Crataegus × lavallei
Carrière's hawthorn, C. × carrieri has the same parentage, and is therefore a synonym, i.e. the same species. There are minor differences between Lavallée's hawthorn and Carrière's hawthorn, and the latter is appropriately considered a separate form, which is formally written as Crataegus 'Carrieri'.
C. × lavallei is an ornamental small tree with glossy dark green unlobed leaves that is used horticulturally. The cultivar 'Carrieri' has gained the Royal Horticultural Society's Award of Garden Merit.
