Crataegus Flabellata
''Crataegus flabellata'' is a species of hawthorn known by the common name fanleaf hawthorn. It is native to the northeastern United States and adjacent Canada. It is intermediate in appearance between ''C. macrosperma'' and ''C. chrysocarpa''. ''C. macrosperma'', which occurs throughout the range of ''C. flabellata'' and also in the southeastern U.S., is often misidentified as ''C. flabellata''. Varieties ''Crataegus crudelis'' Sarg. is a form of ''C. flabellata'' from Quebec that has very long thorns (up to 10 cm). The two varieties ''C. flabellata'' var. ''grayana'' ( Eggl.) E.J. Palmer and ''C. flabellata'', var. ''flabellata'' differ in that the first has 20 stamens per flower, and the latter has 10 stamens, but in other features the two varieties are variable and the features overlap. Hardy and robust, the ''grayana'' variety is commonly grown as a hedge in Sweden and Finland, where it was introduced in the 18th century by the botanist Pehr Kalm Pehr Kalm (6 M ...

Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in ) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, ''Escobaria vivipara'', is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. Definitions The term is defined in different ways by different authors. However, the International Code of Nomenclature for Cultivated Plants, while recognizing ...

Willard Webster Eggleston
Willard Webster Eggleston (March 28, 1863 in Pittsfield, Vermont – November 25, 1935 in Washington, D.C.) was an American botanist, employed by the United States Department of Agriculture Bureau of Plant Industry. He graduated from Dartmouth College in 1891 with a Bachelor of Science degree. In his work on the taxonomy of ''Crataegus'', now known to be complicated by apomixis, polyploidy Polyploidy is a condition in which the cells of an organism have more than two paired sets of ( homologous) chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two complete sets of chromosomes, one fro ..., and hybridization, he aimed to simplify, counteracting the proliferation of species names that other botanists had produced.
