Description
Taxonomy
It was first described as + Pirocrataegus L.L.Daniel by Lucien Louis Daniel in 1915,[8][5] but this description may be a Nomen nudum.[8] It was described a second time as + Pyrocrataegus Rehder by Alfred Rehder in 1927.[1][9] The correct genus authority is unclear. Some sources credit Lucien Louis Daniel,[5] while others credit Alfred Rehder as the taxon author.[10] It is an artificial hybrid genus involving Crataegus and Pyrus.[1] Some sources treat it as an "unplaced name".[3] Its status is somewhat uncertain: Some treat it as a genus of graft-chimaera,[1][5] some as a nothogenus,[10][4] and some sources simply list it as a genus.[9][3] This intergeneric hybrid between Pyrus and Crataegus is yet to be confirmed by modern taxonomical methods.[4]
Its only species Pyrocrataegus willei L.L. Daniel[2] was described by Lucien Louis Daniel in 1915.[11]
Etymology
The generic name Pyrocrataegus combines the genera Pyrus and Crataegus.[12][5]
