Cyclosorus interruptus ( Inglês )

fornecido por wikipedia EN

Cyclosorus interruptus, the Hottentot fern[1] or swamp shield-fern, is a fern in the family Thelypteridaceae. It is native to the tropics and subtropics in many parts of the world.[2] In the New World, it is found from Mexico to Argentina, and in the Antilles.[3] In the Old World, it is found in India, China, Malaysia, Sri Lanka[4] and South Africa. It is also found in Australia, New Zealand, Hawaii and other islands in the Pacific Ocean. The various populations differ with respect to genetic cytotypes, glands, pubescence, and frond size.[3] Its habitat is the vicinity of freshwater swamps and it may reach 1 m (3 ft 3 in) in height.

History

Detail of a pinna

In 1770 during the first voyage of James Cook, it was collected by Joseph Banks and Daniel Solander not far from Botany Bay.[5] Despite urbanization, it still occurs in a park in the Sydney bayside suburb of Monterey. The specific epithet interruptus is from the Latin, and refers to the sori.[6] The sori are in zig-zag rows or a v-shaped series along the frond margins, and are protected by a hairy, round or kidney shaped indusium.[7]

This plant appeared first appeared in the scientific literature as Pteris interrupta in 1794, published by the German taxonomist Carl Ludwig Willdenow. In 1810, it also appeared in the Prodromus Florae Novae Hollandiae as Nephrodium propinquum, authored by the prolific Scottish botanist Robert Brown. However, this plant has undergone considerable review, name changes, and taxonomic debate.[8]

Cultivation

C. interruptus is likely to be a useful landscape plant if kept damp and in gardens free of frost.[9] There are reports that the rhizome is edible.[6]

Uses as herbal medicine

C. interruptus is used in herbal medicine for sores, liver diseases, gonorrhea, cough, and malaria.[10]

テツホシダ Cyclosorus interruptus (5187997370).jpg
テツホシダ
分類 : 植物界 Plantae : シダ植物門 Pteridophyta : シダ綱 Pteridopsida : ウラボシ目 Polypodiales : ヒメシダ科 Thelypteridaceae : Cyclosorus : テツホシダ C. interruptus 学名 Cyclosorus interruptus

テツホシダ Cyclosorus interruptusは、ヒメシダ科シダ植物の1つ。湿地に生え、密集した群落を作る。熱帯域のもので、日本本土ではごく珍しいが、それ以南では普通に見られる。

特徴[編集]

夏緑性の草本[1]。根茎は地下を長く横に這い、径4-6mmで黒っぽく、先端部にはまばらに鱗片がある。葉は5-10mmの間隔で出て、葉柄には艶がある[2]。葉柄は長さ20-40(-80)cm、褐色で基部は黒くて鱗片があるが、それより上はほとんど無毛。鱗片は三角形に近い長楕円形で、長さ3mm、幅1.5mm、膜質で縁はほぼ滑らかながら僅かに毛がある。葉身は1回羽状複葉で長さ0-50cm、幅10-20cm、全体としては広披針形で、つまり最下の羽片が最大ではない。また先端は尖らない。個々の羽片は線状披針形で先端は尖り、基部は丸くなっているかくさび形で、時に短い柄があって長さ15cm、幅1.5cmに達する。先端の5-7cmは1つに繋がって単一の頂羽片のようになる[3]。葉質は柔らかい革質で深緑色、縁は羽軸の側へ1/3ないし1/4程度切れ込んでいる。葉の軸上に単細胞の毛があるが、裏面は無毛。列片には5-8の側脈があり、そのもっとも基部のものは対面の側脈と結びついて網を作る。胞子嚢群は円形から長楕円形で、列片の辺縁に近い位置に着き、成熟すると隣のものとくっついて区別出来なくなる場合がある。包膜は円腎形で柔らかく、径0.4mmで縁に毛がある。

分布と生育環境[編集]

日本では本州南部の静岡県福井県島根県紀伊半島に、四国の東南部、それに九州琉球列島に見られる。国外では世界中の熱帯から亜熱帯域に広く分布する[4]。九州以北での分布はごく限られている[5]が、琉球列島ではごく普通。大東島では内陸湿地の植物群落にテツホシダ群落が成立している[6]

低地にある日向の湿地に生え、しばしば大きな群落を作る[7]

類似種など[編集]

本種はヒメシダ属のものとされて、Thelypteris interruptaの学名が長らく用いられた。この属のものではホシダ T. acuminata も日向に生え、葉の形なども似ているが、本種の葉がやや厚手の革質であるのに対し、薄い紙質である。また本種が水浸しの場所に生えるのに対して、この種はより乾燥した場所に出現する。ケホシダ T. parasitica やイヌケホシダ T. dentata も琉球列島などでは一緒に見かけるが、これらは頂羽片が明確でなく、また葉面に毛がある。それに、これらも水浸しの場所には生えない。

なお、日本産の本種は羽軸に毛があるので、これを種内の変種と見る説もあるが、確定はしていない模様[8]

利害と保護の状態[編集]

特に利害はない。ただし、本種は日本本土では稀少なので、学術的に重要なものとされている。環境省のレッドッリストにも取り上げられていないが、鹿児島県より北の各県で指定されている[9]のもこれを反映している。例えば和歌山県にある友ヶ島の蛇ヶ池の湿地植物群落は県指定の天然記念物となっているが、その理由の1つに本種の生育することが挙げられている[10]
