Brj'-ophyten. — Pteridoph3''ten. 667 



this species in New Zealand; but is able to record the indisputable 

 existence of an aquatic form of the species near Hunterville, north 

 of Marton, in the North Island, where it was found by C. J. 

 Burgess in 1905. It was also gathered b}^ J. Drummond on the 

 Swan River, West Australia. A. Gepp.

Two groups, each of two closely related species, are described, 

 with notes on their distribution. The first group comprises Fissidens 

 mcoiistajis Schimp. and F. synoicus Sulliv. These species are sjmo- 

 n3"mous in the Manual of Lesquereux and James, and only one 

 Station is given. F. inconstajis, however, was known to James from 

 Colorado specimens collected by Porter and has been found grow- 

 ing with F. synoicus in Illinois by the author. It was described 

 originally from English specimens and has been variouslj^ treated 

 by European botanists, being as a rule placed as a subspecies or 

 väriet}^ of F. incurvus. F. synoicus was described by Sullivant 

 from the Texas material cited in the Manual under F. inconstans. 

 The author finds the species to differ in the time of fruiting, and 

 in the inflorescence which is autoecious in F. inconstans but synoe- 

 cious or dioecious in the other species. Further, F. inconstans has 

 a deeply divided peristome, spiralh'- thickened teeth, a thickened 

 leaf-margin and j^ellow spores. F. sy^ioicus has a smooth , less divided , 

 unthickened peristome, a fainter margin and green spores. Figures, 

 detailed descriptions and comparisons of the two species are given. 

 . The second group contains F. exiguus Sulliv. and F. minutiiliis 

 Sulliv. These species have been greatly confused and have a varied 

 sjmonymy. They are distinct in the structure of the leaf-margin: 

 F. niinuttihis having linear, cordlike marginal cells; F. exiguus pos- 

 sessing merely a Single row of paler cells, as is shown in the 

 original plate. There are also minor differences in the shape of the 

 leaf and of the peristome. E. B. Chamberlain.

1. Lophozia atlantica (Kaal.) Schiffn. was found by the author 

 at Hebden Bridge in June 1904. It grows there in large patches 

 on blocks of Millstone Grit. The plant is of about the size of L. 

 gracilis; but that species is confined to limestone, and bears no 

 stipules. L. atlantica had only once been recorded previously for 

 Britain, namelv as gathered in Caithness in 1901 by Rev. D. 

 Linie; but the 'author now finds that is was collected by Mr. Wa- 

 terfall in Cumberland in 1886, and by Mr. Macvicar in Clyde 

 Isles in 1906. It is also found in Norway and the Faroe Isles. 



2. The author also points out the characteristics by which L. 

 badensis (Gottsche) Schiffn. {J ungermannia acuta, A. Lindenb.; /. 

 luridida Wils.) may be distinguished most readily from L. turhinata 

 (Raddi) Steph., wi'th which it has been much confused; and he ap- 

 pends its distribution. A, Gepp.
