Mtisci Tschuctschici (auct. C. Miiller) is a paper which appeared in 

 three parts as follows : 



Bot. Centralbl. 16: 57-65. (1883). 



16: 91-95. (1883). 



16: 121-127. (1883). 

 A good many new species are described. The collection reported on in 

 this paper was made under the auspices of the Bremen Natural History- 

 Society, by which the two brothers, Dr. Arthur Krause and Dr. Aurel 

 Krause, were commissioned to make a journey of discovery to the Tschukt- 

 sches Peninsula (also spelled Chukches Peninsula). Accordingly these two 

 explorers spent the summer of i88r in the vicinity of St. Lawrence Bay, 

 Emma Harbor, and Liitke Harbor, collecting both geological and botanical 

 data and materials. The mosses of this expedition were entrusted for elab- 

 oration to Dr. Carl Miiller of Halle, whose report on them appears under the 

 above title." 



The pocket containing the plants sent by Dr. Engler bears with the 

 name the following data: "Peninsula Tschuctschica, St. Lorenz Bay, Geb. 

 A. & A. Krause. 12 Aug. 1881." 



Prof. J. B. Flett collected the plant in Alaska at two stations: first on the 

 tundra near Rodney, on July 13, 1900; second, on the tundra 16 miles west 

 of Nome City, on July 20, 1900. He kindly furnishes the following data: 

 "Nome is in latitude about 64^° N. and longitude 165^° W. It is about 12 

 miles N. W. of Cape Nome, Rodney river is a creek about 20 miles N. W. 

 of Nome City, along the coast." It thus appears that this Anierican station 

 is in nearly the same latitude as is the type locality, separated only by Ber- 

 ing Strait. But to Mr. R. S. Williams seems to belong the honor of being 

 the first to find this plant in North America, if the plant collected by him on 

 the Left Bank of Klondike below Bonanza Creek, on June 18, 1899." is 

 rightly referred here. The plants kindly communicated from the National 

 Herbarium by Mr. W. R. Maxon are sterile, with leaves entire, but of differ- 

 ent shape than in either of the two species of Psilopilum. The rectangular 

 basal leaf cells bring it rather to Carl Miiller's species; but they are much 

 shorter. The lamellae also are much more scant. And it is not impossible 

 that Mr. Williams' plants may prove to be a third species of Psilopilum. But 

 this can not be established with certainty without more abundant and fruit- 

 ing material, which so far is lacking. Winona, Mimi.
