Crataegus × lavallei, sometimes known as hybrid cockspurthorn[1] or Lavallée's hawthorn, is a hybrid that arose between cultivated specimens of two species in the genus Crataegus (Hawthorn).
The female parent was C. mexicana (sometimes mistakenly called C. pubescens), and the male parent is thought to be C. calpodendron [2] (which is sometimes mistakenly called C. crus-galli).[2]
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'.
Crataegus × 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.[3]
