This list is based on collections made by the author in 1897. The determi- 

 nations are largely by Dr. V. F. Brotherus, of Helsingfors, Finland. 



The author has excluded species collected by him and reported by previous 

 moss students, especially by Professor Max Fleischer, whose comprehensive work, 

 die Musci der Flora von Buitenzorg, appeared in 1902-1908. 



In its taxonomy the list follows Dr. Brotherus' treatment in Engler and 

 Prantl's Pflanzenfamilien.

MISCELLANEOUS NOTES 



Mosses and lichens exhibited at Chicago. — The exhibition of nature study 

 material held by the Wild Flower Preservation Society of Chicago, from January 

 6th to 22nd, 1920, proved a valuable object lesson to the general public and es- 

 pecially to the school children. Besides the mounted material, there were many 

 drawings in black and white and in color, and many photographs. The exhibit 

 of mosses and lichens attracted more attention than any other thing. Many 

 visitors whose botanical learning did not take them beyond the common flower- 

 ing plants, became interested in the new and strange beauty of the cladonias and 

 the feather mosses. There were fifty-six luxuriant specimens of mosses and 

 lichens exhibited, mounted upon stiff cardboards. As often as possible during 

 the course of the exhibit, these specimens were sprayed with water by means of 

 a fine atomizer, so that the little garden kept as green and lovely as if in a summer 

 rain. 



Many inquiries were made concerning books and named specimens, and 

 several small collections have been distributed by the writer, who recommended 

 to all the books by Dr. Grout, Mrs. Dunham, and Miss Marshall. The exhibit 

 was transferred from Chicago to Peoria, and will later visit others of the middle 

 western cities.
