Merrill: Plants of Guam 
MUSCI 
Mr. Salford, page 327, enumerates nine species of mosses from Guam, 
collected by Gaudichaud and reported by Schwaegrichen in Bot. Freyc. 
Voy. (1826) 226-229. In a number of cases I cannot, from the literature 
available here, refer these to their genera as understood to-day. The follow- 
ing is Safford’s list: 
Bartramia unc\nata=Philonotis 1 
Hypnum cupressiforme. 
Hypnum delicatu!um = Tliuidium. 
Hypnum recurvans Schwaegr. =Rhaphidostegium recurvans Jaeg. 
Hypnum scaturiginum —Ectropothecium scaturiginum Jaeg. 
Macromitrlum urceolatum Schawegr. 
Neckera undu\ata=N eckeropsis lepineana. 
Octoblepharum albidum Hedw. 
Syrrhopodon rigescens. 
From the known ranges of these species, it seems to be evident that a 
number are erroneously identified. The following species, all determined 
by Dr. V. F. Brotherus, are represented in our Guam collections: 
Neckerop&ls lepineana (Mont.), McGregor 625. 
Macromitrium semipellucidum D. & M., McGregor 626. 
Syrrhopodon revolutus D. & M., McGregor 623. 
Thuldium plumulosum (D. & M.), McGregor 622. 
Ectropothecium mariannarum Broth, sp. nov. ( McGregor 627).
