NOTES ON RADULA TENAX LINDB. 
Annie Lorenz. 
As the species under consideration has not heretofore been figured, some 
drawings and notes.on the subject may be of interest. 
The writer has found R. tenax at two stations at Water-ville, New 
Hampshire: in both cases it was upon grantite and at an altitude of 1800 ft. 
At the Cascades, the plants grew on the southern and western faces of the 
rocks, while at Greeley Pond they had chiefly a northern exposure. 
Radula tenax prefers the vertical faces of the rocks, and a moist atmos- 
phere, but not wet rocks. All the descriptions consulted give its habitat as 
old logs, but all the Waterville specimens were on rocks. It has the general 
appearance of Lej eunea cavifo lia (Ehrh.) Lindb. and is bronze green in color. 
Leaves with minute trigones. The perianth is unknown. Its New England 
distribution, as hitherto reported, is — N. H., Mass., Conn. 
The following description is taken from Underwood, Descriptive Cata- 
logue of N. Am. Hepaticae north of Mexico. Bull, of 111. State Lab. of Nat. 
Hist. Vol. II. Art. 1 (1883). 
• Radula tenax Lindb. Hep. Hibern, p, 492. 1875. 
“Dioecious: stems brownish -green, rigid, tenacious; leaves remote, 
scarcely decurrent, obliquely elliptic-ovate, opaque, the cells rounded and 
strongly chlorophylliferous, the posterior lobe rotund-ovate, scarcely half the 
breadth of the stem, the interior margin free, rotund, equal to the width of 
the stem or more, the apex plane or scarcely incurved: male spike borne on 
the side of the stem below the carina of the leaf, long-linear, somewhat 
obtuse. 
On rotten trunks, Md. N. C. Catskills, mostly in mountain regions.

BOOK REVIEW. 
Mosses and Lichens. By Nina L. Marshall, profusely illustrated in color, 
half-tones and line. 8vo. New York. Doubleday, Page & Co. $4.00. 
The introductory chapters are well written and are interesting and gen- 
erally accurate. 
, The drawings are many of them decidedly poor and some have a famil- 
iar look, though there are no acknowledgments. 
I will defy anybody however familiar with the mosses to put the right 
labels on the greater proportion of the colored plates and other photographs 
without seeing them previously labeled. Even the author has labeled as 
Climacium dendroides one of the colored figures which is not that species and 
is probably meant for Leucobryum to judge from the quotation below it. On 
page 55 the explanation of the action of the peristome of Poly trichum is 
decidedly original as I recall no such facts in literature or elsewhere. 
The arrangement of genera and species in the mosses is unlike that in 
any other work and has the merit of originality. I hope some day to have 
the plan explained to me.
