HELPFUL LITERATURE FOR STUDENTS OF NORTH 
AMERICAN HEPATICAE. 
Caroline Coventry Haynes. 
Having been asked to give a list of books and pamphlets that I find 
most useful in the study of hepatics, I have prepared the following. It may 
appear long but the fact of there being no up-to-date manual obliges one to 
consult many authorities in order to comprehend our North American flora. 
Among Dr. A. W. Evans’ publications are the following, bearing 
directly upon this flora: 
“A Revision of the North American Species of Frullania.” Trans. Conn. 
Acad. Vol. X. May, 1897. 
“The Lejeuneae of the United States and Canada.” Mem. Torrey 
Club, Vol. 8. No. 2, 1902. 
“Notes on the North American Species of Plagiochila.” Bot. Gaz. Vol. 
21. April, 1896. 
“ Odontoschisma Macounii and its North American Allies.” Bot. Gaz. 
Vol. 36. Nov. 1903. 
“A New Hepatic from the Eastern United States.” Bot. Gaz. Vol. 34. 
Nov. 1902. ( Diplophylleia apiculata Evans). 
“ Notes on New England Hepaticae” have appeared from time to time 
in Rhodora. Dates of publications as follows: Nov. 1902, Aug. 1904, Sept. 
1904, March, 1905, Feb. 1906, and March, 1907. These are critical notes. 
“List of New England Plants, — Hepaticae” apeared in Rhodora, 
June, 1903. 
“Studies Among our Common Hepaticae” came out in The Plant 
World as follows: Vol. 1. No. 7, April, 1898; Vol. 1. No. 9, June, 1898; Vol. 1. 
No. 12, Sept. 1898: Vol. II. No. 5, February, 1899. These deal with four 
species and are beautiful models of the correct way of taking up the study. 
The works of Dr. Marshall A. Howe on the Hepaticae are also of the 
first importance: 
“ Hepaticae and Anthocerotes of California.” Mem. Torrey Club, Vol. 
7, 1899. < 
“ North American Species of Porella.” Contributions -from the Depart. 
Bot. Col. Univ. No. 126, 1897. 
“ New American Hepaticae.” Bull. Torrey Club, Vol. 25, No. 4, April, 
1898. ( Scapania heterophylla and Riccia trichocarpa). 
“Notes on Californian Bryophytes ” appeared in Erythea, Vol. II. No. 
6, June, 1894. Vol. IV. No. 3, March, 1896. Vol. V. No. 8, Aug. 1897. 
Dr. Lucian M. Underwood’s poineer work is also of great interest and 
value : 
“Descriptive Catalogue of the North American Hepaticae, North of 
Mexico.” Bull. Illinois State Laboratory, Vol. II. 1884. Gives 231 species. 
“ Notes on our Hepaticae.” No. 1. Northern Species, Bot. Gaz. 14; 1889. 
No. 2. The Genus Riccia, Bot. Gaz. 19: 1894. No. 3. The Distribution of 
the North American Marchantiaceae, Bot. Gaz. 21: 1896. No. 4. The 
Genus Fossombronia, Bot. Gaz. 21: 1896.
