1X, C, 1 Merrill: Plants of Guam Al 
MUSCI 
Mr. Safford, 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 3 
available here, refer these to their genera as understood to-day. The follow- q 
ing is Safford’s list: ri “ 
Bartramia uncinata=Philonotis ? 
Hypnum cupressiforme. 
Hypnum delicatulum=Thuidium. 
Hypnum recurvans Schwaegr.=Rhaphidostegium recurvans Jaeg. S 
Hypnum scaturiginum=Ectropothecium scaturiginum Jaeg. 3 
Macromitrium urceolatum Schawegr. 
Neckera undulata=Neckeropsis 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: 
Neckeropsis lepineana (Mont.), McGregor 625.. 
Macromitrium semipellucidum D. & M., McGregor 626. 
Syrrhopodon revolutus D. & M., McGregor 628. : 
Thuidium plumulosum (D. & M.), McGregor 622. Bi " 
Ectropothecium mariannarum Broth. sp. nov. (McGregor 627). =
