dull in appearance. It is readily distinguished by its uprig-ht gemmi- 

 parous branches, rarely absent, bearing masses of gemmae on large- 

 celled, strangely modified, three ranked leaves. Lophozia heterocolpa 

 is also dioicous. although it fruits so rarely that out of hundreds of 

 collections of this plant carefully searched, only one perianth has been 

 found. Lophozia Kaurini and Lophozia Muelleri fruit freely in this district. 

 II. Lophozia Bauertana Schiffn. 



Dr. Evans has fully described this species in his Notes on New 

 England Hepaticae (Rhodora 10: 188. 1908). At that time the 

 species had been recorded from Arctic America (Greenland, EUes- 

 mere Land, and North Lincoln) by Bryhn, and from one New Eng- 

 land stadon, at Litde Saddleback Mountain, Franklin Co., Maine 

 (Chamberlain and Knowlton). Since then Dr. Evans has received 

 specimens from Cape Caribou, Bic, Rimouski Co., Quebec (J. F, 

 Collins, 526'5, Julv 22, 1907); Pipestone Creek, Atha, (J. Macoun, 

 57, June 30, 1904); Lake O'Hara, B. C. (J. Macoun, 4Z Aug. 

 10, 1904). 



Lately the plant has been sent to the society herbarium, from four 

 other localities so widely separated, that it is evident that the distri- 

 bution of the species is much more extensive than was formerly sup- 

 posed. The new stations are : — 



Sissoi, Cal. (George M. Pendleton); 



Glacier National Park. Montana (John M. Holzinger); 



Riguad, Quebec (Prof. H. Dupret); 



Glacier, B. C. (C. C. Kingman). 



The plants in each of these coUecdons show the distinguishing 

 marks of the species, which are as follows: — 



The plants are intermediate in size between Lophozia Floerkei and 

 L. lycopodioides; the underleaves are sparingly ciliated, the lobes of 

 the leaves are often four instead of three, and apiculate instead of 

 blunt as pertains to L. Floerkei. The lobes of the leaves often end in 

 a sharp bristle-like point, similar to those of L. lycopodioides, but the 

 leaves lack the size, breadth, fluted, crisped, and ciliated condition of 

 the leaves of that species. The plants of L. Baueriana are generally 

 freely gemmiparous, unlike most of the other species of the barbata 

 group ( Barbilophozia,) to which it belongs. L. aftenuata (MsiVt.) Du- 

 mort. is of course an exception, but bears its gemmae on upright 

 shoots of closely appressed modified leaves. It is of interest to 

 note that Dr. Karl Muller^'^ combines L. Baueriana Schiffn; Junger- 

 mamia Hafchen"Ev3ins, an Antartic species from Patagonia; Barbilo- 

 phozia Hatcheri (Loeske); and similar plants of other authority, 

 under the name of Lophozia Haicheri (Evans) Stephani. It is by this 

 name that the species will probably be known. It has a wide Euro- 

 pean distribution, and the collections reported here also show a 

 considerable range for North America.
