THYSANOßOTRYA, v.A.v.R. 



Sori definiti, ad segmentes fertiles valde contractes dorsales, ad venas 

 longitudinales (vel cristas laterales) utrinque latere costae costulaeve solitarias, 

 seriati. Receptaculum elevatum. Capsulae annulo (annuli Cyathearum more) 

 obliquo completoque. Indusium nullum/ 



Rhizoma ad truncos arborum scandens. Fasciculi vasorum stipitum 

 probabiliter (rachidum certe) plures, teretes, in orbiculo positi. Frondes 

 pinnatim divisae, dimorphae. 



The true systematical place of the genus is uncertain because of incom- 

 plete material. The generic name is given in view of the fringe-like sori 

 which, looked at superficially, are in shape intermediate between those of 

 THYSANOsoria and PolyBOTRYA 



Thysanobotrya arfakensis (Gepp), v.A.v.R., this Bull., tab. X; 

 Polybotrya arfakensis, Gepp, in Qibbs, Contrib., 71. 



Receptacle orbicular, laterally flattened (nummuliform), perpendicular 

 to the costula, apparently marginal because of the much incurved or 

 inflexed lamina of the ultimate laciniae.
