OBS. This genus probably consists of only a single species, 

 and in affinity it may be ranked with Syngramma (not yet in 

 cultivation), and is readily distinguished by its continual 

 linear sorus, which is formed by the confluence of numerous 

 short, oblique, sporangiferous receptacles. Specimens from 

 the Fiji Islands exhibit fructiform or ovate scattered sori, 

 which I consider to be only abnormal conditions, consequent 

 on local influences affecting development. The name is 

 derived from Tcenia, a tape or riband, in allusion, to the 

 narrow pinnae.
