1. Wrangelia Lyallii, Harv. ; fronde setacea flaccida fere e basi pellucide articulata ecorticata in parte 

 inferiore venulosa pinnatim vel bipinnatim ramosa, ramis elongatis simplicibus ad nodos opposite vel verti- 

 cillatim ramellosis, ramellis pinnatis, pinnis oppositis patentibus parum attenuatis obtusis subacutisve, arti- 

 culis ramorum diametro multiplo, ramellorum 6-8-plo longioribus, tetrasporis ad pinnas ultimas sessilibus 

 solitariis vel fasciculatis triangule divisis, cystocarpiis minutis terminalibus fere nudis (vix involucratis) . 



Hab. Euapuke and Preservation Harbour, Lyall. 



Frond 4-5 inches long, thicker than hog's-bristle, once or twice pinnated; the branches long, virgate, and sim- 

 ple. Stem veiny near the base, pellucidly articulate above, and all the branches pellucidly articulate, with narrow 

 endochrome and thick cell-walls. All the nodes are furnished with opposite or whorled, patent, pinnated ramelli ; 

 the pinnee mostly opposite, rarely alternate. Colour a brilliant carmine. Tetraspores sessile on the inner faces of 

 the pinnEe of the ramelli, one, two, or more at each node. Cystocarps minute, terminating the rachides of nearly 

 naked ramelli. It closely adheres to paper in drying.— Allied to W. multifida and to W. crassa, but different. 



2. Wrangelia squarrulosa, Harv. ; fronde setacea rigida e basi articulata ecorticata distiche ramosa, ra- 

 mis alternis oppositisve pluries compositis nunc laxe ramulosis nunc creberrime pinnatis v. bipinnatis, pinnis 

 saspissime oppositis, articubs omnibus diametro 2-3-plo longioribus ad genicula ramellis minutis verticillatis 

 dichotomo-multifidis squarroso-spinescentibus obsessis, tetrasporis sessilibus in ramellos lateralibus. 



Var. a; decomposite pinnata, pinnis piimulisque creberrimis oppositis. 



Var. /3 ; vage ramosa, vix pinnata. 



Hab. On the beach at Preservation Harbour, both varieties, Lyall. 



The two varieties which we have here associated look to the naked eye very different, but not more so than 

 parallel varieties of D. penicillata j and the microscopic characters of each are so similar that we fear to separate 

 them. The squarrose ramelli, which densely clothe the nodes, are at first simple, become gradually branched, and 

 at last are excessively divided; they are about a quarter of a line long, whorled, and crowded together, giving a 

 beaded character to the nodes. Substance rigid, not strongly adhering to paper. 



Except in substance there is considerable resemblance in the general aspect to W. penicillata. Till the cysto- 

 carps shall be discovered, the genus must remain in some degree doubtful. Possibly CalMMmnion spinescem, Kutz., 

 may be an allied plant.
