126 Notes on Alg&. [zoE 



sporic plant seems sufficiently characteristic to allow it to be 

 reckoned among the members of our Californian algal flora, to 

 which we may expect to see added still other species of Southern 

 Europe 



sEodes nifidissima J. Ag. The membranous Rhodophycese, 

 both larger and smaller, of the Pacific Coast of North America 

 present many problems of identity, which have occupied the 

 attention and taken much of the time of the writer for several 

 years, The various forms and species of Dilsea, Grateloupia, 

 Callymenia, Iridtea, etc., are very perplexing to unravel. One 

 of the largest and most beautiful of these is the plant referred to 

 the New Zealand species, sEodes nitidissima, which is abundant, 

 at times, near Pacific Grove, and also near San Pedro, California. 

 The frond has the shape of the typical Iridcea laminarioides, is 

 rather softer and brighter red purple; more like that described 

 for /. punicea, but which has the cystocarps and tetrasporangia 

 of one of the Grateloupiace£e. Some fronds reach a length of 

 nearly a meter, and a breadth of from 25 to 30 cm. Both tetra- 

 sporic and cystocarpic specimens are frequent in the collections 

 made and sent to the writer. This species was first collected on 

 the beaches in the vicinity of Pacific Grove, by Mrs. J. M. 

 Weeks, in September and November, 1897, and later collections 

 were made by the writer in May, 1898. Miss S. P. Monks col- 

 lected it on the beaches at San Pedro, also, in 1897: All the 

 specimens, seen by the writer, were cast ashore, in the autumn 

 and in the spring, after heavy storms. 



The Californian specimens have been compared by Professor 

 Farlow and the writer, with New Zealand specimens sent out by 

 Professor Agardh, himself, and apparently of the original col- 

 lection, in Herb. Farlow. ALodes nitidissima, then, is the third 

 species of the same region of the southern hemisphere to be 

 detected on our shores; the others being, Rhodoglossum polycar- 

 pum (Harv. ) J. Ag. and Nitophyllum Harvey anum J. Ag. It 

 seems likely that there are others to be discovered: 



Dilsea pygmzea Setchell mss. Fronds biform, consisting of a 

 prostrate and an erect portion. Prostrate frond tightly adherent 

 to the substratum, at first orbicular, then more or less lobed at the
