Bruchia brevicollis L. & J. Man. 47 (1884). 
Phascum flexuosum Sw.; Muhl. Cat. 98 (1813)? Name only. 
Muhlenberg’s Catalogue cites Swartz as the authority for this 
species, but without reference, giving the name only. Mr. J. H. 
Redfield searched, at my request, in Muhlenberg’s Herbarium for 
the specimens, but no mosses could be found in the collection. 
The specimens he sent to Schweegrichen, which were described 
and figured in the Supplement must stand as the types, as shown 
by the following description. 
“P. flexuosum Muhlenberg Catalogus Plantar. Americz Septentr. p. 98. 
“In terra nuda Pensilvaniz lectum misit beatus Muhlenberg.” 
These specimens are preserved at the Boissier Herbarium at 
Geneva, and through the kindness of M. Barbey and M. Autran 
we have been permitted to examine them. 
There are six separate plants, pasted on a sheet of paper, at 
the botton of which is written, « Phascum flexuosum Pensilv.,” and 
above is a drawing of a cucullate calyptra like the one figured in 
ig. 8. The plants bearing fruit are three in number, two of 
them nearly 5 mm. high, with stems simple, the lower leaves rudi- 
mentary, the upper crowded around the seta, reaching to the base 
of the Sporange in two of them, and to the apex ora little beyond 
it in the third, which is less mature than the others. The leaves 
are erect or slightly secund, 1.5-2 mm. long, slightly broad at 
ase, suddenly contracted into a straight or flexuose awn, rough- 
€ned on the back by the thickening of the short transverse walls 
of the Vein, serrulate at apex, ending in three longer, clear cells; 
vein thick, broad, nearly filling the whole of the awn; cells of the 
‘sal blade rhomboidal, becoming lax oblong at base, and some- 
times serrate at apex, below base of the awn. Moncecious, the an- 
antheridia in the axils of the upper leaves, near the perichetium, 
on€ or two, without paraphyses. Seta erect or slightly curved
