C. Backii. Finally the terminal androgynous spike A is 

 equivalent with the same, A, in this species, and the utriculi, 

 painted black in the figures, correspond to those of C. Backii. 

 We might even go still farther and confine ourselves to the upper- 

 most lateral branch in C. Backii (B in fig. II), which showed the 



EXPLANATION OF FIGURES. 



FlG. I. Carex cladostachya Wahlbg., lateral branch of inflorescence, enlarged. 

 A = the terminal, B, C and D = the lateral spikes, all androgynous with the 

 male flowers at the top; P = clado-prophyllon : L = leaves, the lowest one 

 removed. Utriculus is painted black in all the spikes. 



Fig. II. Carex Backii Boott , the complete inflorescence of a single shoot, 

 enlarged. Letters as above ; the leaves (L) have been removed. All the spikes 

 are androgynous with the male flowers at the top ; the uppermost lateral spike 

 (B) is developed upon the rhacheola of an abnormal utriculus, of which the 

 female flower is merely rudimentary. Utriculus is painted black. 



Fig. III. Carex cedijiostyla Duv.-Jouve ; the terminal inflorescence, showing the 

 zigzagged rhachis and the leaf-like bracts ; copied from Duval-Jouve, but reduced 

 one-half.
