from the Island of Kauai, an island particularly rich in endemic 

 species and varieties, have added greatly to the herbaria of Hille- 

 brand, the Bishop Museum, and other institutions, and have 

 been worked upon by various specialists. Lydgate has been 

 responsible for the finding of a considerable number of new 

 species and varieties, and his name is perpetuated in a number 

 of plant names. 



Edivard Bailey. 



In 1883 Edward Bailey published a small manual "Hawaiian 

 Ferns, a Synopsis." 



Mr. Valdemar Knudsen, of Kauai, Mr. D. D. Baldwin, of 

 Maui, and the Rev. Edward Bishop, were all enthusiastic ama- 

 teurs whose collections have been of no small value in taxonomic 

 studies of the Hawaiian flora. 



29. Explorations by Heller. 



In 1896 A. A. Heller, of the University of Minnesota, and his 

 wife, visited the islands. He made numerous expeditions into 

 the leeward forests of Oahu and Kauai. He did not visit the 

 other islands. Heller published a very comprehensive list of his 

 findings, with many new species and varieties, as Bulletin No. 9 

 (1897) of the Minnesota Botanical Studies, (pp. 760-922, with 

 plates and maps). His work on Kauai took him into a rich and 

 diversified region, and he made many additions and corrections 

 to the work of Hillebrand. He also made some collections of 

 the marine flora. Heller's collections were deposited in the herb- 

 arium of the University of Minnesota. 



30. SCHAUINSLAND ON LaYSAN. 



In 1896-97, H. Schauinsland, of Germany, spent three months 

 on the Island of Laysan, and made extensive collections of the 

 fauna and flora. He collected marine algae here, also plankton 

 between Honolulu and Laysan, in the vicinity of Honolulu, and 

 at Pearl Harbor. His book, "Drei Monate auf einer Korallen 

 Inseln" (Bremen, 1899), described in detail the results of his 

 visit to the archipelago. His collections of algae were worked 

 up by Lemmermann. 



31. Visit of Miss Josephine Tilden. 



In 1900 Miss Tilden, of the University of Minnesota, with her 

 mother and Miss Crosby, made a visit to the islands for the pur- 

 pose of collecting algae. They collected on Oahu and on the other 

 larger islands, (Kauai, Maui and Hawaii). An account of her 

 visit and work is given in "Postelsia," the yearbook of the Min- 

 nesota Seaside Station, for 1901. She published a list of one
