 paulo diversa, nempe juvenilia et tetrasporangiis instructa sunt 

 anguste lancoidea cellulisque corticalibus ita laxis constituta, ut 

 plus minus hyalina adparent; effceta prolongantur (ut in toto genere 

 norma sit), evadunt lineari-lancoidea in acumen sensim et longe 

 attenuata; cellulte corticales sunt plures et densius disposita? quam 

 in parte tetrasporangifera atque plures in articulos conjuncta?, at
