Splitting hairs here for some people, but "Iinterdivisional" may or may not be the same as "intersectional", yet another irreconcilable difference between horticulture and botany. But I might point out that the information in the paper thatJoshua notes in the previous post is titled intrasectional, not intersectional. Intrasectional hybrids are crosses within a section (of lilies in this case); intersectional hybrids are crosses between sections, and would be more akin to interdivisional. Still, I would consider L. speciosum x L. nepalenses to be a much wider cross than a normal intrasectional hybrid.
