Appearance

The Dickinsia antarctica has a unique and striking appearance. It has a short and stout trunk that is covered with fibrous roots. The fronds, which can grow up to 1 meter long, are arranged in a circular fashion and give the plant an umbrella-like appearance. The fronds are pinnate, meaning they are divided into smaller leaflets that are arranged in pairs along the stem. The leaflets are dark green and have a leathery texture. The spores are produced on the undersides of the fronds and are arranged in clusters.
