changed the name to Haloglossum Griffithsianum which accordingly 

 becomes the type of the genus. The chief distinction between Halo- 

 glossum and Asperococcus lies in the character of the interior of the 

 frond. The former is ligulate and solid and the latter is saccate. Mrs. 

 Griffiths expressly states {loo. cit.) "there is not the slightest tendency 

 to be tubular or inflated," in speaking of A. compressus. We feel 

 inclined to keep the two genera separate, based mainly upon this 

 character, although the method of reproduction in the two is similar. 

 The genus Halorhipis is very similar in appearance and structure to 

 Haloglossum. but the sori are destitute of paraphyses although the 

 protruding zoosporangia are aggregated about a cluster of hairs. 



Halorhipis Winstonii (C. L. Anderson) Saunders 



Plate 35, fig. 8 



Fronds mostly aggregated into tufts, thin, membranaceous, lanceo- 

 late to obovate or spatulate, 8-20 cm. high, 2-5 cm. wide, about 200/x 

 thick, with very slender filamentous stipes; color dark olive green; 

 zoosporangia collected into sori mostly in slight depressions, ellipsoidal, 

 obovate or pyriform, 30-45/x long, 20-30/x broad; sori numerous, 

 variable in shape and size, linear to irregular in outline ; hairs in 

 groups in the sori ; gametangia and paraphyses unknown. 



Growing on the fronds of Egregia Menziesm and on rocks. Known 

 only from a single locality, Pebble Beach, Carmel Bay, California.

This plant, although known for only a little over a quarter of a 

 century, has had a somewhat varied history. It was first described 

 by C. L. Anderson (loc. cit.) who saw in it affinities with the genus 

 Punciaria Grev. Saunders (loc. cit.) next studied it and came to 

 the conclusion that a new genus, Halorhipis, should be erected for its 

 reception. It was distributed in the same year under that name in 

 the Phycotheca Boreali-Americana as no. 532. In 1910, as above 

 stated, Svedelius placed it in the genus Asperococcus Lamour. Our 

 studies, while leading us to retain the genus Haloglossum Kuetzing, 

 discarded by most of the later phycologists, and to place Asperococcus 

 compressus Griff, in that genus as a species distinct from all others,
