Obs. — This genus probably consists of only a single species, 
and in affinity it may be ranked with Syngramma (not yet in 
oultivation), 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 Taenia, a tape or riband, in allusion to the 
narrow pinnae.
