ACACIA 



ACACIA 



thoy are very valuable acquisitions to our Easter planta. 

 The aeaeia has two liistiiiotive ehanns: the foliage is 

 either small, simple aiul glaucous, as in .1. iirinala, or 

 mucli diviiletl, graceful and fern-like, as in .1. iiubescens. 

 All the acaeijis are among the freest-flowering of our 

 hani-woodetl plants. (.W illiam .Scott.)
