* In the Supplement to the 1st volume of Bridel's ' Bryologia Universa ' 

 the two following gymnostomous mosses are described, and said to grow 

 near Dax : — 



" Gymnostomum homomallum, Brid. ; caule erecto simplicissimo, foliis 

 lanceolatis acutis integerrimis supremis e nervo crasso excurrente longissime 

 subulatis secundis, thecae oblongae operculo conico-rostrato incurviusculo. 



" Circa Dax ad terram caespitosam legit D. Grateloup ; clar. Candolleus 

 communicavit. 



"A Didymodonte homomallo, quem habitu proximo refert dignoscitur sta- 

 tura duplo minore, caule simplicissimo, foliorum supremorum longitudine et 

 areolatione, prasprimis stomate nudo." — I?r. Univ. 1. p. 757. 



May not this be Trichostomum sjihulatum, Bruch, with which it agrees 

 well enough except as to the peristome, which may have been overlooked ? 



"Entosthymenium, Brid. 



" Caracter esseiitialis. Stoma externe nudum ; interne membrana angusta 

 annulari margine tandem lacinulata instructum. Calyptra cucuUiformis. 

 Theca subinsequalis, apophysata. 



" E. tristichum, Brid. ; caule erecto ramosiusculo, foliis patentibus sicci- 

 tate incurvis subtristichis ovato-lanceolatis acutiusculis solidinerviis, thecae 

 ovatae subinclinatae apophysi basilari parva. 



*' In Gallia australi circa Dax D. Grateloup detexit ; Candolleus commu- 

 nicavit. Caespitibus fastigiatis vivit. 



" Barhulam e toto habitu, foliorumque forma et areolatione diceres, at 

 membrana annularis et apophysis proprium genus declarant." — Br. Univ. 1. 

 p. 761. 



I confess myself unable to form a probable guess as to what this moss 

 really is : the possessors of the Bridelian herbarium must decide.
