mor b said:im sorry tsunami, but i think u have a mistake here. im holding the "aquarium plants" by christel kasselmann and i quote : rotala sp. nanjenshan ... has been part of the regular stock of pet shops since about 1995. (it was traded under the name mayaca sellowiana for short time)
"rotala sp. nanjenshan has been imported from taiwan by aqautic plant nursery dennerle since 1993...... although they can be easily confused, rotala sp. nanjenshan can be distinguished from mayaca fluviatilis by its verticillate leaf arrangement and longer leaves"
so i guess by not having verticilllate leaves and shorter leaves - what jerime has (he took it from me) is the nanjenshan= rottala sallowiana
if u still think i have a mistake - please show me the pics of the two different plants so i can c - thanks
here is another pics from my tank
