About Adiantum atroviride Bostock
Adiantum atroviride Bostock is a small fern that has a short creeping or somewhat erect rhizome covered in dark brown to black triangular scales. Its fronds are loosely clustered and reach approximately 75 cm (30 inches) in length, with shiny black stipes and rachises. The laminae are 2- to 4-pinnate; ultimate divisions are fan-shaped (flabellate), growing up to 13 mm (0.5 inches) long, and have shallow lobes along the distal margin. Between 1 and 7 round to kidney-shaped sori form on the distal margins, most often at the base of a deep narrow sinus between lobes. This species is rare in Arnhem Land, located in the Northern Territory of Australia, but is common along Australia’s east coast, ranging from the Torres Strait south to southeastern New South Wales. It is a terrestrial fern that grows in dry to moderately dry vine forest and sclerophyll forest across a wide range of soil types. This fern is widely cultivated, and is valued for its ornamental characteristics.
