 respects, but not as valuable a tree. 



41. E. viminalis. 



MANNA GUM. 



Identification : Leaz?es — Of young plant and suckers, 

 stemless, slender, pointed, with broad bases and placed opposite 

 on the stem. Narrower on older trees. Flowers and Fruit — 

 Flowers of medium size on slender stalks, variable in number. 

 Covering of flower buds approximately cone-shaped, usually a 

 low, broad cone. Seed case top-shaped or nearly globular, 

 valves protruding. Bark — Surface of bark varies. The per- 

 sistent bark brownish in color, furrowed and rough. Bark on 

 branches usually flakes off. 



Growth : Tree may reach 300 feet in height and a diameter 

 of 15 to 30 feet. Exceeded only by E. globulus in rapidity of 

 growth. At Pasadena, in 24 years, 100 feet high, diameter 5 

 feet. Small branches usually droop. 



Wood : From light to dull brick in color. Timber less valu- 

 able than that of most eucalypts. Durability — Authorities differ 

 about its durability under ground. Uses — Useful for forest 

 cover, windbreak, shade, and fuel, though not the best fuel.

 well. Temperatures endured, 15 to 20 F. and no to 115 

 F. Soil — Shows moderate toleration for alkali.
