A review of the genus Stenochlaena (Blechnaceae, subfamily Stenochlaenoideae)

T. Carrick Chambers


Stenochlaena is a small but widespread genus confined to the tropics and subtropics of the Old World. A key to the species, updated descriptions, distribution-maps, and detailed drawings are provided. Also included is a key to assist in separating several genera that are most often confused with Stenochlaena. There is morphological evidence suggesting that hybrids may exist between several species in Malesia.Although primarily a rainforest genus, the distribution patterns of the various species of Stenochlaena appear closely related to ecological requirements; the hemiepiphytic members of the genus are most frequently present along forest margins in relatively high light conditions with access to a moist soil or an aquatic environment but not necessarily to perpetually humid atmospheric conditions.
