244 BOTAXICAL GAZETTE [march 



Blake, 8 in "A revision of the genus Poly gala in Mexico, Central America, 

 and the West Indies/' recognizes 137 species, 39 of which are described as new. 

 There are also numerous new combinations and new names, and a general 

 reorganization of the classification. 



Brixton, 9 in connection with an account of the vegetation of "the little 

 known island of Anegada," one of the Virgin Islands, has described a new 

 Acacia {A. anegadensis) and a new lichen (Arthonia anegadensis). 



Britton, 10 in his eighth paper on West Indian plants, describes a new 

 Cy perns from Jamaica; lists the West Indian species (16) of Stenophyllus, 

 including a new species; lists the Cuban species (15) of Galactia, with 4 new 

 species; lists the Cuban species (5) of Machaonia, with 2 new species; presents 

 the Cuban genus Heptanthus, recognizing 6 species, 5 of which are new; and 

 publishes 5 new species from Porto Rico, 9 new species from Cuba, and 21 new 

 species from the Isle of Pines, by several specialists. 



Burt, 11 in continuing his studies of North American Thelephoraceae, 

 has monographed the genus Hypochnus, recognizing 31 species, 13 of which 

 are new species, and 12 are new combinations. 



Burt, 12 in his seventh paper on the Thelephoraceae of North America, 

 presents the genus Septobasidium. It does not belong to the Thelephoraceae, 

 because its basidia are not simple, but it is included "merely for the con- 

 venience of students of the Thelephoraceae." The North American forms 

 include 17 species, 10 of which are described as new. 



Christensen 13 has described a new genus (Maxonia) of ferns founded 

 on Dicksonia apiifolia Swartz. The species (M. apiifolia) is represented by 

 specimens from Jamaica and Cuba, while a variety (M . apiifolia duale) occurs 

 in Guatemala, and is Nephr odium duale Donn. Smith. 



Dixon 14 has reported upon a collection of mosses from Borneo, showing 

 that our knowledge of the moss flora of the tropics is comparatively meager. 

 The list includes 133 species, 13 of which are described as new. Attention is 

 called especially to the "peculiar ecological distribution of the remarkable and 

 striking genera Syrrhopodon and Calymperes." — J, M. C.
