Alsophila colensoi, also known as the creeping tree fern, mountain tree fern and golden tree fern, is a species of tree fern native to New Zealand, from the southern part of the North Island south to Stewart Island. It grows in submontane to montane forest in damp areas, particularly near the tree line. The trunk is usually prostrate, but may sometimes be erect. It may reach about 1 m in height. Fronds are tripinnate and about 1.5 m long or more. The rachis and stipe are slender, pale brown and are covered with brown scales. Sori occur in two rows, one along each side of the fertile pinnule midvein, and lack indusia. Plants form a thicket with no sign of a trunk.[2]
