complicata, plicé transversa; lobulus 4-plo brevior cucullato-inflatus 
—in situ fere globosus; cellule mediocres pachydermes pellucidie 
annulo opaco cinctie. 
Fohola plus dimidio breviora imbricata reniformia basi exciso-subde- 
currentia, alia apice retusula, fere plana v. recurvo-convexula, 
solum ad ‘pilum radicelliferum externe gibba. 
Flores monoici: @ in ramo_ brevissimo terminales, innovatione pauci- 
folia suffulti. Bracteze foliis duplo breviores obovato-oblonge, 
obcordato-bilobee, segmentis rotundatis, laxe complicate, carinate, 
altera (interior) submajor, ad carinam papilloso-subalata ; bracteola 
obovato-oblonga retusula. Ramulus fertilis infra florem szepissime 
folium unicum minutum inequaliter bilobum gerit, foliclo adjecto 
minuto nullove. 
Perianthia f. caulinis subminora obovata subobcordata antice depresso- 
plana livia, postice alte convexa (e carinis duabus, inferne dissitis, 
apice conniventibus, in unam altam prelatam coalitis), margine a 
medio saltem hamato- ciliata, ciliis 4-6 ¢. longis, postice ad convexi- 
tatem supra medium ciliis dense conspersa. Calyptra paulo minor 
tenws pyriformis. 
Amenta ¢ ramulis caule inferiore insidentibus, folio caulino paulo 
longioribus, constantia; bracteze mediocres 6—7-jugze haud confertee. 
L. pogonoptera differre videtur foliis minus confertis longioribus con- 
stanter muticis; foliolis orbiculatis nec reniformibus ; perianthiis oblongis 
magis regulariter ciliatis; anne tamen specifice ?
