3. PARKINSONIA, Linn. 



Spiny shiubs, or small trees, with bipinnate leaves; primary peti- 

 oles short, secondary elongated, abruptly pinnate, with minute leaflets. 

 Flowers yellow, in lax axillary racemes. Calyx divided nearly to base 

 into 5 equal, membranous, slightly imbricate segments. Petals 5, equal, 

 spreading. Stamens 10, free ; filaments pilose at base ; anthers uniform, 

 eUiptical. Ovary 8-15-ovulate, style filiform, recurved in bud. Pod 

 linear, contracted between the seeds, seeds albuminous. 



1. P. aculeata, Linn. ; W. & A. Prodr. 283. — Vern. Vilayati Mkar, Pb. 



Common (primary) petiole \ in. long, ending in a stout sharp spine, 

 often with lateral stipulary spines. Pinnae 6-10 in. long, 2-4 on either 

 side, clustered, flat, coriaceous, with or without minute leaflets. Eacemes 

 shorter than leaves, pods 3-6 in. long. 



Indigenoua in the West Indies and tropical America, cultivated in most 

 tropical countries, almost naturalised in India, where it is grown as a hedge- 

 plant. Has spread largely throughout the Panjab since annexation, and thrives 

 well in the more arid districts. Common in the Salt line fence in Ilarriana. 

 Fl. throughout the year. Branches lopped as fodder for goats. Wood whitish, 

 light and soft, but close-grained, polishes fairly.
