 fr. almost globular, green; nut usually oval, reticulate

 Hort. ),with narrow, piunately cut Ifts.; very effective 

 as a single specimen on the lawn ; remains usually 

 shrubby. Var. monophylla, Hort., has the Ivs. simple or 

 3-foliolate. V.ir.p^ndula, Hort., has pendulous branches. 

 Var. praepartilrlens. Hurt., is a shrubby var., producing 

 rather small, thin-shelled nuts on very young plants.
