dipteris
Dipteris is a genus of about seven species of ferns, native to tropical regions across the world, particularly Asia, with a species in northeastern Queensland in Australia. Species of dipteris grow from creeping rhizomes, and have large stalks to the sporangium and annulus. The rhizomes have bristles (or hairs) and the fronds have uniseriate hairs (having one line or series). All species of dipteris have spore-capsules that are carried on the lower surface of the broad lobed frond. The fronds can reach up to 50 cm long. Many species are found in Malaysia, Philippines, Samoa and New Guinea, growing beside Matonia.
