Mediterranean, comprising- 49 ferns and 24 fern-allies. He treats them 

 analytically, first arranging them in systematic order and stating their 

 general distribution. Then by means of lists lie shows their distrilmt ion 

 (1) in the different zones of altitudes; (2) according to the physical 

 nature of the soil ; (3) according to the chemical nature of the soil ; 

 (4) according to the humidity of the surrounding air ; (5) according to 

 the intensity of solar illumination ; (G) according to the temperature of 

 the surrounding air. And further, he shows in a table the comparative 

 frequency of each species in the five zones of altitude. 



Ferns of Styria.*— A_. von Hayek issues the first part of his flora of 

 Styria, a work which will comprise about 18 parts, more than 1400 

 pages, and will treat of the vascular plants of the province and the 

 geographical relations of the flora. The present part consists almost 

 entirely of an account of the ferns and fern-allies. A series of well- 

 defined keys to the various groups, genera, and species is supplied. The 

 descriptions (in German) are concise. Synonymy and the citation of 

 literature are sufficiently fully treated, while the habitat and distribution 

 of the species have been prepared with much care. Some of the groups 

 are illustrated with text-figures. 



Ferns of Mount Ruwenzori.f — R. Pirotta publishes diagnoses of 

 four new ferns collected on Mount Ruwenzori at an altitude of about 

 12,000 ft. during the expedition of the Duke of the Abruzzi. Their 

 names are Cyathea Sellm, Woodsia nivalis, Asplenium Duck- Apr utii, 

 Elaphoglosswn Rmvenzorii. 



Ferns of the Malay Peninsula-! — H. N. Ridley publishes a list of 

 more than 380 species of ferns recorded as occurring in the Malay 

 Peninsula, a region particularly rich in ferns owing to its wet tropical 

 forests. The richest localities are usually situated at altitudes of 

 1000-5000 ft. Most of the species occur also in the Malay Islands, 

 many also in the Mascarene Islands, as well as in India, Polynesia, and 

 South America. Six even are found in the British Isles. About 40 

 of the species are endemic in the Malay Peninsula. Notes on the 

 habitats and uses of the ferns are added. The local distribution, 

 collector's name, number, and native name are given under each species. 



Ferns of Argentina.§ — C. Hicken publishes some notes on Argentine 

 ferns. He gives a list of twenty-three ; among these are two species 

 and two varieties described for the first time.
