diftance from each other, in an irregularly alternate manner, fhort, blunt, fimple, 

 iiTuing from the ftem at obtufe angles, and pointing upwards. The joints 

 throughout the whole plant are uniform, their length fcarcely greater than their 

 breadth, and with fomewhat of a beaded appearance. Thefe circumftances will 

 be fufficient always to diftinguifh it from C. cajianea, t. 72, to which at firft 

 fight it bears a ftrong refemblance. Great care is neceffary not to confound 

 either of thefe plants with the radicles, which fhoot out of the ftems of moft 

 fpecies of mofles that grow in moifl places, and are particularly abundant on 

 Bartramla fontana & Bryum palujlre. C. Orthotrichi is alfo very nearly allied to 

 C. Acharii & C. rubicunda of Roth, the latter of which may probably be the 

 C. Uichola of Englifh Botany. 



The texture of C. Orthotrichi is rigid and brittle ; and in drying it adheres 

 neither to glafs nor paper. T.
