Caulis 3-$ uncie altus. Folia 3-2-linearia, viridia, sicca appressa sub-

102. B. RosuLATUM (C. Müll. in Bot. Zeit. 1856, 416). Dioicum, 
humillimum, sed robustum, ex apice rosulato semel proliferum, vel ramulis 
brevissimis rosulatis innovans, basi tomentosum, apice solum foliosum. 
Folia in rosulam congesta, humore discum planum sistentia, siccitate 
erecto-conferta, robusta, flavicantia, late oblongo-ovata, acumine brevi 
reflexo coronata, e basi usque ad acumen lato-revoluta, apice serrato-den- 
tata, e cellulis incrassatis flavioribus veluti marginata, nervo valido flavo in 
cuspidem brevem excedente percursa, concava, ubique e cellulis densis 
parvis chlorophyllosis areolata; perichetialia multo minora, angustiora, e 
reliquis caulinis simillima. Theca in pedunculo flexuoso breviusculo pur- 
pureo pendula, cylindracea, longiuscula, subcernua, brunneo-badia ; peri- 
stomii dentes externi incurvi, robusti, longi, interni lati valde hiantes, ciliis 
ternis valde appendiculatis interjectis. 
Hab. Mexico, prov. Mechoacan, Cerro San Andres, Chrismar. 
Br. rosei (Americe sept. et Europz) quasi diminutivum, characteribus 
laudatis facile distinguendum. Br. mexicano quidem affine, sed caule 
semel prolifero, foliis breviter euspidatis notisque reliquis longe refugiens. 
103. B. cRANDIFOLIUM (Tayl. in Hook. Lond. Journ. vi. 336, Mnium). 
Caulis plerumque interrupte foliatus, radicellis tomentosus. Folia rosu- 
lata, late ovali-spathulata, mucrone parvo recurvo, planiuscula, patula, 
inferiora concava erecto-appressa, nervo percurrente, limbo e seriebus 
cellularum angustissimarum circiter 7 marginata, superne denticulis bre- 
vibus remotiusculis serrulata, inferne reflexa, cellulis oblongo-hexagonis, 
utriculo contracto repletis, parietibus angustis; perichztialia minora, an-
