Brief Notes on the Distribution of Hepaticae

Abstract

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 tew plants were found in a specimen of Preissia quadrata collected at Apostle 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 observed. 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 during 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 material 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.
