MARINE RED ALGAE OF PACIFIC MEXICO 



PART 2 



CRYPTONEMIALES 



(Continued) 



E. Yale Dawson 



The following represents a continuation of the studies of Pacific 

 Mexican Red Algae of which Part 1 ( Bangiales to Cryptonemiales subf. 

 Corallinoideae) was published recently in Allan Hancock Pacific Ex- 

 peditions, volume 17, number 1. The treatment of the Cryptonemiales is 

 here completed with the exception of the Melobesioideae. The difficult 

 study of these plants has been delayed awaiting the appearance of Lucile 

 Roush Mason's monograph of the species of this group occurring along 

 Pacific North America north of Mexico. 



The general features and some of the ecological relationships of the 

 marine flora of Pacific Mexico have been presented elsewhere by the 

 writer (Dawson 1944, 1949, 1951). The reader is referred to these 

 papers pending the appearance of a more comprehensive account of the 

 ecology and geographic distribution which is intended to follow the 

 systematic parts. 



All collection numbers cited with the prefix "D," are those of the 

 author. The dates of collection are as follows: 16-1094, January- 

 February 1946; 1095-1645, April 1946; 1646-1989, May 1946; 2756- 

 3145, October 1946; 3146-3581, November 1946; 3582-3764, December 

 1946; 3765-3940, January-February 1947 ; 5143-5312, September 1948; 

 6462-7278, 7795-7810, March 1949; 8124-8917, December 1949- 

 January 1950; 9044-9554, April-May 1950; 9624-10095, April 1951; 

 10279-10288, August 1951; 10289-10586, October-November 1951; 

 10672-10691, December 1951; 10742-11040, May-June 1952. Numbers 

 from series earlier than 1946 are followed by the last two digits of the 

 year of collection : 265-40. 



Distribution records are given from north to south for the sake of 

 consistency, the Gulf of California following Pacific Baja California. 



Representative examples of all collections cited are deposited in the 

 Herbarium of the Allan Hancock Foundation (HAHF) unless other- 

 wise indicated.
