culo longo rubro torto cylindriea fusca, operculo oblique longe 
conieo capsulam dimidiam æquante, annulo simplici persistente, 
peristomio fere ad medium tubuloso aurantiaco. 
This pretty species comes nearest to B. cuneifolia, but differs in its- 
denticulate and more pellucid leaves, the areolation of which is more 
lax than in any other spegys of this section of Barbula that I have seen. 
STREPTOPOGON, Wils. in litt. Calyptra mitriformis, superne scabra; 
peristomium simplex, ciliiforme ; cilia 32, æquidistantia, in ciliola 
duo postice fissa, lævia, in spiram unam dextrorsum contorta, basi 
in membranam angustam coadunata; cellule operculi contortæ.

Bot. 1846, p. 50. Barbula erythrodonta, Wils. l. c. vol. v. tab. xv. 
In its mitriform, scabrous calyptra, this curious moss resembles 
some species of Tayloria, but the peristome is that of Barbula, to - 
which genus it is closely allied. 
7. Barbula elongata, Wils. in schedula; dioica, elongata parce dicho- 
tome ramosa viridis dein rufescens, foliis caulinis siccitate tortis 
madefaetis patulis e basi erecta elongatis dense reticulatis lan- 
ceolatis acuminatis apice obtusiusculis, nervo exturrente, margine 
 reflexo, apicem versus inæqualiter repando-serrulato, e cellulis 
minutis fere levibus chlorophyllosis areolatis, perichætialibus 
erectis longioribus e basi convoluta flavida, theca in pedunculo 
longo rubro cylindrica elongata curvula, operculo subulato, peri- 
stomio in membranam breviusculam circiter bis contorto. 
Flos masculus terminalis innovatione axillaris; antheridia et paraphyses 
numerosa. 2d 
This fine species is remarkable for the length of its setze, and long T. 
cylindrical capsules. The peristome is combined for about epe dae 
of its length. : : ere

8. Barbula aculeata, Wils. in schedula; dioica? elata parce ramosa 
sordide virens inferne rufescens; foliis imbricato-patentibus re-

nervo rubro acumine undulato pallido desinente, setis breviusculis 
sæpe geminatis, capsula cylindrica, peristomio basi in membransa 
angustam breviusculam unito. 
The specimens of this noble species are few and imperfect. It appears 
to be about four inches high, and the leaves large in proportion; those
