14. D. Banksii C. Müll.; robustissimum densi- 

 folium lutescens nitidum; folia caulina aequalia 

 Chaud rngosa) dense imbricata robustissima, late 

 ovato-lauceolata , basi constrieta, superne plus mi- 

 nus involnta, inferne margine albida, nervo tenui 

 complanato in mucronulum exeunte percursa, infra 

 nervum denticulata, e cellulis lineari-ellipticis con- 

 flatis lutescentibus, alaribus parenchymatös laxis 

 fuscescentibus planis areolata ; perichaetium longe 

 exsertum, foliis in cylindrum longum congestis , e 

 basi convolutä seusim longe cuspidatis acutis , ad 

 cuspidem denticulatis, excurrentinervibus, longius et 

 laxius reticulatis ; theca partim exserta, in pedun- 

 culo crasso levi posita, ereeta, turgido-oblonga cy- 

 lindracea, aequalis. 



Patria. Ex insula Tahiti retulit Banks. Ex Hb. 

 Thunbergiano habuit Mohr, in cujus collectione spe- 

 eimeu maneum nomine Dicrani densifolii Web. et 

 M. observavi. 



A D. calycino et rugoso foliis denticulatis jam 

 refugit; a D. obsoletinervi foliis dense imbricatis 

 appressis, habitu robustissimo thecaque aequali tur- 

 gido-oblonga jam toto coelo distat. Margine folii 

 albido ad Leucoloma accedit. 



Gen. Dicranum. 



15. D. alpicolum C. Müll.; dioieum; Dicrano 

 turfaceo simillimum , sed caulis humore foliis bre- 

 vioribus crebrioribus densius coufertis multo robu- 

 stior; folia caulina apiceni caulis veluti penicillifor- 



mi-truncatum sistentia, densissime imbricata neque 

 setaeeo-patentia, lamina multo altius ad nervum la- 

 tum producta , pericbaetialia soluni setaceo e fo- 

 liis caulinis exserta, exteriora lamina sensim, neque 

 subito in nervum protraeta instrueta; theca breviter 

 pedicellata turgescenti-ovalis brevior, minus plicata, 

 operculo breviori conico-acuminato vix obliquo in- 

 tense coccineo, neque snbulato-rostrato, humore 

 persistente, columella in operculum exserta, annulo 

 minus solubili , dentibus intense coccineis , cruribus 

 minus rugulosis.

D. turfaceum caule humore gracillimo ubique 

 setaeeo-folioso thecaque cylindraceo-oblonga subu- 

 lato-operculata sordida primo visu differt. Species 

 certe distineta, et statura luimili, colore flavescente 

 et fructibus turgide ovalibus pallidis coccineo-oper- 

 culatis pulchella. 



Gen. Leptotrichum. 

 16. L. Costaricense C. Müll. ; dioieum ; habitus

 oecupante ; pericli. basi majora laxius reticulatä; 

 theca in ped. flavo gracili substricto ereeta, elon- 

 gato-cylindracea angusta attenuata parum curvata, 

 microstoma olivacea , operculo longe subulato ru-
