78. Aneura Stephanii Besch. n, sp. 



Dioica, pusilla, flaccida et tenera, pallide virens, in corlice dense strati- 

 licata. Frons ad 5 mm. longa, pinnala vel bipinnata, cellulis internis per- 

 lucentibus grosse reticulata. Trimcus basi angustatus superne pro plantae 

 magnitudine latus, medio 3 cellulas crassus; alae 3 cellulas latae, cellulis 

 magnis, margine minoribus. Pinnds longae, lineares, remotse divergentes, 

 simplices, inlerdum furcatse, in apice frondis pro more approximatse et 

 flabellatim divergentes, alse ubique 2 cellulas latse, celluUs marginalibus 

 majoribus obtusae. Rami masculi pro planta longissimi, in pinnis ultimis, 

 terminales, interdum ex apice vegetativi et iteratim fertiles, valde nume- 

 rosi, ssepe omnes ramorum pinnulas occupantes, iineares tenerrimi et 

 maxime fragiles, margine erecto profunde papuloso vel subdenticulalo.
