 due limits as a somewhat straggling bush, as may be

 and grace to a vase of the highly-colored flowers which 

 usually prevail at this season." The plant is reasonably 

 hardy, and can be depended upon both in the North and

 resemblance in the fruit. It belongs to an entirely 

 different order, Rutacecz, and has little in common with 

 the majestic elm. It rarely rises to more than eight feet. 

 The pteleas make up a genus of six species, only one of 

 which has a place among ornamental shrubs. P. trifoliata, 

 known as the hop tree and also as swamp dogwood, is a 

 much-branched shrub with alternate leaves usually in 

 threes, pinnate, and with oblong or ovate leaflets. If the 

 foliage is bruised or crushed it exhales a rather unpleasant 

 odor. The flowers are greenish-yellow, and have a short
