Slc. Paprika
But Al, all I did was paraphrase what was in the AOS' "An Orchidists
Glossary!" -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Books, Artwork, and Lots of Free Info! .. . . . . . . . . . . "Al" wrote in message ... Sorry Ray. You said it and I agree with it but I can not let anyone over-analize me and my back hurts from making a gravel parking lot out of my front yard and it is raining so I have time to annoy you all with my version of what you said. Also, I lay claim to "Most Anal" as well as "Most Verbose". These are my titles. At least in the two Usenet newsgroups dedicated to Orchids. Mine, mine, all mine. Anybody who wants them will eventually have to face me in the ring. And you know who you are... When dealing with *naturally occurring species* in taxonomy speak you get several levels of taxon below species rank that us hobbyists always confuse when speaking about our plants: subspecies (abr. ssp.) The rank of taxa below species but above variety; a subdivision of a species whose members have certain hereditary characteristics distinct from other populations of that species. A subspecies is added to the specific binomial and preceded by "ssp.," such as obtusifolia in the epithet Grevillea thelemanniana ssp. obtusifolia. variety (alt. varietas, abr. var.) The rank of taxa below subspecies but above forma; a plant which retains most of the characteristics of the species, but differs in some way such as flower or leaf color, size of mature plant, etc. A variety is added to the specific binomial and preceded by "var.," such as saxatilis in the epithet Juniperus communis var. saxatilis. forma (abr. f.) The rank of taxa below variety; the narrowest taxon; a plant which retains most of the characteristics of the species, but differs in some way such as flower or leaf color, size of mature plant, etc. Flower and fruit color variation are the traits most often accorded forma status. These differences are random and sporadic in the population over the species range. A forma is added to the specific binomial and preceded by "f.," such as rubra in the epithet Cornus florida f. rubra. Some of my botany textbooks elevate variety to the same level as subspecies and insert cultivar just above forma. Cultivars are man-made. They do not have to be clones. It is possible to have a cultivar level population of seed grown plants. Many vegetable seed packages are named cultivars that all produce a plant with specific characteristics, such as disease resistance of flower color, etc, even though other characteristics may vary, like plant height, branching, etc.... It is possible to have a cultivar of a variety. An example would be Cornus florida var. rubra. This is the naturally occurring pink form of a white flowering dogwood. (Some of my books say it is not a variety but a forma because it is a random difference and appears in little clumps over the natural range of the species and so refer to it thusly: Cornus florida f. rubra.) Anyway, you can go to the garden center and buy the dark red cultivar called Cornus florida var. rubra 'Cherokee Chief' And if you are still with me, sometimes the tag just reads "Cherokee Chief" and assumes perhaps you just want to buy it and plant it and nothing more. There is a sliding range in printed literature and jargon: taxonomy through botany through horticulture through hobbyist where the above terms can mix and match to the point of semi-homogeneity. Most of use know which plant we are referring to even when we use one of these words imprecisely. On our level, the levels of hobbyist and horticulturist, we as a group almost always exchange the terms variety and cultivar. As a group... Listen to people talking at your next society meeting and you'll see it is even worse than that. I hear people use the word species when talking about a grex and it makes me shudder and foam and fall down while everybody else just keeps talking like there is nothing wrong with this picture. ("What's wrong with him? Isn't that what mad cow disease looks like?") Al One more time with feeling: "The earth is a *sphere*. It is the *universe* that's flat!" "Ray" wrote in message ... My understanding is that a "variety" is a natural, or should I say "botanical" plant which shows minor characteristics that make it differ from the typical form. A horticultural- or cultivated variety (cultivar) is simply a specific plant - and it's meditatively (divisions) or meristmatically (clones) propagations - in cultivation. So... Doritis pulcherrima v. chumpornensis is a variety of Doritis pulcherrima, while Doritis pulcherrima v. chumpornensis 'Damn that's Ugly' is a cultivar of Doritis pulcherrima v. chumpornensis. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Books, Artwork, and Lots of Free Info! . . . . . . . . . . .

True Spice is NOT a variety, but a cultivar, so should be labeled as Slc. Paprika 'True Spice' Because I share your proclivity, Ray, I must ask the difference between a variety and a cultivar.
