Hab. In Louisiana, arborum truncis, Drummond. 



Caules subseniiunciales, erecti, aggregati. Folia patulo-re- 

 flexa, lineari-lanceolata, acuminulata, integerrima, canalicu- 

 lata, crassiuscula, nervo subcontinuo, siccitate valde crispata, 

 absque nitore. Seta brevis, foliis triplo longior. Capsula 

 erecta, oblongo-elliptica, ore rubro. Peristomii dentes ore 

 capsulse subimmersi, conniventes, late subulati, subinde per- 

 forati, apice vix fissi, externa facie trabeculati, saturate fulvi, 

 basin versus rubri. Calyptra campanulata, flavo-brunnea,

 Operculum e basi convexa rostratum, rectum, capsula paulo 

 brevius. 



The absence of an annulus in this species, the immersed 

 peristome, and the more crisped dry foliage are marks where- 

 by this Moss may be readily distinguished from G. crispata 

 and G. Muhlenhergii. In size it is intermediate.
