 along the coast. An ornamental tree used for roadside 

 planting in soutliern California. Timber hard, strong, 

 durable; useful for railroad lies and fence posts. Said 

 to be the quickest-growing shade tree for regions ex- 

 posed to hot, bleak winds; will stand Is"^ F.

 lvs. elongated; veins very spreading: lid broadly conical, 

 acute, pale : stamens all fertile ; anthers cuneate- or 

 oblong-oval, opening by longitudinal slits : stigma not 

 dilated: fr. rather lar/re, bell-shaped, semiovate, angu- 

 lar: margin outwardly ascending. F. v. M. Eucal. 2:4.

 loH, Y&r. pdJllda, Hort.). Lvs. silvery gray: fis. red.— 

 A profuse bloomer. 



OG. Pedicels short or none : fertile seeds not winged. 



H. Fr. much contracted at the orifice, nearly globular:
