The specimen n. 2225 from Herb. Wallich among Hooker's specimens at Kew is labelled Kamaon in Hooker's band, though Roxburgh gave Amboina as its origin; another was figured by Beddome; both have small red glands on the sporangia like those from the Moluccas. No locality is indicated in Wallich's Catalogue. Philippine specimens seen are more shallowly lobed than those from Java.
