Macromeles tschonoskii (common names Chonosuki crab and pillar apple) is a species of flowering plant in the family Rosaceae.

[2] The specific epithet tschonoskii refers to the 19th century Japanese botanist Sugawa Tschonoski.

[3] Macromeles tschonoskii is a strong-growing deciduous tree, it has a distinctive columnar habit and is particularly noted for its autumn colouring, when the glossy mid-green leaves turn to brilliant shades of yellow, orange, purple and scarlet.

Single white flowers, tinged pink, appear in May and are followed by rounded red-flushed yellow-green crabapples.

[5] It is cultivated as an ornamental tree, for planting in gardens.
