in the above remarks spoken of the itp species as 
belonging to 5 ih genus Barbula, reserving until now the discussion 
plant. As 
early as 1859, Mitten, in Journ. Linn. Soc. iv. p. 72, removed 
Schwaegrichen’s species from Barbula to the genus Streptopogon, 
remarkin ng :-—' 8. mnioides Mitt. (Barbula Schwaegr.). The calyptra 
of this species resembles that of S. e ‘ythrodontus, to which it 1 
very closely allied.” In Hooker’s Fl. Tasmania, ii. p. 876 (1860), 
Mitten observed :—‘‘ 8. mnioides Mitt. Fertile plants of this curious 
moss, gathered in Chili by Lechler, have the fer Li see oe 
mitriform ; in other respects they agree well with Schwaegrichen 
figure. . This species is very closely allied to S. erthratont " 
Finally, i in 1879 (in Phil. Trans. Roy. Soc. Lond. vol. 168, p. 38), 
Mitten separated Schwaegrichen’s ‘apes from the other species of 
Streptopogon, observing as foéllows:—‘‘ 8. mnioides Schw. t. 310 
(Barbula) [differs from the other speiies of Streptopogon in having] 
the perichetial leaves much elongated, and different from those of 
the stem, simulating those of Holomitrium, tae on this account 
should stand apart from the other species, 
Streptopogon Wils. Theca in perichztio ® folii caulinis sub- 
similibus immersa, emergens, vel breviter aie Calyptra brevi- 
ter multi 
Ca alyptopogon Mitt. Theca in perichetio e foliis elongatis a 
caulinis difformibus exserta. Calyptra profunde plurifida. 
The first group contains all the species of which the fruit is 
known, and which correspond to the typical S. erythrodontus, 
together with [S. australis = S. gemmascens]}. The second group 
consists of S. mniotdes alon 
It is not quite clear hag e above remarks what was = 
precise position Mitten intended — give to Calyptopogon. The 
of the word “ gro not ‘‘genus,” and also the sitekign ia 
rred 
genus S. mnioides remains. On the other hand, Br “ei Gn 
Engler and Prantl’s Pflanzenfamilien, 214 Lief. p. 419 (1902) ) 
quotes ret as a genus, Mr. Mitten, in ans 
| as a genus.
