sporangiferi magis decompositi ramellisque inferioribus elongatis 

 fere dichotomi adparent, fasciculati et subfastigiati, in ramellis dis- 

 tortis tetrasporangia pauca, singula serie longitudinali disposita 

 foventes. Cystocarpia subglobosa et fere depressa. Tota superficies, 

 ramulis vix exceptis, reticulato-venosa, articulis translucentibus 

 diametro brevioribus; transversali sectione siphones pericentrales 

 ssepius 12, corticis evidenti strato cincti, adparent. Jam illustris 

 J. Agardh in nonnullis speciminibus siphones pericentrales 8 nu- 

 meravit, cortice evidenti cinctos; observationem cel. phycologi sue- 

 cici nuperrime clarus Falkenberg confirmavit. Color purpureus, 

 expositione in olivaceum tendens, exsiccatione nigrescens. Recens 

 planta est rigidiuscula ramulis subdivaricatis, ut bene observat 

 Harvey, guttam aquse inter ramellos retinentibus, qua de causa 

 specimina mox ex aqua extracta nitorem peculiarem monstrant.

 p. 111. - Fronde corymbosa, ramis subpinnatim egredientibus 

 inferne mox corticatis, superne fasciculato-penicillatis mollissimis, 

 articulis 8-12-siphoniis, extus strato corticali cinctis, diametrum 

 aequantibus aut parum longioribus, siphonibus pericentralibus serie 

 minorum a centrali separatis; cystocarpiis ovatis, pedicello brevis- 

 simo (uniarticulato) suffultis. 



Hab. ad insulas « Chatam » (Travers). — E caule, crassitie 

 pennam passerinam sequante, rami numerosi subpinnatini prove- 

 niunt iterum iterumque subdivisi, terminali coma subcorymbosa 

 penicillati ac mollissimi, articulis in his diametro circiter asquali- 

 bus parumve longioribus, adparenter 4-siphoniis. Siphones (in ramo 

 minori transverse secto) 8-12 in orbem circa centralem validiorem 

 dispositi, extrorsum strato corticali cincti, interstitialibus filis, tum 

 centralein siphonem cingentibus tum ramis ad stratum corticale 

 excurrentibus, inter siphones pericentrales et invicein subreticula- 

 tim junctis, sat conspicuis. Cellulse strati corticalis verticaliter sub- 

 longiores. Stmctura quasi Polysiphonim Brodicei.
