' 62 Rhodora [MAnCH 
done in this group by Maine botanists. I am indebted to Prof. L. 
S. Cheney of the Univ. of Wisconsin, for various determinations. 
The following five species were very abundant on wet soil about 
the iron deposit about a halí mile from the Iron Works, and were the 
only species noticed at this place. The large amount of iron in the 
soil being apparently very favorable for their development. 
Bryum caespiticium L. (no. 156). 
* Dicranella cerviculata Schimp. (no. 18). 
* Ditrichum vaginans (Sulliv.) Hampe. (no. 53). 
Pogonatum tenue ( Menzies) E. G. Britton (no. 180). 
Chiloscyphus polyanthos (L.) Corda. (no. 19). 
The remaining species listed below were mainly collected on Chair- 
back Mountain, which has an altitude of about 2,000 feet and is nearly 
six miles from the Iron Works. As it was necessary to make this trip 
and return to the Iron Works in time to get the afternoon train, very 
little time could be given to collecting, and therefore the following list 
does not fully represent this region. Among the more notable species 
are Amblystegium irriguum spinifolium Schimp. and Leskea nervosa 
Myrin., the former being very rare in America. 
* Amblystegium irriguum spinifolium Schimp. (no. 319). 
Andreea petrophila Ehrh. (no. 3). 
* 4nomodon attenuatus Hueben. (no. 267). 
Anomodon apiculatus Br. & Sch. (no. 267). 
Brachythecium campestre Br. & Sch. (no. 299). 
Brachythecium Nova-Anghe (Br. & Sch.) J. & S. 
Brachythecium oxycladon (Brid.) J. & S. 
* Brachythecium populeum (Hedw.) Br. & Sch. 
Brachythecium salebrosum (Hoffm.) Br. & Sch. 
Catharinea undulata (L.) Web. & Mohr. (no. 178).
