 p. 5, t. 12, f. c-e (non Grateloup nee Crouan). — Fronde subse- 

 tacea, dichotoino-ramosa, diffusa, ramis patentissimis, superioribus 

 vage secundatis, terminalibus indivisis rectiusculis subulatis, arti- 

 culis inferioribus diametro 2-3-plo longioribus dense corticatis. 



Hab. in mari Indice occidentalis, Coralliis adnata (A.spegren); 

 ad Jamaicam (Swartz), ad insulain St. Crucis (IUvn, Benzon, 

 Oersted); ex Antillis, absque exacta indicatione loci (Kuetzing). 

 — l<Yons intricato-caespitosa diffusa, setam crassitie haud sequans, 

 sublateraliter ramosa ramisque excrescentibus dichototna, superne 

 subincurva, ramis externo curvatune latere s;epe secundis, lere 

 horizontaliter egredientibus, secundatim parce divisis, apicibus por- 

 rectis indivisis subulato-attenuatis. Articuli ubique corticati, cellulis 

 rotundatis minutis fere puncta oemulantibus, inferiores usque 3-plo 

 diametro longiores, interstitiis minus intense coloratis, superiores 

 diametro ;equales et breviores. Tetrasporangia (sec. Montagne) to- 

 tum ramellum occupantia, transversim subquaterna et strato cor- 

 ticali immersa. Cystocarpia (si synonyma allata revera ad hanc 

 speciem pertinent) in ramulis superioribus lateralia, ramellis sub- 

 ternis, apice paullum involutis fere duplo longioribus cincta. Color 

 iniiiiato-rubens, sa^pe nitens. Substantia videtur gelatinosa, unde 

 exsiccatione subcartilaginea; apices (et s;epe planta inferiori com- 

 pressi apparent, forsan exsiccatione collapsi. 



B. Genicula ramorum juvenilium (et prolificantium) calathiibrmia, sat conspicue 

 distincta adultiorum mox confluentia. 



1. Tetrasporangia in ramis vix mutatis obvenientia.
