CoLuRO-LEJEUNEA. 
rente inserta, obovata, inferne suberecta canaliculato-subcomplicata, 
supra medium recurvo-patula, late concava vel subexplanata et valde 
undulata, margine pulchre sinuato-crispa rarius hice illic incisula 
lobulatave, caeterum perfecte integra et integerrima, lobulo proprio 
omnino nullo. Adcaules steriles adveniunt folia confertiora, magis 
convolutiva, sese caulemque imbricantia. Folia caulina postice brevi 
spatio dissita, nunquam contigua imbricatave; antice autem folia 
proxima superiora margine anguste obtegunt, quare incuba dicenda, 
idem ac in ceteris Jubuleis. Folia ramea capitulorumque caulinis 
similia, nisi rotundiora, seepe multoties minora; ad ramulorum in- 
sertionem tamen seepe adstat folium majus, ad spathee instar capituli 
partem involvens. Cellule inferiores majusculee elongato-hexagon 
pellucidee fere vacuz; superiores submarginalesque sensim multo 
minores wquilateree, chlorophyllose, apicales basalibus triplo brevi- 
ores; omnes subplanzee—marginales vix parum convexulee—pariete 
crassiusculo, trigonis nullis. 
Foliola ad foliorum quodque par tributa, minuta, caule abscondita, foliis 
15-20-plo minora, subquadrata, ad medium bifida, segmentis Ineequi- 
longis acutis; seepe ad squamulam minutam triangularem redacta, 
vel etiam obsoleta. 
Florescentia paroico-polygama, nempe flores in capituli ramis primariis 
terminales plerumque fceminei, ceeteri omnes autem ad innovationes 
successivas terminales paroici. Bractea lateralis pro more unica, 
magnitudine valde varia, nune folio caulino conformis, neque multo 
minor, perianthium alte superans; nunc multoties minor, ipso peri- 
anthio duplo brevior, oblongo-rotunda retusa, margine vix crispula; 
antheridia plerumque 4 (quorum una alterave interdum. sterili) 
slobosa, pallide flava, pedicello plus duplo longiore tenui (cellulis 
uniseriatis conflato) arcuato suffulta, in gremio fovens. Raro ad- 
veniunt bractee 2, altera brevior, antheridiifera tamen. Antheridia 
haud raro plura, inveni enim 7, omnia perfecta, in unice bractez 
axilla. In folii eandem bracteam proxime sequentis axilla aderant 6 
antheridia abortiva, pedicello cellulis 2 vel 3 angustis, cellula magna 
elobosa terminato constantia. Bractea postica (sive bracteola), 
bracted laterali saltem duplo minor, tenuis, cuneato-ligulata, apice 
valde inzequaliter bifida vel solum hine angulato-unidentata, con- 
voluta, pistillidium solitarium breviusculum amplectens. Bractea 
lateralis primum convoluta, bracteolam cin perianthio rudimentario 
pistillidioque involvens; tum, florescenti& confecta, plus minus 
patens. Sub flore mere fcemineo, ceeteris floribus majore, axes flori- 
feras terminante, nulla bractea antheridiifera adest. 
Perianthia primum minuta, cordato-pyriformia, stylo pistillidii toto 
exserto, matura foliis caulinis subtriplo breviora, albida, clavato- 
prismatica, parum compressa, inferne obtuse 5-gona, apicem versus 
alte plicato-5-carinata, carinis apice oblique truncatis vel potius in 
cornua brevi-triangularia, arguta vel apice papilloso-2-8-denticulata, 
porrectis, rostello nullo, capsulé emergente medio apice rupta; cel- 
lulee mediocres elongato-hexagone, truncate, inferiores duplo 
longiores quam late. Calyptra paulo brevior, pyriformis, basi 
angustata quasi-stipitata, tenuis, cellulis unistratis laxis rhomboideis 
rectangularibusve conflata, demum apice irregulariter rupta. Capsula 
in pedicello nodoso-10-articulato pellucido exserta, oblongo-globosa, 
sporis repleta nigra, evacuata albida, vix ultra medium 4-valvis ; 
valvul lanceolate, e stratis cellularum duobus tenuissimis pellucidis
