"328 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Eberhardt. Two of the species are new. He also gives a list of 13 

 mosses collected near Shanghai by Henry and Courtois, five of which 

 .are interesting as having been recorded from North Sheii-si. 



/ Orthomniopsis and Okamureea.* — V. F. Brotherus publishes 

 descriptions and figures of two new genera from Japan. Orthomniopsis 

 is a remarkable genus allied to Orthomnion, but very different from it in 

 the structure of its peristome. It has one species, 0. Japonica, collected 

 by Okamura on Mt. Kuishi, Tosa province, Shikoku. The other 

 novelty is Ohmiura'a, a most distinct genus, nearest to Forsstroemia, 

 but quite different in the structure of its peristome. Its one species, 

 0. cristata, was gathered in the same Japanese province. 



True Status of Philonotis mollis Vent.f — G. Desmier is preparing 

 a monograph of the French species of Philonotis. In studying P. 

 mollis Vent, he has discovered that most authors have misunderstood 

 that plant, probably through never having seen authentic specimens 

 • of it, and have regarded it as a variety of P.calcarea. He recapitu- 

 lates their views. He then shows that P. mollis is synonymous with 

 P. ccBspitosa, as had been indicated already by Yenturi and by Husnot. 

 P. ccBspitosa was first found and described by Wilson in this country, 

 and is not known from any but silicious habitats, whereas P. calcarea 

 is essentially calcicolous. Dismier defines the distinctive characters of 

 .the two species. 



Ephemerum stellatum Phil.| — I. Douin states that he has recently 

 •gathered this very rare little moss at five stations in France, and 

 that consequently it is less rare than has been supposed. It escapes 

 notice through being so minute. It grows on the silicious clay, upon 

 which he has found such other curious rarities as Prionolobus dpMtatus, 

 P. Turner i, Gephaloziella Douin ii, C. r/racillima, C. Bryhnii, Dichiton 

 galliciim. It is usually accompanied by E. serratum and E. steno- 

 phyllum var. hrevifolium. E. stellatum, originally discovered in France 

 by Philibert, was gathered by W. E. Nicholson at Crowborough, in 

 Sussex, and at Bedgbury, in Kent, in 1902. 



Weissia brasiliensis, a forgotten Species. § — I. Theriot has studied 

 the type of Weissia brasiliensis Uuby, a moss which was collected at 

 ,Bahia by Salzmann. It was described in 1H36, but has remained 

 almost forgotten for half a century, and its name has been invented 

 afresh for another moss. Theriot realised at once that it belongs to 

 a section of Microdus, and later found that it is identical with M. 

 pomiformis Besch., an Indian species originally named Didymodon 

 pomiformis by Griffith in 1840. According to the Vienna rules of 

 nomenclature, the species takes the name of Microdus brasiliensis, 

 though its principal habitat is in Asia— Himalaya, Khasia, Ceylon, 

 .Java. Theriot gives a new drawing of the Brazilian plant, but says 

 Duby's figure is good so far as it goes.
