A R. membranacea, Harv. tetrasporangiis in 

 distincta. 



Species submembranacea, mediocris magnitudinis, flabellatim 

 vel jrregulariter ramosa ; from duobus distinctis cellularum 

 atratis contexta, cellulis interioribus majoribus per duas series 

 frondis piano parallelas dispositis, cellulis corticalibus minutis 

 aspectu rosulato -areolato a superficie desunt ; rami 5 mm. lati, 

 subdichotomi yel flabellati, margine integro, segmentis termina- 



istioribus obtnsis ; venae nullae ; cystocarpia incognita ; 

 tetrasporangia sec as mediam paginam incrassatam fere in soro 

 disposita, 40 x 20 /*. Color brunneo-ruber. 



^ J orni this 8 P ecies often resembles R. membranacea, Harv. 

 It differs from it however both in the structure of the frond and 

 the position of the tetraspores. The cortex is distinct, and is 

 composed of a uniform layer of minute cells, which entirely covers 

 the inner tissue. A true rosulato-areolate arrangement is not 

 present, though the outline of the larger cells beneath is very 

 obvious. R membranacea, Harv., differs in the punctate thallus, 

 and incomplete cortex. In the arrangement of the tetraspores 

 the present species approaches the Australian R. Brookeana, 



tK , ch it is perhaps most nearly allied ; it differs from it 

 in the structure of the frond.
