508 Howe: Phycological studies 



J. Agardh has remarked that in habit Fauchea nitophylloid.es 

 suggests Rhodophyllis bifida or narrow specimens of Nitophyllum 

 ocellatum. It may be said that F. (?) mollis suggests the broader 

 conditions of these species. In structure F. (?) mollis is not very- 

 different from certain species of Gracilaria of J. Agardh's sub- 

 genus Podeum, section Rhodymenioideae, but the cell walls and the 

 frond as a whole are softer and more gelatinous than in any Graci- 

 laria that we are familiar with and the large cells of the medulla 

 are more hyaline and vacuous than is customary in that section of 

 Gracilaria. 



Laurencia paniculata (Ag.) J. Ag. Sp. Gen. et Ord. Alg. 2: 755. 



1852 



Chondria obtusa paniculata Ag. Sp. Alg. 343. 1822. 



La Paz, Vives 22. 



Plants rather more slender and ultimate branchlets more 

 elongate than in specimens from La Jolla, California, distributed 

 in Phyc. Bor.-Am., no. ioqj. 



The current name for the species is used here provisionally, 

 though the specific name appears to depend for its priority on its 

 publication as a varietal name, which violates all of the current 

 codes of nomenclature. Two older names in the specific category 

 that are commonly cited as synomyms are Laurencia patentiramea 

 (Mont.) Kiitz. and L. glandulifera Kiitz., but the older of these, 

 L. patentiramea, according to Montagne's original figure, does not 

 apply very accurately to our Baja California plant and there are 

 possibly grounds for doubting the alleged synonymy. The elon- 

 gate ultimate branchlets of the Vives plant are rather suggestive 

 of those figured by Kiitzing (Tab. Phyc. 15: pi. 63. f. a, b. 1863) 

 for his L. paniculata, but they are not distichous or pinnate. 

 Kiitzing's Laurencia paniculata, which, by the way, antedates J. 

 Agardh's, is referred to L. pinnatifida by De-Toni; J. Agardh first 

 cited it as a doubtful synonym under his own L. paniculata, but 

 afterward (op. cit. 3: 651) omitted to refer to it. 



Polysiphonia californica Harv. Ner. Bor.-Am. 2: 48. 1853 

 San Felipe Bay, D. T. MacDougal, Feb. 1904. 

 The specimens are a little more luxuriant than Harvey's type
