"For some time Tropica has been selling a plant known as “Pellia”, which has now been renamed Monosolenium tenerum. When plant names change, it usually means that botanists have discovered that they are not in fact dealing with the plant they thought they were, or, more seldom, that two botanists have independently discovered and named the same plant. In the latter situation, the first name to be announced is always the one which applies. Spelling errors are a different matter, and may be repeated so many times that the correct spelling is only discovered when someone refers to the original description. In the present case, several factors have contributed, and there are spelling mistakes in both the old and the new name.

  Monosolenium tenerum has been mistakenly known as Pellia or Pelia (with a single “l”) and the erroneous specific name has also been spelt in two different ways as endiviifolia and endiviaefolia. In addition, Monosolenium has been seen spelt with an “e” instead of the third “o” on occasions. In other words there has been a good deal of confusion, and unfortunately the matter was not entirely settled when Tropica had the plant labels printed. There will therefore be a transitional period in which plant labels will be seen with the third “o” wrongly transformed into an “e”! However, we hope that the correct name, Monosolenium tenerum, will eventually become established among growers as well as aquarium owners. The subject of erroneous names is an amusing study in its own right – and you can read the full story in the German magazine Aqua-Planta no. 3 – 2003."
