This ])laTjt, one of the most beautiful on onr coast, is very 

 (iommon on the shore of the Sagami Bay. The fronds attain the 

 height of 12-15 cm. with rather long stipes. The articuli at the 

 basal part are short and cylindrical which gently Hatten upwards and 

 becomes provided with pinnule at each corner of the upper angles. 

 The pinnae are flat and very regular in their shape, just like a pectoral 

 tin of a common fish. But in the upper portions they are a little 

 changed, being sometimes linear, spathulate, often bifurcating at 

 the apex. 



Conceptacles are generally solitarily immersed at the apexes of 

 the pinnules, but not seldom in an axial articulus. 



It is necessary to notice that this plant is a species somewhat 

 apart from the ordinary Cheilotiponun. Cheiloaponmi , strictly si)eaking, 

 has no pinnules. Xevertheless, we often find the enormously pro- 

 longed and finally jointed lobes in those plants which belongs to the
