Fissidens Garberi. Planta minutula gregaria obliquata corticola. 

 Folia 4-8 juga, leniter decurva, subelongato-oblonga, superiora quad- 

 ruplo longiora quam lata, auricula medium circa folium attingente, ala 

 dorsali instructa, lata, versus basin sensim angustata ; lamina verticalis 

 parte folii auriculata paululum latior, apice mutica, rarius breviter 

 acuminata, margine papillis in quacunque cellula marginali binatis 

 miimtissime crenulata, foliorum vaginulaa circumsitorum marginibus 

 auriculae e medio ad basin limbo e cellulis majusculis hexagono-rec- 

 tangulis bi-triseriatis instructis ; rete totius folii caeterum minutum 

 hexagono-rotundatum distinctum. 



Flos terminalis bisexualis. 



Capsula in pedicello assurgente longitudinem planta? sequante erecta 

 vel suberecta ovalis, pallide fuscescens, ore rubro mollis ; peristomii 

 perfect! dentes e basi integra dense trabeculata rufa bicrures, cruribus 

 lutescentibus ; operculum magnum rostratum. 



Hab. On tbe bark of trees, Florida (Garber). 



The plants are mostly simple, rarely dichotomous. This species 

 in the shape of its leaves resembles F. obtusifolius, Wils., but it is 

 smaller, the capsule narrower, the operculum beaked, and the areola- 

 tion rather quadrate than angular-rounded. No. 19 of Wright's 

 second collection of Cuban Mosses in Sullivant's Herbarium includes 

 many specimens (which had been examined and figured, but not 

 named) that correspond with this species, though varying in size, 

 and found on sticks, bark, and stones, as well as on the ground. As 

 other Cuban mosses occur in Florida, it is not remarkable that this 

 species also should have been collected in both localities. 



Fissidens Floridanus. Planta semiuncialis et subuncialis e basi 

 parce ramosa, inferne fusca, superne laste viridis. 



Folia e caulis basi ascendendo majora, dense conferta, superiora 

 lineam fere longa cultriformia, auricula sat longe supra medium pro- 

 ducta, apice subtiliter suberoso-denticulata, caeterum integra, limbo lati- 

 usculo pallido circumducta; costa sat valida paulum sub apice evanida; 

 reticulo minuto, hexagono, in lamina verticali basi et limbo exceptis 

 angustiore et minus distincto quam in auriculas alis, lamina dorsali ad 

 folii basin subito fere abrupta, sicca cirrhato-incurva. 



Flores monoici ; mascidi in ramulis lateralibus longiusculis termi- 

 nales ; feminei axillares ad medium caulem dispositi. 



Fructus in ramulo perichostiali perbrevi basi radicante ex eodem 

 caule solitarius, rarius binatus ; folia perichaitialia caulinis pallidiora 

 laxius texta, auricula latiore dorso usque ad medium anguste alata,
