Phacotce. 



Characteristic of the species of this section is the ter- 

 minal spike being gynaecandrous, even if not constantly 

 so. The lateral spikes are single, not fasciculate ; the 

 squamae of the pistillate flowers are mucronate or 

 aristate. The perigynium is membranaceous, ovate to 

 obovate, mth a generally short beak, entire to emar- 

 ginate. The section is represented by C. phacota 

 Spreng., C. incisa Boott, C. cernua Boott, C. praelonga 

 C. B. Clarke, C. Prescottiana Boott, and C. Kiotensis 

 Franch. et Sav. 



They are natives of southern and eastern Asia; C. 

 praelonga inhabits the Himalayas ; C. incisa and C. 

 Kiotensis Japan, while the remaining occur both in the 

 Himalayas and Japan. The accompanying drawings 

 illustrate the structure of the squama of the pistillate 

 flower of C. phacota (fig. 6), and of C. praelonga {^g. 8), 

 taken from about the middle of the spike ; at the base of 

 the same spike the mucro becomes an arista. The perigy- 

 nia show only the two marginal nerves (figs. 7 and 9) 

 except in C. Prescottiana ^ where several fine nerves 

 traverse the perigynium. 



Ternarice. 



In this section we meet with species in which the pis- 

 tillate spikes are fasciculate : Car ex ternaria Forst., C. 

 tuminensis Kom., C. suddola Boott, C. Darunnii Boott, 

 and C. Arnottiana Nees. 



The geographical distribution of these species is very 

 scattered: C. ternaria and C. suhdola are indigenous to 

 New Zealand; C. tuminensis is a native of Korea; C. 

 Arnottiana of Ceylon, and finally C. Darwinii is known 

 from Chile, Argentina and Straits of Magellan. 



C. ternaria. 

 Boott^ describes the species as follows :
