rasp fern
Noun: A type of fern belonging to the genus Doodia, characterized by having pinnate fronds (leaves) where the individual leaflets (pinnae) are sharply toothed or dentate along their edges.
The term "rasp fern" is used specifically in botany and horticulture to refer to these ferns. It is a common name applied to several species within the genus Doodia. * The rasp fern is native to parts of Australasia and the Pacific. * You can identify a rasp fern by the rough, toothed edges of its leaflets.
The name "rasp fern" is thought to refer to the rough texture of the fronds, reminiscent of a rasp (a coarse file). This characteristic is most pronounced in the young, new growth of some species, which can be a distinctive pink or red color. * The new fronds of the rasp fern emerge with a striking reddish hue before maturing to green.
