian plant must be Leptocladia Bingha- 

 miae J. Ag., and it seem as certain as may be made possible that 

 the later Andersoniella Farlowii Schmitz is the same plant. It is 

 not uncommon on the coast of Southern California (San Diego Mrs. 

 M. S. Snyderl, Will Wright!, H. Hemphill!, Miss Minnie Reed ! ; San 

 Pedro, A. J. Me Clatchiel, Mrs. S. C. Purdy, !, W. A. Setchell!: 

 Ventura, Mr. Tenneyl; Santa Barbara, Mrs. Bingham, Dr. and Mrs. 

 L. N. Dimmich!); and it extends up to Santa Crux [Dr. C. L. An- 

 derson!, Dr. W. G. Farlow /). Both cystocarpic and tetrasporic plants 

 hâve been found.
