NO. 1 steere: bryophyta 3 



Calymperes Richardi C. Mull., Syn. Muse. 1 : 524. 1849. 



Costa Rica (West Coast) : Growing high in a tree, among orchids, 

 Port Baker, near Salinas Bay; 24-25 March 1939; F, H. Elmore No. 

 39-752. 



Distribution: Southern United States; West Indies; Central 

 America ; northern South America. Although this species is widely dis- 

 tributed in the American tropics, it has not been reported before from 

 Costa Rica. 



Erpodiaceae 



Erpodium domingense (Brid.) C. Miill., Bot. Zeit. 1 : 774. 1843. 



Mexico (West Coast) : On soil with a small fern, mixed with 

 Fissidens Garberi Lesq. & James, three-quarters of a mile up the canyon 

 from the landing place, Braithwaite Bay, Socorro Island, Revillagigedo 

 Islands; 18 March 1939; F. H. Elmore No. 39-7 51a. Only one small 

 stem of this unmistakable moss was found, but it was enough to establish 

 the identification beyond any doubt. 



Distribution: Cameron County, Texas; Santo Domingo; Haiti; 

 Puerto Rico; Yucatan; Guatemala. This is the first collection and 

 report of what has always been considered to be a typically Caribbean 

 species from the Pacific side of Central America.

 Beach Road; 18-20 April 1939; W. R. Taylor No. 39-767.

 South America ; Galapagos Islands. Although this species is known from 

 the West Indies, I do not believe that it has been reported previously 

 from Trinidad.

 15:28. 1912.
