Interesting publication, but I have one remark. It may not be a big mistake, and some may consider it a trifle, but as someone who has been passionately involved with this group of plants for many years, I will write this: rather not elaters; it should be correct - hapters, i.e. dead tape-like outgrowths of the spore wall in horsetails, reacting to changes in air humidity; they are a product of the tapetum (a layer surrounding the spore-forming tissue in the organs of some plants, involved in the process of nourishing the tissue and developing spores, as well as pollen grains); in dry air they unwind, and in humid air they twist around the spore, facilitating the dispersal of spores. Elaters usually contain living cells or simply are them - hapters, on the other hand, are completely dead / warm regards, R. J. Walkowiak.
