Periradons. The meaning of the wnril ATcffrimio, is unknown. It is supposed Ijy nome to have oriijinated among the Frenta 

 of Illinois and liad some connection with the tremulous and playful motions of the lonff pinnated leaves of this tree. The Illi- 

 nois name, Krablt a giguiiru. sisnifies, literally, Ilomping or Frisky Maple The specific name, acurCides, is derived from 

 the Lalin arer a maple, and tlie Greek eidos. reseuihlance, and was originally applied by Mcench, from the analogy this spe- 

 cies bears to the maples. The specific ivMm:. fraxini/ulium, Is derived from the Latin fraxinus, the ash, aati folium, a leaf.

Description. 



5^^Hn Negundo fraxinifoli- 



^< n H rl um, in favourable situa- 



^ LI ((^ tions, attains a height of 



^^^^1 forty or fifty feet, with a 

 diameter of fifteen to twenty inches. The bark of 

 the, trunk is brown, the inner portion of which has 

 a disagreeable odour; and that of the young 

 branches is of a smooth, rush-like appearance, 

 interrupted only by a few buds, and is of a beautiful 

 pea-green, like the shoots of the Jasminum offici- 

 nale, but on a larger scale. The trunk ramifies at 

 a small distance above the ground, and forms a 

 loose, and wide-spreading head. The leaves are 

 opposite, and from six to fifteen inches long, accord- 

 ing to the vigour of the tree, and the moisture of 

 the soil in which it grows. Each leaf is composed 

 of two pair of leaflets, with an odd one. The leaf- 

 lets are petiolate, oval-acuminate, and sharply 

 toothed. Towards autumn, the common petiole becomes of a deep red. The 

 flowers are produced profusely, in April or May, and appear with the leaves. 

 They occur in slender pendulous racemes, are small, and of a green colour, 

 which renders them difficult to be seen, unless they be closely watched in the 

 flowering season. The racemes of fruit, that succeed the flowers, increase 

 gradually to the length of six or seven inches, and as the season advances, they 

 appear conspicuous among the foliage. 



Variety. According to Loudon, there is a variety of this species growing in 

 the arboretum of the London Horticultural Society, called Negundo f. crispnm,
