GENUS INDEX

GENUS CODE: MAGNO
GENUS SCIENTIFIC: Magnolia
GENUS AUTHORITY: L.
GENUS COMMON: Magnolia
GENUS SUMMARY: As treated here, a genus of about 130 species, trees and shrubs, of e. Asia (Himalayas and Sri Lanka to Japan and w. Malaysia) and America (e. North America to West Indies, Central America, and South America); alternate treatments in current use divide Magnolia into as many as 16 genera (of which Magnolia Linnaeus, Houpoea N.H. Xia & C.Y. Wu, Metamagnolia Sima & S.G. Lu, Paramagnolia Sima & S.G. Lu, and Yulania Spach are represented in our flora). Molecular phylogenetics show Magnolia virginiana and M. grandiflora as closely related in a New World primarily subtropical clade, M. macrophylla in a clade with its close relatives, M. fraseri and M. pyramidata together, M. acuminata as basal in a clade that is otherwise Asian (equivalent to subgenus Yulania), and M. tripetala grouped in another clade that is otherwise Asian (Azuma et al. 2001). The sections used follow Figlar & Nooteboom (2004).

PHENOLOGY: Apr-May; Jul-Oct.
HABITAT: Mesic forests, ravines.
COMMENTS: Centered in the Southern Appalachians, but avoiding higher elevations, and therefore occurring primarily around the Blue Ridge; ranging from sc. and sw. PA, s. OH, s.
