Polystichum aristatum (Forst.) Presl.

Dictyocline Griffithii Moore. 
Dunn 37-^9, S761, simple, deeply lobed fronds: Kemp, a sterile frond with five

DicJyocUne is certainly entitled to stand as a genus, characterized even l>etter

Kwangtung Prov., China, Mattheic 33,^ 1907. 
A species of the D. mawiinutn group, recognizable by the dark color, short and 
relatively broad pinnuh;^ .^et close togetlier, short sori, and especially, having
