In form of frond, CtUleria adspersa (Roth) De Not., on the 

 one handj has flabellate, multilobed and Zondr/a-Yike frond which 

 shows tendency, in adult state, td/pass into a form somewhat" 

 resembling to Gut. multifida (Sm.).'Grev. as it is shown in Zan さ r- 

 dini's I—con. Phyc. Meditr.-Adr., Tav. LVII. Cutler ia pacific a Grun. -、 

 on the other hand, has thin-membranaceous, linear, dichotomous 

 and elongated frond, while し ut. compressa Kg. has compressed, 

 coriaceous and dichotomous one. Now, Cutlefia cylindrica, as 

 its name indicates, has cylindrical frond, and may perhaps be 

 allied with Cut. pacijica or compressa. By the discovery of the 

 present plant, the genus— Ctttleria comprises, in regard to the 

 form of frond, three variations, namely, fan-shaped, compressed 

 and cylindrical, and also, in respect to the structure, three diver- 

 sities, i. e., dorso-ventral ; bilateral and radial.
