John, Thank you for that concise clarification. On a related note, I have long wondered if there is any provision (from botanical or horticultural codes) for validly published names that are synonymized in the scientific literature yet represent 'taxa' that retain recognizable characteristics useful in horticulture. Some nurserymen will use these names parentheically, after the accepted "mother name", but is there a better way? The basis for such distinctiveness (in the eyes of some) can be natural- clones that stand out as different, or sampling from slightly distinct wild populations- or from goings on in the garden. Whatever the case they were conceived under nomenclatural rules and have proper published descriptions, type(s), etc. These taxa, if they are that, end up in a sort of no-man's land but of course they may be resurrected later in the scientific literature after further study.
