Cephalosia spiniflora n. sp. 
Heteroica! — Caespites olivaceo-virides vel fuscescentes 
formans plus minus densos intricatos in terra turfosa, rarius supra 
Sphagna vel lignum putridum. Caules I—2 cm longi, stoloniferi. 
Folia dissita vel contigua, oblique rotunda vel paullum oblonga, 
dorso late decurrentia, sinu obtuso sed haud lato ad 
medium fere fissa, laciniis subinaequalibus porrectis vel parum 
conniventibus, basi 4-6 cellulas latis, acutis, acumine 2-3 
cellulas longo.. Amphigastria in ramis sterilibus nulla. Cellulae 
rotundo-hexagonae, circacircum aequaliter incrassatae, 25—30 u, 
basales majores. 
Androecia longissima, dense spiciformia interdum atte- 
nuata vel vegetative excrescentia, saepe autem penicillatim dilatata 
imo inflorescentia @ terminata. Folia perigmialia monandra, 
cava, ovata ultra medium sinu acuto fissa, marginibus spinoso- 
dentata, laciniis longius cuspidatis. Amphigastria pro more 
magna, dimidium folium adaequantia, late lanceolata, + dentata. 
Gynoecium aut in ramis brevioribus aut in androeciis terminale. 
Folia et amphigastria involucralia majora pluries et irregula- 
riter ad medium vel pro more ad basin fissa, laciniis late lanceo- 
latis longo spinoso-cuspidatis (cuspide 3—4 cellulas longo), mar- 
ginibus grosse et crebre spimoso-dentatis. Cellulae 
quam in foliis sterilibus plus duplo ma TOLLES, oblongae 
(ca. 50x 30 a), circacircum optime incrassata e. Perianthia 
(omnia, a me observata) ad basin fissa, folia et amphi- 
gastrium perianthialia optime discernenda, involucralibus similia 
quoad lacinia grosse spinoso dentata necnon laciniarum 
structuram sed erecta longiora, basibus in tubum convoluta ibidemque 
e cellulis multo longioribus aedificata. Archegonia foecundata ob- 
servavi, sporogonia adhuc ignota.
