Hi Brian and Julius,
This is one of those subjects that I myself am engaged in professionally,
as taxonomist of both plants in the wild and cultivated. Professional
taxonomists may consider that identifying a specific variant in nature is
useful and in that case they can make use of the classification categories
of forma (f.) or varietas (botanical variety; var.). With the growing
awareness of morphological dynamics in nature, this practice is slowing
down considerably, at least in the "western" countries. This is good
because all those var's and f's create more and more names and have a
tendency to blurr the evolutionary infraspecific dynamics of groups of
If however somebody selects a single specimen from a species in nature (or
anywhere else) because of a striking character and he multiplies it into a
group of plants that follows the prerequisites of Distinction
(distinguishable from all other named selections of the species),
Uniformity (the groups of plants to be named is uniform throughout) and
Stability (the characteristics of the group remain after several cycles of
propagation) (= DUS-norm), then the group may be considered a cultivar
(cultivated variety) and named, registered and marketed as such.
Also in the realm of cultivars and trade it is unwanted to have an
explosion of cultivar-names, so if you have just 2 or so plants with a
typical character then it is not wise to try and register it with a
There is MUCH more to this subject but that would require me to write a book.
