The vast majority, then, of cultivar-names are vernacular or "fancy" names like 'Winston Churchill.' How should the full name of a cultivar be written? The complete and technically correct form, including the Latin name of the species from which the cultivar has been derived, is illustrated in the following example: _Sedum spectabile_ Boreau, cv. 'Brilliant,' but I hasten to add that this lengthy designation is for use only on full-dress occasions! In the example, _Sedum_ is the name of the genus, _spectabile_ the name of the species (technically called the "specific epithet"), Boreau the name of the man who first described the species under that name (technically called "the authority" for the name), cv. the abbreviation of cultivar, and 'Brilliant' the cultivar-name for the particular cultivar concerned. It should be noted (1) that the generic name and specific epithet are printed in italics, (2) that the cultivar-name begins with a capital letter, is printed in ordinary Roman type, and is enclosed in _single_ quotation marks, and (3) that there is no "authority" after the cultivar-name. These three points are important, and apply to the writing of all names of cultivars. If we wish to cut down this rather formidable string of words for every-day use, the authority can be omitted in all except very technical writing. Secondly, the abbreviation cv. can normally be left out, as the vernacular form, single quotes, and Roman type of 'Brilliant' indicate quite clearly that it is a cultivar-name, and not the name of a wild variety. In this shortened form, therefore, the name would read simply: _Sedum spectabile_ 'Brilliant' and this is the normal method of writing the names of cultivars. There are, however, two additional refinements that should be mentioned--apart from the special case of cultivars derived from hybrids, which I will deal with later. The first concerns those Latin cultivar-names which are left over from the past. These should be printed in Roman type and enclosed in single quotes to distinguish them from Latin varietal names; thus one would write _Thuja orientalis_ 'elegantissima,' where 'elegantissima' is a cultivar-name, but _Aesculus octandra_ var. _vestita_, where _vestita_ is the name of a wild variety. The second point refers to the omission of any authority after a cultivar-name. Many cultivars are first described in reports of trials, in catalogues, and other anonymous publications; this makes the quoting of an authority impractical, but there is provision in the Code for writing the raiser's or introducer's name in brackets after the cultivar-name if so desired, thus: _Weigela_ 'Avalanche' (Lemoine). 2.
