122 COLLINS AND HERVEY. 



pointed, the base sharply distinct from the lower sterile part of the 

 ramulus, which la usually about half the diam. of the fertile part; 

 ents of pericentral cells showing indistinctly through the corti- 

 catioD in the youngest portions only; dense fascicles of short, unicel- 

 lular rhizoids Issuing from all portions of the plant; color pale red; 

 substance rather firm. Type in Collins herbarium, No. s l»<>7. Shelly 

 Bay, -Ian. 10. 1913, Hervey; also at North Shore near WlstOWe, 



.Ian.. Feb., Hervey; dredged in 18 meters, Dec., Collins. 



The cylindrical frond- ami the absence of apical pit- place this 

 plant in the subgenus Euchondria Falk.; the abundant rhisoids are 



of the same type as in the genus Herpochondria t hut there is neither 



the dorsiventral Structure nor the lateral adherence of the latter. 

 The rhizoids may occur in short cylindrical fascicles, or may form a 

 dense mass along the frond for a distance equal to several diameter-; 

 they may occur on branches of any order, even on the stichidia with 

 mature tetraspores.

 In the plants collected at Gravelly Hay in December, were found 

 tetraspores, which have not before been recorded for the species; 

 they are tripartitcly divided, and formed from one of the pericentral 

 cells of a ramulus, quite as in Polysiphonia, hut occurred singly, not 

 in -eric-.
