Discussion

Species ca. 30 (1 in the flora).

Eriobotrya is distinctive in Maleae; among other attributes it contains the largest plants in the subfamily with forest trees to 20 m and has pomes that do not have cores but have large seeds (J. R. Rohrer et al. 1991). Important regional revisions are by J. E. Vidal (1965) and Gu C. and S. A. Spongberg (2003c). The closest relation is Rhaphiolepis Lindley (D. Potter et al. 2007), in conformity with morphologic evidence. Eriobotrya japonica provides a delectable fruit. In addition to this species cultivated and escaped in the southern United States, E. deflexa (Hemsley) Nakai may be encountered in arboreta in the same area.

Naturalized plants of Eriobotrya japonica are only sporadically found in North America. The species is apparently native to east-central China (Gu C. and S. A. Spongberg 2003c), but it has long been cultivated and is now spontaneous in a much larger Asian area. The species is cultivated widely for its fruit in warm temperate and subtropical regions.
