Pterygoid fern
Ceratopteris pterygoid fern, inoa ʻepekema Ceratopteris pteridoides. Hoʻopuka pinepine ʻia ma lalo o ka inoa hewa ʻo Ceratopteris cornuta i loko o ka puke aquarium, ʻoiai he ʻano ʻokoʻa loa ia o ka fern. Loaʻa ia ma nā wahi a pau, e ulu ana ma nā ʻāpana tropical a me nā subtropical climatic zones o ʻAmelika ʻAmelika (ma USA ma Florida a me Louisiana), a me Asia (Kina, Vietnam, India a me Bangladesh). Ke ulu nei ia i loko o nā ʻauwaʻa a me nā kino wai paʻa, e lana ana ma luna o ka ʻilikai a ma kahakai, e aʻa ana i loko o ka lepo maʻemaʻe. ʻAʻole like me kā lākou ʻano pili, ʻaʻole hiki i ka Indian Fern a i ʻole Horned Moss ke ulu i lalo o ka wai.
Hoʻoulu ka mea kanu i nā lau lau ʻōmaʻomaʻo nui e ulu ana mai kahi kikowaena hoʻokahi - kahi rosette. He triangular nā lau ʻōpiopio, ua māhele ʻia nā lau kahiko i ʻekolu lobes. Aia ka petiole nui me kahi ʻiʻo i loko porous e hāʻawi i ka buoyancy. Ke ulu nei kahi pūnaewele paʻa o ke kau ʻana i nā aʻa liʻiliʻi mai ke kumu o ka puka, kahi kahi maikaʻi loa no ka pale ʻana i ka iʻa iʻa. Hoʻoulu hou ka fern ma o nā spores a me ka hoʻokumu ʻana i nā ʻōpuʻu hou e ulu ana ma ke kumu o nā lau kahiko. Hoʻokumu ʻia nā spores ma kahi ʻāpana i hoʻololi ʻia, e like me kahi lipine ʻōwili liʻiliʻi. I loko o kahi aquarium, ʻaʻole i hana ʻia nā lau spore-bearing.
ʻO ka Ceratopteris pterygoid, e like me ka hapa nui o nā ferns, ʻaʻole maikaʻi loa a hiki ke ulu i nā wahi āpau, inā ʻaʻole ke anuanu a me ka pōʻeleʻele (poorly lit). Hiki ke hoʻohana ʻia i nā paludariums.
