Tree, Prickly Ash^.* 



A peculiar small tree with strong, short thorns on 

 the main stem and branches, large pinnately com- 

 pound leaves and large clusters of small greenish- 

 white flowers terminating the branches. The Tooth-

 dish-green fruits are quite decorative. Date of flowering : May 25,

 India, is also frequently spontaneous. The leaves are large, doubly 

 pinnatelv-compound, and with cut leaflets ; the flowers purplish and 

 with a heavy fragrance ; fruit a light-colored berry with a ridged 

 stone containing several seeds. As a rule all of the seeds in a 

 berry do not come up the same year. A low spreading variety, called 

 the Umbrella Tree, which originated in Texas, is now very popular.
