 tuhulosa, axi fiiisque periphericis constituta, juvenilis axili si-

 axili siphone sensim filis decurrentibus cincto; fila peripherica

 nere subjunxit. Ramuli minores sunt siphone centrali instructi 

 ramique majores tubulosi, axili siphone vix conspicuo aut sen- 

 sini subdiviso aut forsan potius disrupto, frondis tubo interiore 

 magis distento. Fila peripherica e siphone centrali exeunt et qui-

 ramorum decurrunt aBque articulata at tenuiora; hgec initio cum 

 axili siphone parallela, sensim magis oblique peripheriam versus 

 tendunt. In fronde tubulosa fila interiora omnia aut saltem plu-
