Sorbus esserteauana published the epithet was written as "esserteauiana". However, according to ICBN (Vienna Code) Art. 60.11 and 60C.1(c), the connecting vowel "-i-" in it is unnecessary and thus must be deleted. Sorbus esserteauana Sorbus esserteauana, commonly known as Esserteau's rowan, is a species of rowan. It is a small tree, typically tall growing in mountain thickets and cliffs. It is an endemic species to China, being only found in western Sichuan. It has small white flowers and small red berries that are actually a pome fruit. Unlike all other species of "Sorbus", the fruit are hard and inedible to humans, but
Arran whitebeams between "S. arranensis" and the mountain ash ("S. aucuparia"). The "Sorbus" group are apomictic, producing viable seed without the need for pollination and fertilisation. Each time this hybrid cross occurs a new clone is effectively produced. Smart showed by using physical characteristics that the species were separate and not a result of random variation. Some overlap does however occur and this suggests that some hybridising may occur between the two species. A number of other "Sorbus" species have been produced in this way, such as the Devon whitebeam, the Bristol whitebeam, the Cheddar whitebeam, Irish whitebeam, Lancaster whitebeam, etc. All
