REVIEW

Edible ferns and lycophytes in Asia
Y.M. Huang, Y.H. Chang & W.L. Chiou pg(s) 45-68
ABSTRACT
This review aims to enhance awareness of edible ferns and lycophytes in Asia. After searching the literature and relevant websites, a summary is presented of 172 taxa belonging to 61 genera and 29 families, in 14 Asian countries or regions. Dietary usage of those ferns can be classified into four main categories, i.e., vegetables, starch suppliers, beverages and snacks, of which use as a vegetable is the most frequent (144 taxa, 68%). Their leaves, especially young and tender ones, are the most frequently used organs for food. In Asia, Diplazium esculentum and Blechnopsis orientalis probably are the two most popular vegetables among ferns and lycophytes. About 16% of the taxa of edible ferns are used as starch suppliers. The massive rhizomes (stems) of tree ferns and species of the genera Coniogramme, Drynaria, Angiopteris and Pteridium, usually have abundant starch and hence are often extracted to prepare cakes, noodles, or even to produce alcohol. Beverages (ca. 12% of edible ferns) include herbal tea and liquor. Herbal tea, which is a favourite for many Asian people, is often made from a mixture of several kinds of ferns or with other vascular plants. Fern liquor may be made from starch of rhizomes or leaves. The other usages (ca. 4% of edible ferns), such as snacks and as a substitute for baking soda, are recorded from different aboriginal tribes. This review is intended to give a general overview of edible ferns in Asia as a basis for further extensive and in-depth studies.

ABSTRACT
An inventory was prepared of ferns and lycophytes at Cuniã Ecological Station, South-Western Amazonia, Brazil, between 2010 and 2015, and 54 species were recorded. Lycophytes were represented by the families Selaginellaceae (two species) and Lycopodiaceae (one species), genera Selaginella and Phlegmariurus. Fifteen families of ferns were found, with most representatives from Hymenophyllaceae (11 species), Pteridaceae (nine species) and Polypodiaceae (seven species). Twenty five genera were identified; the most species rich were Trichomanes (seven species), Adiantum (six species), Asplenium, Lindsaea and Microgramma (four species each). Seven species or subspecies are new records for the state of Rondônia: Elaphoglossum obovatum, Lindsaea lancea var. remota, Oleandra articulata, Cochlidium linearifolium, Microgramma reptans, Adiantum tuomistoanum and Meniscium arborescens. Concerning life habit, 27 terrestrial species were recorded, 23 epiphytic species and four vines. Two terrestrial species were tree ferns. Fifty two percent of the species preferred one type of habitat, 12 species were exclusively found in riparian areas, 10 in terra-firme and six along the trails. The remaining 26 species (48%) were observed in more than one type of habitat.
