Angiopteris evecta (Marattiaceae) giant fern, king's fern, mule's-foot fern

MORE IMAGES

Angiopteris evecta is a large fern, with a "stem" (rhizome) up to 3' (1m) tall, and leaves up to 10' (3m+) long and 6' (2m) wide.  "...Angiopteris is apparently naturalizing in wet valleys on Oahu, a cause for concern." Additionally: "Mule's-foot fern [Angiopteris evecta] is naturalizing freely in the Lyon Arboretum and other local botanical gardens, apparently spreading by spores shed from cultivated plants into nearby areas of the Koolau range. Populations of naturalized plants have been found in the Maunawili area of windward Oahu as well as other localities, and this fern appears able to naturalie freely in wet valleys. It woon overtops the surrounding native and exotic vegetation, quickly spawning swarms of offspring downslope/downwind of the parent plant. For this reason we discourage continued planting of mule's-foot fern as an ornamental, and we encourage gardners to eradicate plants already growing in their yards." (Staples and Herbst. 2005. A tropical garden flora.) (Cited in this quote is also: Funk, E. 1987. Spontaneous spread of Angiopteris evecta (Marattiales) in the central Koolau Mountains, Oahu, Hawaii. Newslett. Hawaiian Bot. Soc. 26(3): 58-59.)  "[Angiopteris evecta] was introduced to Hawaii in 1927 at what is now the Harold L. Lyon Arboretum in Manoa Valley, Oahu." (Staples and Herbst. 2005. A tropical garden flora.)
