equatorjournal: Niels A. Douwes Dekker, Kalimantan, 1962. “Kalimantan is one of the most ideal places for the study of tropical plants. It is estimated that 1,100 varieties of fern grow there. There is something prehistoric about the gigantic ferns shown here. Ferns were actually most widespread during the carboniferous period, when coal was formed.” From “Tanah air kita: a pictorial introduction to Indonesia” by Niels A. Douwes Dekker, 1963.https://www.instagram.com/p/COGShNIAnMx/?igshid=1pyt32r7engpf -- source link
