` :Thanx for the note. Very often editors change my work without explanation. Right now I am dealing with another page for which an editor simply reversed work I spent at least half an hour on. No word of explanation. As for the lists, numbering the species has the advantage of showing you unambiguously how many species there are in the genus. I have seen many pages which begin ``This is a genus of 30-40 species`` followed by a list of 53, or whatever. The estimates are frequently way off the mark and subject to change.  `
