ramenta, whose basal portion is slightly narrowed like a pedicel in the 

 latter species. C. sedoides which shows no resemblance in the form of 

 ramenta has distichonsly opposite arrangement of ramenta and pseudo- 

 constriction of the rachis which are in some measure similar to O. 

 ambigua and G. Okamurai. Madme. Weber remarks that the present 

 plant has the characters of different member of this large family ; and 

 indeed it may be taken up as a type of a new section. But from general 

 aspect of the plant, I am of opinion that this plant may be more safely 

 placed under the section Sedoideae with a little modiBcation of the 

 diagnosis of that section.
