North American Muscineae. — C. C. Haynes* gives an obituary 

 notice of Professor L. M. Underwood (b. 1853, d. 1907), with special 

 reference to his work in connection with the North American Hepaticse, 

 and appends a bibliography of his works. A. W. Evans, f having re- 

 cognised Lopholejeunea Muelleriana among some hepatics collected by 

 S. Rapp, of Sanford, in Florida, points out certain details in which it 

 differs from specimens gathered in Porto Rico and Brazil. Twenty-nine 

 Lejeuneas are now recorded for the United States, and twenty-four of 

 them for Florida. A. Lorenz % publishes some notes upon Jubula 

 pennsylvanica, illustrated for the first time with figures. P. M. Towle § 

 gives data about the fruiting season of a few species of mosses, chiefly 

 Mnium, Rhodobryum, and Bartramia ; and shows how the dates differ 

 according to latitude, climate, and the earliness of arrival of spring. 



E. G. Britton |] gives a history of the various opinions that have been 

 published about the presence or absence of the genus Zygodon in North 

 America, and the number of species found. She sums up the matter by 

 providing descriptions of three species — Z. viridissimus, Z. rupestris, 

 Z. gracilis — and of Leptodontium excelsum, which is usually known as 

 Zygodon Sulivantii. A. W. Evans, IT having had an opportunity of 

 examining the type specimens in the Lindenberg collection of Hepaticae 

 at Vienna, and having arrived at some conclusions which are at variance 

 with those of recent writers and with his own previous ideas, writes upon 

 the synonymy of three North American species. 1. Lejeunea Icetevirens 

 Nees and Mont, is the same as L. lucens Tayl. and L. glaucophylla 

 Gottsche, and belongs to the genus Microlejeunea. 2. L. claiisa Nees and 

 Mont, is the same as L. opaca Gottsche, L. commutala Gottsche, and 

 D. lutea Mont., and should be referred to Euosmohjeunea. 3. Frullania 

 obcordata Lehm. and Lindenb. is the same as F. caroliniana Sulliv. and 



F. Martiana Gottsche. A. Lorenz ** gives figures of Marsupella Sidli- 

 vantii and M. sphacellata, with explanatory notes. 



New South Indian Moss.ft — H. N. Dixon describes Brachy- 

 me nium turgidum, a new species from the Western Ghats. It is a very 

 distinct species, characterised by a turgid subpendulous capsule, and by 

 the leaves being narrowly margined and entire, and not spirally twisted 

 when dry. 



Tundra-forms of Hypnum.JJ — W.Monkemeyer discusses the tundra- 

 forms of Hypnum exannulatum, and distinguishes a var. pinnatum f. 

 tundra, and a var. brachydictyoa f. tundra, giving a description of each 

 and adding critical notes on various specimens. 



Type Species of Stereohypnum.§§ — M. Fleischer publishes the basis 

 of a monograph of the genus Stereohypnum, which is also known as Micro- 

 thamnium. This genus is rendered extremely difficult owing to the
