Kaulfuss altered this name into Zindsaya (Enum. Fil. p. 218), a form adopted by some Continental 
and British authors. 
_ The very different venation which characterizes the two groups included in this genus, would be suffi- 
ciently important to raise these groups to generic value, if it were constant. I have, however, noticed 
fronds proceeding from the same rhizome in Synaphlebium pulchrum, Brack., having both forms of venation, 
and specimens of 8. Pickeringit, Brack., from Viti, accord in every respect with Brackenridge’s figures and 
descriptions, except that they want the single transverse venule uniting the venules of some of the lobes of 
the pinnule, and on account of which he refers his species to Syraphledium. Mettenius has observed the 
same inconstancy in this character in his Z. dlanda (Linnea, 1869, p. 81), from Java, the venules of which 
he describes as free, rarely anastomosing.
