earliest botanical field, about four miles from this place.*'

Descriptive Catalogue of the North American Hepaiicce North of -Mex- 
ico. By Lucien M. Underwood, Ph. D. Bull III State Lab. 
Nat. Hist., Vol. ii. 
The appearance of a work on the Hepaticai so soon after the 
publication of the Manual of N. A. Mosses will give students of the 
Bryophytes great assistance, and, with the author, we hope " that it 
may serve as a stimulus to more work in this direction, and lay in 
store material for a more critical examination of this group in the 
future." "No attempt has been made to publish new species, the 
writer believing that too many have already been described from in- 
sufficient data, and considering it far more necessary to set in order 
those already published.*' The catalogue therefore incorporates all 
of the work of C. F. Austin so far as accessible, Watson's MS. of 
Californian Hepatic^ and valuable information gained from Dr. 
Bolander, Prof, Forbes and others. There is a brief introduction on 
the characters, classification and bibliography, and three appendices 
on the geographical distribution, Lindberghs classification, and 
Dumortier's. The descriptions are very good, as is also the plan of 
giving references to descriptions and plates in other works, though a 
complete synonymy for each species would have been of great value. 
We note the omission throughout of the last n \\\ Juttgermannia. The 
author concludes as follows: "It is hoped that persons receiving this 
work will aid in further critical study of this group by communicating 
specimens of all forms found in their own localities."— E. G. Knight. 
Check- List of North American Gamopetal(B^ 8vo, pamph., pp. 43, 
. Under this title, Mr. H. N. Patterson, of Oquawka, 111., has pub- 
lushed, in convenient form for reference, a list of all the systematic 
i^ames given in Dr. Gray's recently issued Synoptical Flora. It will 
prove of value not only as a check-list, but also as a record of the 
changes that have been introduced into botanical nomenclature, for 
consultation by those who do not possess Dr. Gray's work. 
Select Extra- Tropical Plants readily eligible for industrial Culture or 
Naturalization, with Indications of their Native Countries and 
some of their Uses, By Baron Ferd. Von Mueller, K.C.M.G. 
8vo., pp. 450. Detroit: George S. Davis. 1884. 
This is a work which has already appeared in Victoria, New South 
^ales, India, and several European countries, and which is now 
Revised and still further augmented, for the especial use of North 
American readers. Its ol)ject is to bring together in condensed form, 
^^d in popular languages, data concerning the characteristics and 
^^onomic uses of all the principal plants, herbaceous and arboreal, 
^»at have been found to prosper in extra-tropical countries, and to 
point out the particular sections to which they are adapted.
