476 SUMMARY OF CURRENT RESEARCHES RELATING TO 



J. M. Holzinger* gives an account of a botanical exploring trip (in 

 1902) on the north shore of Lake Superior in Minnesota, with an 

 enumeration of the mosses collected — namely, 2:51 species, varieties and 

 forms, many (145) of which are new records for Minnesota. He 

 appends some critical notes by Mons. Theriot on Hyptium uncinaturr* 

 and its forms in North Minnesota. 



R. S. Williams f having had to examine carefully several thousands 

 of moss-specimens, protests strongly against the poor quality of the great 

 majority of the specimens, and implores collectors to search for and 

 gather only the best possible examples of such species as they find ; it 

 is seldom that the fruit of the various species of Dicranum and Dicrano- 

 weisia is in a perfectly satisfactory condition in herbarium-specimens. 



T. C. Frye % gives an account and figures of Grimmia olympica E. G. 

 Britton, a new species collected by him high up in the Olympic Moun- 

 tains of Washington, a locality little known to botanists. 



J. L. Sheldon § publishes a list of twenty Connecticut hepaticaa from 

 localities additional to those recorded in the catalogue published by 

 Evans and Nichols. In a second list he gives nineteen hepaticse from 

 West Virginia, which are additional to those recorded in his previous 

 report of 1907. 



Mexican Mosses. |j — J. Cardot publishes a fifth article on Pringle's 

 Mexican mosses, giving preliminary diagnoses of twenty new species 

 and six, new varieties, with critical notes. 



Hepaticse of Madeira. 1 — E. Armitage publishes a list of hepaticse 

 gathered in Madeira in the first quarter of 1909, and determined by 

 S. M. Macvicar. The fist contains thirty-seven species and varieties, 

 fourteen of which are additions to the flora of the island. Previous lists 

 have been published by Mitten, Schiffner, and Luisier. 



East African Mosses.** — L. Cufino gives a list of Cryptogams col- 

 lected by F. Gallina in the Italian colony of Erythraea, and among them 

 the moss Pleurochsete malacophi/lla Broth. 



Charles Reid Barnes (1858-1910).f|- — Charles Reid Barnes is the sub- 

 ject of an anonymous obituary notice. For twenty-eight years a botanical 

 professor — namely, at Purdue, Wisconsin and Chicago Universities — he 

 was also well known as joint editor of the Botanical Gazette, in which 

 his reviews were trenchant but just. His published works treat of 

 laboratory work, plant Ufe, physiology, morphology, keys for the deter- 

 mination of the North American mosses. As a teacher of botany he 

 was unusually successful. 



M. A. Howe Xt also writes a notice of the above, and makes reference 

 to his Analytic Keys to the Genera and Species of North American 

 Mosses and other works.
