Although taxonomists continue to debate the status of hosta species (it's part of their job afterall), W. George Schmidt in his 1991 classic, The Genus Hosta decided that there were 43 species. Since that time, he changed his mind on Hosta sieboldiana in 2010 and now he and The American Hosta Society call it a cultivar, H. 'Sieboldiana'. Listed below are the hosta species as we know them today...at least for now.
