Piggott, A.G., 1988.
Ferns of Malaysia in colour.
Kuala Lumpur: Tropical Press.
A photographic guide intended as a companion to 'Flora of Malaya II - Ferns' by Holttum, R.E. (1968). It lacks a key and has too much empty space on the pages, but the colour photographs, showing habit, fronds and sori are very high quality.
