MAACKIA (after Richard M.iack, Russian n:iliir;ilist 

 whoexpion-d northeastern Asia; 1S25-1SS()). Lajiniiin- 

 bsx. Trees grown out-of-<looi's for their handsome foh- 

 age and the jranioles of wliite flowers. 



Deciduous: winter-buds free, scaly: Ivs. alternate, 

 CKld-pinnate, with entii-e, opposite or nearly opposite 

 short-stidked Ifts.: fls. wliite, iiapilionaceous, in dense 

 upripht racemes, usually several in terminal panicles; 

 calyx canipanulate, .")-toothcd; stamens 10, more or less 

 connate: pod linear-<^)blong, compressed, with 1-5 seeds. 

 — Two or three species in E. Asia; usually united with 

 Cladrastis, but easily 

 distinpuished even 

 without fls. by the 

 free scaly winter-buds 

 and the opposite Ifts. ; 

 in Cladrastis the win- 

 ter-buds are naked 

 and inclosed in the 

 base of the petiole 

 and the ifts. are alter- 

 nate. 



The maackias are 

 small or medium- 

 sized trees or rarely 

 shrubs with rather 

 large pinnate foliage 

 and upright dense 

 panicles of small 

 white flowers appear- 

 ing in summer. They 

 are hardy North and 

 not particular as to 

 the soil, but prefer a 

 warm and sunny 

 position to bloom 

 well. Propagation is 

 by seeds .sown in 

 spring or by root^ 

 cuttings like cladras- 

 tis.
