01Description
It grows 5-30 mm (0.2-1.2 in) tall, with a 5-10 mm (0.2-0.4 in) diameter. Leaf stalks branch off the main stem, which also features a few "small black scales". The stalks themselves are "black and shiny", around 2-5 cm (0.8-2.0 in) long. Branching off from the stalks, the fronds of the fern are 8-30 cm (3.1-11.8 in) tall by 0.5-3 cm (0.2-1.2 in) broad.
