 phoniis ad « Colombo » insula) Ceylonse (Exped. Vettor Pisani, 

 Piccone); ad « Nagasaki » Japonias (Schottmueller, Martens). — 

 Csespituli pulvinatim expansi, 4-5 cm. altitudine asquantes, fron- 

 dibus dense conjunctis constituti. Frondes millimetro latiores, basi 

 teretiuscuke, superne evidonter compress^e, sectionem transversalem 

 ancipitem offerentes, a basi ad apicem dicliotomiis 4 millim. cir- 

 citer distantibus decomposita3, subregularitcr fastigiatne et flabel- 

 latim expansa^, sed varie flexte et haud strictaa; segmenta termi-

 mersa, nodose prominentia, per totam fere frondem longitudinaliter 

 seriata, invicem distantia, singula latitudinem frondis fere occupan-

 stral. tab. 290, -T. Ag. Epicr. p. 209. — Fronde pulvinatim ca^spi- 

 tosa, minuta, tereti, dichotomo-fastigiata, segmentis superioribus sne- 



pe adproximatis et fasciculatis, terminalibus teretiusculis acutis; 

 cystocarpiis infra apices simplices singulis aut concatenatis, soepe 

 infra furcam bicornibus, circuincirca prominentibus. 



Hdb. ad littus Tasmaniae (R. Gunn). — Callus radicalis exi- 

 guus, disciformis. Frondes casspitosas, usque ad 4 cm. altoe, seta-

 Color obscure rufescenti-brunneus. Substantia rigidissima, in sicco 

 cornea. De pertinentia hujus speciei ad genus Gymnogongnim 

 dubitat clarus J. Agardh, qui eam potius Ahnfeltice adscribendain
