 ACACIA NABONNANDI 

 Nabonnand's Acacia 



Garden Hybrid 



Family Mimosacka^ Mimosa Family 



This acacia is a garden hybrid, so I am informed by Mr. Louis 

 Dupuy, from whom the plant in the New York Botanical Garden 

 was secured, and was produced by crossing Acacia dealbata and 

 A. decurrens: I was also informed by him that it originated on the 

 littoral of the Mediterranean. M. Nabonnand, for whom the 

 plant was named, was a noted rosarian who produced many new 

 roses; he died in January, 1903, in his seventy-sixth year. This 

 hybrid requires the treatment accorded to plants in a cool green- 

 house. The specimen in the collection of the New York Botanical 

 Garden, from which the illustration was prepared, is in the central 

 display house at range 2. 



Nabonnand's acacia is a shrub, open and rather lanky in habit, 

 the branches usually more or less hairy. The bipinnate leaves are 

 up to five inches long and four inches broad, and have commonly 

 from five to seven pairs of pinnae, the larger one and a half to two 

 inches long and a half to three-quarters of an inch broad, the 

 rachis commonly more or less hairy. The pinnae have from fifteen 

 to thirty pairs of glabrous leaflets, at nearly a right angle to the 

 rachis, a quarter to three eighths of an inch long; they are linear, 

 falcate, and obtuse or acutish and apiculate at the apex. The 

 bright yellow flower-heads are three sixteenths to a quarter of an 

 inch in diameter; these are on short stalks about an eighth of an 

 inch long and are arranged in rather loose ascending racemes, two 

 and a half to four inches long, which arise from the axils of the 

 upper leaves. The pod is about two inches long and nearly three 

 eighths of an inch wide, and is somewhat curved, having the seeds 

 placed longitudinally.
