HoMALO-LEJEUNEA. 35 
Foliola imbricata, foliis equilata plus dimidio breviora, orbiculato-reni- 
formia, undulato-retusa, insigniter convexo-recurvula, integerrima, 
basi longe attenuato-decurrentia, a media basi fere ad apicem usque 
unisulca, plerumque arhiza. Foliolum infraflorale ceteris majus, 
orbiculatum subdenticulatum tota longitudine sulcato-carinatum. 
Flores monoici et dioici: ? terminales in dichotomiis. Bracteze ramulo 
novello adnate, foliis sublongiores appressze oblique oblong acute, 
apice denticulatee, ultra $ bilobee, lobulo angusto lineari apice libero 
lanceolato; bracteola paulo brevior late spatulata, apice lato rotun- 
dato spinuloso-denticulata, inferne laxe texta. 
Perianthia magna, alte emersa, basi rufo-badia apice albida, anguste 
obovata—alia rectangulari-oblonga—planissima, decurva (ad Sca- 
pane instar) apice lato obcorcato emarginatove brevirostria, margine 
subincrassato repandulo leevissimo. 
Andrecia ramulis tenuibus julaceis, ex inferiore caule ortis, constantia ; 
bracteze pauci-plurijugze foliis 2-3-plo breviores, lobulo turgido lobo 
dimidio minore. Antheridia e reliquiis solitaria viderentur.—Plante 
unisexuales frequenter adsunt. 
Planta nostra cum descr. ‘Synopseos’ et Gottschei ‘ Mex. Leverm. 171,’ 
satis bene congruit, differt autem a speciminibus Montagneanis in hb. 
Hook. (sine loco natali) caracteribus tanti momenti ut hee ultima pro 
diversa specie fere habenda. Quum autem dubius sum, in presenti 
varietatem “apiculata” appello, a typo diversam statura duplo minore ; 
colore pallidiore; foliis planioribus, swperioribus longius apiculatis apiceque 
sepe angulato-denticulatis ; lobulo majore (=fere 4 folii) haud omnino 
tecto, apice breviter truncato; foliolis fere planis reniformi-spatulatis 
repandis; bracteola ovali apice ad + acute bifida, segmentis acuminulatis 
serrato-dentatis. 
Note.—These specimens of Montagne’s are possibly from the original 
station (“ Mt. Corcovado a cl. Guillemin lecta”), yet they differ more from 
the ‘Synopsis Hep.’ description than do my own Andine ones. In all 
the forms the lower stem-leaves are obtuse or even rotundate, the upper 
acute or apiculate, and the leaves of slender branches have a longer 
apiculus. My plant differs from the description in ‘Syn. Hep.’ chiefly in 
the obcordate, or emarginate perianth; and from Montagne’s plant by the 
broad entire (not bifid) bracteole.*
