amplexantia basique rotundata plicato-crispa, apice lato tamen angus- 
tissime recurvula, margine toto cellulis parvis quadratis limbata, 
anculata integerrima. 
Fl. dioici: 9 terminales, e rami dichotomia. Bracteze foliis longiores, ad 
2 usque complicato-bilobee, ad carinam rectam ala fere semicirculari 
auctze; lobi oblique lanceolati acuminulati superne sparse denticu- 
lati; lobuli duplo breviores angustioresque rhomboidei acuti; 
bracteola bracteis paulo brevior, ovalis, apice rotundato grosse 
serrata. 
Perianthia vix emersa obovata subobcordata obscure rostellata fere com- 
planata, postice parum convexa inermia, margine infra apicem ciliis 
paucis (utrinque 4-6), minutis, 3-4 c. longis, sparse obsita. 
Adyeniunt in altero cespite plant graciliores magis ramose, aliis ramis 
brevioribus julaceis, foliis lobulo turgidiore instruetis, antheridiis autem 
orbatis, anne igitur masculze?
