BRIEF NOTES ON THE DISTRIBUTION OF HEPATICAE 



GEORGE H. CONKLIN 



I. LOPHOZIA Kaurini (Limpr.) Steph. 



Just before the issue of the March (1911) Bryologist containing 

 the excellent drawings of Lophozia Kaurini by Miss Lorenz, a few plants 

 were found in a specimen of Preissia quadrata collected at Aposde 

 Islands, Ashland Co., Wisconsin, in May, 1902, by Prof. C. E. Allen 

 of the University of Wisconsin. These plants were determined by 

 Dr. Evans as Lophozia Kaurini. 



A little later, in examining the material collected by the writer 

 Oct. 3, 1910, at Black River, near Superior, Douglas Co., Wisconsin, 

 good fruiting plants of this beautiful and rare species were again ob- 

 served. In this instance also, it grew associated with Preissia quadrata^ 

 on high wet rocks along the side wall of the stream half way up 

 the falls. The plants collected here as well as those from Apostle 

 Islands dry a dark brown, the leaf cells are large, with .arge trigones, 

 and the leaves show blunt lobes as in the specimens collected by 

 Miss Lorenz. The plants were fruiting and plainly paroicous and 

 the large fully developed barrel-shaped perianth, contracted into a 

 long beak and ciliated at the mouth, is a striking object even under a 

 simple lens. 



The leaf cells when dry have a glistening appearance not unlike 

 Calypogeia Trichomanis, except that the cell outlines are here dark and 

 brown, instead of yellowish white. A week later while examining 

 Prof. Allen's material from Isle Royale, Lake Superior, collected dur- 

 ing the summer of 1901, the writer again found the species, this time 

 mostly in a sterile condition. It would be interesting in view of the later 

 facts concerning Lophozia badensis, Lophozia Kaurini and Lophozia 

 Muelleri to examine all the Lophozia Muelleri mstevial in the various 

 herbaria. The writer would also suggest a close scrutiny of all the 

 Preissia quadrata specimens, as it is a very commonly associated species. 



Apostle Islands are about 75 miles east of Superior, Wis., on the 

 south shore ; Isle Royale is about 200 miles northeast on the north 

 shore of Lake Superior. These three localities make a third regional 

 station for Lophozia Kaurini for North America, the other two being 

 Yukon and Vermont- 



Two allies of Lophozia Kaurini, viz. — Lophozia Muelleri and Lophozia 

 heterocolpa (the Jungermannia Wattiania of Gray's Manual) — occur 

 in the Duluth-Superior district. Sterile forms of Lophozia Kaurini 

 might easily be mistaken for Lophozia heterocolpa, which is 

 very common along all the rocky waterways. The former, how- 

 ever, is a much larger plant. Lophozia heterocolpa occupies in size an 

 intermediate position between Lophozia Kaurini and the dioicous 

 Lophozia Muelleri. It has the same brown color when dry, but is more
