Notes
Doodia caudata is an erect tufted fern. The species is strictly riparian, occurring amongst boulders and along the shaded banks of stream and creeks. Recruitment may be from spores or horizontal runners. The following description is adapted from Duncan & Isaac (1986). Doodia caudata produces a short rhizome covered with long, light brown scales and persistent stipe bases. Fronds are clustered), spreading, membranous and dimorphic with short barren fronds (10 to 25 cm long and longer, erect, harsher fertile fronds (15 to 40 cm long). The stipe is short, pale but dark towards base and smooth. Scales are scattered, sessile, light brown and narrow. The lamina is mid-green, pinnate with pinnae in the lower half attached by midribs only and clearly separate and in upper part sessile with wide decurrent bases and close-set. The rachis is pale, often with short hairs and a few linear scales. The pinnae in the lower part of frond are stalked, small, broadly oblong with rounded tips and often with strongly lobed bases. The others are much longer than broad and have margins thickened with strongly curved teeth. The pinnae on fertile fronds are very narrow. Veins are well separated with a single row of narrow areoles on each side of midvein. The sori are narrowly oblong, each longer than 1.5 mm, in a single row on each side of midvein and close to it and are often confluent. The indusium is membranous, with small hairs
