RHS Classification System
For horticultural purposes, all Narcissus cultivars are split into 13 divisions by the Royal Horticultural Society, based partly upon flower form and partly upon genetic background. Growers register new daffodil cultivars by name and color with the Royal Horticultural Society, with more than 27,000 names registered as of 2008. Registered daffodils are given a division number and colour code.

Famous quotes containing the word system:
“UG [universal grammar] may be regarded as a characterization of the genetically determined language faculty. One may think of this faculty as a ‘language acquisition device,’ an innate component of the human mind that yields a particular language through interaction with present experience, a device that converts experience into a system of knowledge attained: knowledge of one or another language.”
—Noam Chomsky (b. 1928)
