and stem which have cartilaginous consistence. In drying, the 

 frond does not adhere to paper. 



Phacel ocarptts japonicus may be placed in the subgenus 

 Euctenodus {Kg). J. ^g. in the neighborhood of Ph. Labillar- 

 dieri. On comparing the former plant with the latter, it differs 

 in several points, viz : by smaller statue of frond, by thinner 

 and softer substance, by less thickened midrib, by broaderness of 

 wing of branches, by shortness and more distant arrangement of 

 laciniae. The length of longer laciniae is, as stated before, about 

 I longer than the breadth of rachis ； and even in well-developed 

 ones, their bases are somewhat broader than the base of laciniae 

 of Phacelocarpiis Labillardieri. Lastly, the laciniae are more 

 widely separated and are much more spread than in the latter 

 species. 



In the point of its having broader wings of frond, the present 

 plant resembles Phacelocarpus alatus Harv ； but the latter plant 

 differs in having pedicels of the both kinds of fruits transformed 

 fromlacinice. Both Phacelocarptis apodus J. Ag. and Ph. sessilis 

 Harv. differs from the plant in question in having more slender 

 and subulate laciniae and the former species, moreover, in having 

 verrucose cystocarps. Phacelocarptis epipolceus Holm, resembles 

 to the present plant in the form, length and arrangement of 

 laciniae, but it differs in having thickened rachis and externally 

 invisible midrib as well as in the mode of ramification.
