favose seeds. The calyx characters on which the genus is 

 largely based appear to be very unstable ones. 



Digitalis purpurea, Linn. Naturalized and apparently 

 perfectly at home about Eureka. 



Lysichihun Camtschatcetise, Schott. This is one of the 

 most striking plants of our western flora. It attains its best 

 development in the shaded swamps near the coast, where its 

 leaves often attain a length of four feet and a breadth of fif- 

 teen inches. Fine specimens with their velvety, slightly- 

 mottled, leaves would compare favorably with the Dieffen- 

 bachia products of our greenhouses. [This appears to be 

 the correct spelling of the name "Lysichiton Kamtschat- 

 censis " of the State Survey Botany and other works. — J.

 tical and it is also placed by Bornet and Flahault (Revision 

 (frag.) I; 370) under the list of ''Species Inqfiirendce.'^ 

 Several years before his death, Mr. Wolle sent to the writer 

 some of the original Hosford collection, but even traces of any 

 Calothrix were lacking. Dr. Smith Ely Jelyffe of Brooklyn, 

 N. Y., however, kindly sent to the writer some material col- 

 lected by him upon submerged stones in Lake George, N. Y., 

 in October, 1892, which Mr. Wolle had pronouuced to be his 

 Calothrix Hosfordii. The writer could not, at the time of 

 the receipt of the material, distinguish it from Dichothrix 

 Baneriana (Grun.) B. & F. Later, however, as he became 

 better acquainted with the American species of Dichothrix, 

 it seemed best to submit this specimen to Dr. Bornet, who 

 recognized its distinctness from D. Baueriana, but still
