Elatiuscula e rubro atra stratificata seepe pendula. Caules 3-6-pollicares 
tenues fragiles laxe pinnati subbipinnative intricati. 
Folia laxe imbricata late patula siccando sepius falcato-subsecunda, e 
basi biauriculato-cordata concavo-amplexante triangularia, in acumen 
subulato-setaceum flexuosum attenuata ; lobulus sub 8plo brevior 
tenuis cylindricus cauli appressus basi bifidus ; cellulee 75™™ longe, 
latitudine dimidio minores, rectangulares rhomboidezve, omnes fere 
zquales, paucissime basales subrotunde. 
Foliola plus duplo minora dissita lineari-oblonga ad 4 bifida, segmentis 
subulato-setaceis, basi perpaulo latiora subcordato - amplexantia, 
ceeterum subplana. 
Flores dioici :2 in ramo primario valde abbreviato terminales. Bractez 
confertze subappresse, intima majuscule libere bracteolaque 
bipartit, laciniis omnibus subequimagnis longe setaceo-acuminatis 
integerrimis vel supra basin posticam unidentatis. 
Perianthia immersa triquetro-fusiformia equilatera longissime rostrata 
demum apice trifida. 
“ Andreecia lateralia sessilia oblongo-rotunda ” (Tayl. 1.c.). 
Planta omnium Frullaniarum quam maxime singularis! aspectu 
Hypnum elodes potius quam ullam hepaticam referens.

Elata stratificata, procumbens, erecta vel seepe pendula, pinnata 2-3- 
pinnatave, eleganter thyoidea, rufa pallidave, raro virescens nigres- 
censve, caule determinato nec indefinite prolongato. 
Folia imbricata patula, in sicco perseepe convolutiva, concava in plerisque, 
margine toto incurvulo, in paucis planiora margine (saltem postico) 
recurvulo, semicordato-ovata-oblongave seepe abrupte apiculata, raro 
acuminata vel mutica, pro more integerrima ; lobulus cylindraceus 
cauli subcontiguus et fere semper parallelus—raro parum divergens 
—szpe evolutus ; cellule plerumque parve, pariete incrassato. 
Foliola in plerisque dimidium folium subexcedentia, ovali-rotunda (e 
margine toto recurvo ad speciem spatulata) breviter bifida, apicibus 
seepius acutis, basi decurrente szpissime utrinque auriculata crispa- 
taque ; in paucis cladocarpicis majora oblata planioraque, interdum 
subintegra. 
Flores omnium dioici: 2 utplurimum in caule vel in ramo longiusculo 
terminales, in paucis ramulo brevissimo constantes (quasi-laterales). 
Bractez 3-5-juge bilobe (complicate vel solum concave) pro more 
acuminatz, lobulis bracteolisque seepissime spinulosis laciniatisve.
