Ferns of Ruwenzori.* — R. Pirotfca gives an account of the ferns 

 collected on Mount Ruwenzori during the expedition of Prince Luigi 

 Amadeo of Savoy, Duke of the Abruzzi. Twenty-five species are 

 enumerated, and were all collected in the Mobuku Valley. Four of 

 them are new to science. 



Ferns of the Far East.f — H. Christ publishes an account of some 

 collections of ferns from the Far East, viz. :— 1. 122 species collected 

 in Corea by Faurie and Taquet ; nine of these are new, and are accom- 

 panied by descriptions. 2. Twenty-five species from the island of 

 Saghalien, collected by Faurie, including two new species. 3. Eighty- 

 three species collected in the neighbourhood of Pin-Fa, in South China, 

 by Cavalerie, eleven being new species. 



New Species of Malesian and Philippine Ferns. i—H. Christ pub- 

 lishes descriptions of five new species of ferns collected in Luzon, 

 Penang, Perak and Saigon, by C. G. Matthew in 1906-8.

Relationship of Liverworts to Ferns.§ — E. Lampa discusses the 

 relation .between the liverwort-thallus and the fern-prothallium. It is 

 held by many that the liverworts, though apparently more simple 

 morphologically, yet developmentally stand higher than the mosses. 

 This view is supported by the fact that the anatomical structure of the 

 liverworts represents a degree of organisation superior to that of the 

 mosses. A further confirmation of this view is to be found in the onto- 

 genesis, which indicates that the apparent morphological simplicity of 

 the liverworts is to be regarded as a reduction from a higher degree of 

 development. The author throws further light upon this by her inves- 

 tigation of the germination of the spores of PeUolepis grandis, and finds 

 therein evidence of a clear relationship of the liverworts to the ferns. 



Sporogonium and Gametophore of Conocephalum.|] — M. Graham 

 describes her investigations as to the development of the sporogonium 

 of Conocephalum conicum, and also of the adjacent tissues of the 

 gametophore, in order to determine the origin of the sheath which 

 surrounds and incloses the calyptra, and to prove whether it bears any 

 relation to the pseudo-perianth found in Marchantia and Preissia. She 

 finds that this sheath in Conocephalum is not to be confused with the 

 pseudo-perianth of Marchantia and Preissia which arises from cells 

 immediately beneath the base of the archegonium, cells descended from 

 the original cell from which the mother-cell of the archegonium was cut 

 off. The sheath in Conocephalum arises from the gametophore tissue 

 surrounding the archegonium, and consists of several distinct lamina? 

 which are morphologically walls of air-chambers. The function of tlie 

 sheath is doubtless to protect the sporogonium through the winter.
