perigynium ; the latter character is somewhat unusual 

 in the grex Aeorastacliyce, but seems common to sev- 

 eral of the New Zealand Carices, notably in the grex 

 Echinochlaenco, nob.^ 



C. tuminensis. 



Meinshausen^ credited C. ternaria to the island Sacha- 

 lin, but according to KiikenthaPs monograph (p. 369), 

 the plant in question is Komarow's C. tuminensis. It is 

 a near ally of G. ternaria, and the distinctive characters 

 depend merely upon the pistillate scales being '4anceo- 

 latae subacutae cupreae nitidae/' and ^'utriculi squamis 

 breviores latiores, rostro subintegro^' in C. tuminensis, 



C. suhdola. 



This species shows the same habit as C. ternaria, and 

 according to Boott^ the squamae and the perigynia show 

 the following structure : 



"Perigyniis ovalibus vel ovatis rostellatis, ore integro vel 

 emarginato, stipitatis nervatis ferrigineo-punctatis, squama 

 oblongo-emarginata aristata vel ovata acuta vel obtnsa mutice 

 purpureo-pellucida lineata nervo viridi longioribus vel subae- 

 quantibus. " 



Regarding its affinity Boott states, that it is interme- 

 diate between C. Gaudichaudiana and the small forms of 

 G. ternaria. The accompanying figs. 10 and 11 show the 

 squama and utriculus. 



In some specimens kindly presented to the writer by 

 Professor T. F. Cheeseman (Auckland, New Zealand) 

 some of the pistillate spikes bore secondary spikes below 

 the terminal ; these secondary spikes were purely pistil- 

 late, subtended by filiform bracts, and sessile in some 

 distance from each other.
