The D'Entrecasteaux Channell reminded JDH of the Kyles of Bute, but surrounded by gum trees, Asters & Leucopogon richei & long cutting grass. The plants on the Huon are more alpine with tropical vegetation in deep gullies. He describes some of the ferns, which incl: Allantodia australis, Polypodium vespertilionis, Pittosporum bicolor, Anopterus glandulosus & Sassafras. Also describes some beautiful, very large tree ferns giving dimensions & describing the character of their growth in the valleys. Tree ferns are covered with Psilotum triquetrum, Asplenium laxum, Polypodium grammitidis & Grammitis australis. Mosses in the valleys abound: Hookeria pennata, H. quadrifaria, Hypnum cochleariformis & a new Anomodon. Mentions an island in the mouth of the Huon made completely of fossil shells in sandstone, & on which some Asplenium species grow. Letter also includes a coloured illustration of a new species of Hookeria. The Hookeria was found growing on Dicksonia arborea on the Banks of the Huon River opposite Port Cygnet.
