Cyathea hancockii : ウィキペディア英語版 | Cyathea hancockii
''Cyathea hancockii'' is a species of tree fern native to the Ryukyu Islands, Japan, Taiwan and Hong Kong. The specific epithet ''hancockii'' commemorates William Hancock (1847-1914), who collected numerous plants in Japan, China and Southeast Asia. It grows in forest, on stream banks, and in forest margins at an elevation of about 600 m or higher. ==Description== The trunk of the ''Cyathea hancockii'' plant is either prostrate or short and erect. Fronds may be bi- or tripinnate and up to 1.5 m in length. Characteristically of this species, the lowest pinnae are usually reduced. The rachis and stipe are glossy, brown to purple-dark brown in colouration, and bear scales and hairs on the upper surface. These scales are brown, linear and have rounded bases. Sori occur in two rows, one on either side of the pinnule midvein, and lack indusia.
