EVODIA, Rutaceae. Small aromatic trees with broad flat clus¬ 
ters of white flowers. Evodia differs from the genus Phelloden - 
dron in having its buds exposed in the axils of the leaves in¬ 
stead of being covered by the base of the petiole [6D]. 
E. Danielii. N. China, Korea. 
E. hupehensis. C. China. 
EXOCHORDA, Rosaceae. Pearl-bush. White-flowering shrubs 
that thrive in good soil and full sun. Their habit of growth is 
suited to their development as specimen rather than as border 
plants. E. Giraldii Wilsonii has the largest flowers of the 
genus [6J]. 
E. Giraldii Wilsonii. C. China (My.). 
E. Korolkowi. Turkest. (Ap.-My.). 
E. racemosa. E. China (Ap.-My.). 
E. serratifolia. Manch. and Korea (My.). 
FAGUS, Fagaceae. Beech. Gray-barked trees that make excel¬ 
lent lawn specimens. Compact in growth and attractive in fo¬ 
liage in autumn. Their surface-rooting habit makes it difficult 
for other plants to succeed in their immediate vicinity [2C, 
nursery].
