dine aut immo sunt diametro breviores. Sectione transversali sipho- 

 nes 7 circa centralem conspiciuntur cortice nullo cincti. Tetraspo- 

 rangia in ramulis minoribus penicillatis evoluta, longitudinaliter 

 seriata sed unilateraliter prominentia adspectum tribuunt ramulo 

 quasi spiraliter tortum. Cystocarpia ad ramos superiores prove- 

 nientia, a ramulo transformata ideoque superiora a ramulo mi- 

 nori formata omnino sessilia, inferiora ramuli partem imam non 

 mutatam servantia, quasi brevissime pedicellata, globoso-ovata. 

 Antheridia in op. cit. descripsit Falkenberg. Color fuscescenti-pur- 

 pureus, exsiccatione nigrescens. Specimina exsiccatione chartse ar- 

 cte adhaerent. A BrongniarteUa byssoide, cui ob modum crescendi 

 hsec species similis, differt, observante J. Agardh, primo obtutu 

 quod articuli sunt breviores, unde penicilli, a geniculis exeuntes, 

 densiores obveniunt et pro filis verticillatis injuria habiti fuerunt.
