Yes, I know Alberto, it was published by your favorite author. : ) Note that Leptochiton is masculine (Greek; the -on ending might suggest that it's neuter but it's masculine) so the name is Leptochiton helianthus, not R's heliantha. And, for those of you who follow the text book rules for placement of the stress, the i in chiton is short, thus the stress drops back a syllable: lep-TO-chi-ton. Jim McKenney
