This interesting fern, though seems to be common in other parts of tropical Asia, 
is known for the first time in the island Hainan, the range of distribution being thus 
extended farther north. According to Copeland, the affinity of this fern to Syngramma 
and Schizoloma is unusually clear, though both von Goebel and Bower have regarded 
it as one of the ‘“‘genera incertae sedis.”
