Ceratopteris thalictroides is a fern species belonging to the genus Ceratopteris, one of only two genera of the subfamily Parkerioideae of the family Pteridaceae.[2]
Ceratopteris thalictroides is commonly known as water sprite, Indian fern, water fern, oriental waterfern, and water hornfern. In the Philippines, it is called pakung-sungay (literally 'antler fern' or 'horn fern').[3][4]
Ceratopteris thalictroides is widespread across tropical regions.[4][5]
Rooted in mud, Ceratopteris thalictroides plants vary in size and appearance. The stipes of mature plants are 3-15 mm in diameter, spongy, and air-filled with 4–60 centimeters (1.6–23.6 in) long including its stipe.
Pale green, brown when matured, fertile fronds are 15–100 centimeters (5.9–39.4 in) or more, including the stipe, to 40 centimeters (16 in) long. Proliferous or dormant buds with their overlapping dark scales present in the axils of fertile pinnae are winged. Pinnae are deeply incised with segments 2-15 mm x 10-30 mm and the fertile segments 1-2 mm x 10-80 mm.[6]
In the north type and the third type, the count of chromosomes is 2n=126 while in the south type its 2n=154, making it separate from species.[7]
Ceratopteris thalictroides is often found near stagnant water or in still pockets along slow flowing rivers in swampy areas, swamp forests, sago swamps, marshes, natural and man-made ponds. The plant thrives in full sun to moderate shade, from sea level to 1,300 meters (4,300 ft) in elevation, but mostly less than 500 meters (1,600 ft) in elevation. Ceratopteris t. is often massed on or around logs or other floating vegetation. The plant was once recorded in a fresh-water mangrove (Sonneratia) growing among the finger-like pneumatophores. In some areas, Ceratopteris exhibits a degree of seasonality, reaching maturity and shedding spores during the dry season; plants have lost nearly all sterile fronds by this stage.[6] The species has been reported to functionally be an annual, repopulating from spores the next season, but it is clearly of indefinite lifespan in cultivation.
Fronds are cooked and eaten as a vegetable in Madagascar,[4] New Guinea, and Vietnam,[8] and raw as a salad in Micronesia.. It has been used similarly to watercress.[4] In Malaysia and Japan, uncurled fronds have been used in salads.[4] However, the plant is believed to contain carcinogenic chemicals.
Ceratopteris t. is widely used as an aquarium plant,[4] and is prized for its versatility, being used both as a floating plant and a plant that can be rooted in the substrate.[9]
The plant can be used as manure for rice.[4]
Ceratopteris t. is used medicinally as a poultice for dermatological issues in Malaysia and the Philippines.[4] In China, it's applied to wounds to stop bleeding.[4]
In the Sepik region of New Guinea, fronds are used as a personal decoration.
It grows best in soil with a pH reading of 5-9 and in very high amounts of light. It usually grows quickly.
Ceratopteris t. can benefit (like all aquatic plants) from the addition of CO2. The plant's reproductive technique is similar to other ferns. Small adventitious plantlets are grown on the mother plant and are then released when ready.
It can provide useful shade to shyer fish and small fry. The dense roots are said to take nutrients out of the water, helping to prevent the growth of algae.

ミズワラビ(水蕨、学名:Ceratopteris thalictroides)は、シダ植物門ホウライシダ科に属するシダである。分類によってはミズワラビ科(Ceratopteridaceae)とする場合もある。シダとしては珍しい水草で、水中、あるいは湿地に生える。熱帯地方に広く分布し、日本では本州中部以南に分布する。水田によく生えたが、現在では見ることが少ない。
熱帯では多年生であるが、日本の本州では一年草として、夏に胞子をつけると枯れてしまう生活をしている場所もある。
根茎はごく短い。葉は栄養葉と胞子葉の二型に分化する。栄養葉は二回ないし三回羽状複葉で、小葉は丸みを帯びた三角形だが、葉全体が黄緑色で柔らかく、主軸は多肉質で一般的なシダの葉とはかなり印象が異なる。水中ではさらに葉が薄くなる。胞子葉は小葉が厚みのある線形になっている。大きさは40cmにも達するが、寒冷な地域では小型化する。ほとんど葉が分かれないものもある。
葉の先端から新芽が出て新しい株を生じる場合もある。熱帯魚の水槽内では、沈水性の水草として育てる場合が多いが、水面に葉を浮かべ、水中に根をぶら下げた浮草の形でも育つ。水中では胞子葉はつかない。
よく育つ地域では葉を食用にする。日本でも用いられたようだが、現在では除草剤のためか、他の多くの水田雑草と共に姿を消している場所が多く、食用されるほどに手にはいらない。
より多く見かけるのは熱帯魚の水槽の中である。熱帯魚用の水草としてよく販売されており、ウォータースプライト(Water Sprite)の名で流通している。あるいは水面に浮かせてその根を小魚の産卵場所に使う場合もある。より葉のきめの細かいタイプがベトナム産とされる。
