Pteris tripartita Sw., J. Bot. (Schrader) 1800(2): 67 67 1801. (Syn: Litobrochia marginata (Bory) C. Presl; Litobrochia tripartita (Sw.) C. Presl; Pteris marginata Bory);
Fern of Banyumas: We need your help to identify our fern please.
This is Pteris tripartita, a kind of tropical lowish-altitude equivalent of the higher altitude P. wallichiana of the Himalayan region, but with many more anastomosing veins and areoles.
It occurs also in South India, found by Beddome and others, and rather recently mistaken for P. walllichiana.
