The vegetations often robust. The ramification is either 

 dichotomous (individuals in sheltered water) or irregular with devel- 

 opment of main axes. Secondary 

 shoots are frequent though without 

 affecting the habitus of the species. 

 The uppermost zones often not 

 separated. The zones below these 

 in the upper part of shoots are 

 provided with margins which are 

 growing both upwards and down- 

 wards. The zones in the middle- 

 most and lower parts resemble 

 those of C. Areschougii and fruti- 

 culosum. Yet the lower margin is 

 not always sharp, but often it 

 grows out in tongues. Yet the 

 aspect of these zones are as in the 

 two above-named species. The 

 bark is at last confluent. The axial 

 cells are in the lower parts up to 

 9}h mm. long with zones of the 

 same height. The bark consists in 

 the outermost parts of small cells 

 c. 7 — 10// long (material from Her- 

 barium) usually stretched length- 

 wise. No special proteid-containing 

 réfringent cells. 



Tetraspores in one or more 

 series sometimes in the apices of the shoots, which in this case 

 are straight. 



Gystocarps without any characteristic; antheridia not observed. 

 Hairs are common. The colour rusty red.
