Nephrolepis biserrata (Sw.) Schott

Comments

provided by eFloras
Some forms of Nephrolepis biserrata closely resemble N . multiflora in pinna shape and indument but lack the distinctively transparent-margined (i.e., bicolored) and persistent petiole scales of the latter species. Nephrolepis multiflora also has more appressed and darker-colored stem scales.

Nephrolepis biserrata (giant swordfern, 长叶肾蕨) is a tropical fern, endemic to Florida, Mexico, the West Indies, Central America, South America, Africa, and southeast Asia.

Its stipes are grayish brown and 10–50 cm × about 4 mm in size, with brownish-green, papery lamina that are 14–30 cm wide × 0.7–2 m in length, but has occasionally attained a length of twenty-seven feet (eight meters).[1] This is the largest of all the sword ferns and it often is labeled, Macho Fern, at nurseries.[2] after its aggressive growth nature when compared to ferns such as the Boston Sword Fern, Nephrolepis exaltata that is planted more commonly.

ホウビカンジュ Nephrolepis biserrata houbiknj.jpg
石灰岩から垂れる姿
沖縄県那覇市
分類 : 植物界 Plantae : シダ植物門 Pteridophyta : シダ綱 Pteridopsida : ツルシダ科 Oleandraceae : タマシダ属 Nephrolepis : ホウビカンジュ N. biserrata 学名 Nephrolepis biserrata 和名 ホウビカンジュ

ホウビカンジュ Nephrolepis biserrata は、ツルシダ科タマシダ属に属するシダ植物の一種。非常に長い葉を垂らすようにつける。名前は鳳尾貫衆で、このうち貫衆は中国名でヤブソテツの意味でシダ一般を現す。つまりの尾の様なシダの意であるという[1]

特徴[編集]

常緑性草本[2][3]。根茎は短くて、斜めか真っ直ぐに立つ。多くの細い針金のような根を出し、また走出茎を伸ばし、多くの株が寄り集まって生える。根茎と葉柄の基部には赤褐色の鱗片が密に生え、鱗片は長さ5mmで先端に向かって尾状に長くなり、縁には毛があるか不揃いになっている。

は一回羽状複葉で、立ち上がることもあるが長く下垂する。葉柄は30-60cm、葉身は長さ60-200cm、それに対して幅は20-40cm、非常に細長い形。側羽片は非常に数多く、時に70対を越える。側羽片は中軸との間に関節を持ち、線状披針形から披針形で先端はやや鎌形、長さ長さ15cm、幅1.5cm、羽片の間隔は羽片の幅よりやや狭いくらい。その基部はくさび形から円形で、耳が突出することはないか、ごくわずか。葉質は薄いが硬い。

胞子嚢群は円形で、葉縁から内側1/3程度の位置に1列に並ぶ。包膜は円腎形、径1.5mm。

 src=
羽片の先端付近

生育環境[編集]

岩や樹木の上に着生し、葉を下に垂らすようにつける。沖縄本島南部では低地の琉球石灰岩の崖の上にはえて長く垂れ下がる姿をよく見かける。

分布[編集]

日本では、トカラ列島以南の琉球列島に生育する。世界的には旧世界の熱帯域に広く分布する。

利害[編集]

園芸的に栽培されることがある。園芸品種にフルカンス 'Furcans' がある。羽片の先端が2裂し、更にその先が2-3裂するもので、鑑賞価値は高い[4]

分類[編集]

同属には30種ばかりが知られ、日本では本種とタマシダヤンバルタマシダの3種が知られる。本種は、その中で特に細長い葉を持つものである。またこれとタマシダの自然雑種がヒメホウビカンジュ、ヤンバルタマシダとの自然雑種がアイノコホウビカンジュの名で知られているが、検討が必要とのこと[5]
