ʻO Hygrophila pinnacifida
ʻO Hygrophila pinnacifida a i ʻole Hygrophila pinnate, inoa ʻepekema ʻo Hygrophila pinnatifida. No India ka mea kanu. Ke ulu nei ia ma nā kapa o nā kahawai a me nā kahawai ma ka wāwae o ka ʻōnaehana mauna Western Ghats (Maharashtra, Goa, Karnataka, Tamil Nadu).
ʻIke ʻia mai ka waena o ke kenekulia 19. Ua hāʻawi mua ʻo Nicol Alexander Dalzell i ka mea olaola i ka genus Nomaphila. I ka makahiki 1969 ua hoʻololi ʻia ka helu ʻepekema a ua hoʻololi ʻia ka mea kanu i ka genus Hygrophila. ʻOiai ka lōʻihi o ka mōʻaukala i nā aquarium, ʻike ʻia i nā makahiki 2000 wale nō.
Hiki ke ulu i loko o ka wai a me ka lewa ma ka lepo mākū. Ma muli o nā kūlana ulu, ʻokoʻa ke ʻano o ka mea kanu.
Ma lalo o ka wai e hoʻokumu ʻia ai nā lāʻau paʻa mai nā ʻōpuʻu pili kokoke. Ke ulu nei nā ʻōpuʻu kolo mai ka mea kanu makuahine, hiki ke aʻa i ka lepo, ma luna o ka lāʻau drift a i ʻole nā pōhaku. Ma luna o kēia mau wana, hoʻomaka nā ʻōpuʻu erect, akā naʻe, i kekahi manawa e noho lōʻihi lākou i ke ʻano o nā rosettes liʻiliʻi. ʻOki ikaika ʻia ka lau lau i nā ʻāpana ʻokoʻa. ʻO ka ʻaoʻao o luna o nā lau he ʻeleʻele a ʻoliva paha me nā veins melemele māmā, ʻo ka ʻaoʻao lalo he burgundy ʻulaʻula.
Ma ke kūlana ili, hana ia i kahi kumu kū kiʻekiʻe. ʻOi aku ka pōkole a ʻoi aku ka laula o nā lau ma lalo o ka wai. ʻAʻole kūlike ka lihi o nā lau lau. Ua uhi ʻia ka mea kanu a pau me nā lauoho glandular liʻiliʻi. ʻIke ʻia nā pua violet ma ka piko o ke kumu ma nā node lau.
He maʻalahi ka ulu ʻana. ʻAʻole koi nui ʻo Hygrophila pinnate i ka ʻano mineral o ka lepo, e ʻai ana i kahi hapa nui o nā meaʻai mai ka wai me ke kōkua o nā lau, ʻaʻole ma ka ʻōnaehana kumu. ʻO nā kūlana kukui, akā i ka mālamalama mālamalama aia kahi hoʻomohala ikaika o nā wana lateral.
