Perhaps it's worth rephrasing Jim's remarks by saying that the type of a taxon is often not typical of the taxon. Thus the adjective "typical" has two disparate connotations, the strict botanical sense of the word referring to the type specimen, and the ordinary, looser everyday sense that refers to what's usual for the taxon. In the eastern Asiatic flora in particular, many plants were first named from horticultural forms, as plant collectors were restricted in their travels to cities and the environs thereof. As is well known, gardeners tend to select aberrant forms, hence many type specimens are quite atypical of the species as a whole. Interesting example: Kerria japonica, first named on the basis of the double- flowered form acquired from a horticultural source. It was unassigned to any family because it is so double that the floral anatomy distinguishing families was obliterated. Only when a single flowered form was found growing wild was Kerria finally assigned to the Rosaceae. As for Lilium leichtlinii, the horticultural group nomenclature might work best: Lilium leichtlinii Leichtlinii Group (i.e. w. yellow flowers) Lilium leichtlinii Maximowiczii Group (i.e. w. orange flowers) Generally speaking, flower color is NOT considered to be a useful criterion for distinguishing formally defined botanical taxa, so even "Lilium leichtlinii var. maximowiczii" is a rather dubious use of botanical terminology. If, however, L. "maximowiczii" consistently differs from L. "leichtlinii" in anatomical details, then the use of the botanical "var." level would be appropriate. -- Rodger Whitlock Victoria, British Columbia, Canada Maritime Zone 8, a cool Mediterranean climate on beautiful Vancouver Island http://maps.google.ca/maps/…
