Microsorum pustulatum, (kangaroo fern or hound's tongue) is a species of fern within the family Polypodiaceae. This species occurs widely in New Zealand and also in Queensland, New South Wales, Victoria and Tasmania in Australia.
Microsorum pustulatum, known Zealandia pustulata, as is a fern with bright green, and glossy fronds often found growing on trees. The name is synonymous with Zealandia pustulata, but many sources haven’t accepted the Zealandia genus. The plant belongs to the family polypodiaceae and microsoroideae subfamily, which is part of the fern family. Microsorum pustulatum is an epiphytic plant, growing on the surface of other plants. It obtains nutrients and moisture from the air, rain, and debris around it. The plant spreads through hairy rhizomes, which are often bright green and brown. The fronds grow from an erect stem, reaching up to 15″ inches long and 6″ inches wide. The glossy fronds have a leathery texture. The undersides are covered in spore capsules, allowing the plant to create new growth. The rhizomes produce fast, creeping growth, frequently covering large areas on the ground.
