In utraque varletate atqiie in D. capillaceo Richardson, 1. c. flores monoicos, masculis 
gemmiformlbus alaiibus prope apicem ejusdem rami cum femineo gemmiformi, necnon annulum 
manifestum, in D. capillaceo, jamj am a Voitio 1. c. notatum, et dentes peristomii 16 bipartitos 
cruribus transversim connexis observavi. 
86. Barbula leucostoma, caule subsimplici, folds ovato-lanceolatis mucronulatis in- 
tegerrimis, capsula cylindracea erecta, operculo conico, peristomii dentibus obliquis apice 
tortis. 
Desc. Muscus caespitosus, semuncialis. breves, dense fobati, saspins indivisi, quan- 
doque parum ramosi. Folia mncrone brevissimo, minute areolata, marginibus anguste revolutis, 
nervo valido, siccitate adpressa et parum torta. Seta caule longior, laevis, fusca. Capsula 
laevis, nequilatera. conicum, acutum, paulo inclinans, capsula dimidio brevius, te- 
uuissime spiraliter striatum. Peristomium album, dentibus 32, filiformibus, per paria ap- 
proximatis, dimidioque inferiore trabeculis connexis, supra distinctisj apicibus parum tortis. 
Calyptra Imvis.

88. Syntrichia mucronifolia, caule ramoso, folds ovato-oblongis siccitate adpressis: 
pllo Integerrimo latitudine fold breviore, capsula cylindracea inaequilatera erecta duplo longiore 
operculo subulato-conico. 
Tortula mucronifolia, Schwaegr. suppl. 1. sect. 1. p. 136. t. 35 Wahlenb. lapp. p. 317.^ 
Desc. Muscus v. caespitosus v. aids intermistus. Caules erecti, breves, semper ramosi, 
ramis fastigiatis, dense foliati. Folia concava, marginibus integerrimls, infra medium 
leviter recurvis, minute areolatis, areolis baseos paulo laxioribus, nervo valido in pilum inte- 
gerrimum excurrente, madore erecto-patentibus, siccitate imbricatis adpressis nec contortls, 
pilo parum flexo. Seta capsula baud duplo longior, concolor, siccitate tortibs. Capsula 
saturate castanea, loevis. Operculum badium, per lentem pluries augentem spd’abter striatum, 
dinddium capsulae vix rnquans. Peristomii membrana alba, pulchre reticulata, longior cibis 
contortis. Calyptra novella tantum visa, laevis. 
Obs. Syntriclda subgenus tantum esse vldetur Barbulae (s. Tortulae), cujus dentes e mem- 
l)rana angusta ortum ducunt ; et in speciebus omnibus utriusque quas investigavi operculum 
spiraliter striatum est.
