Derivations The meaning of the wordNegundo, is unknown. It is supposed by some to have originated among the Frenco. 
of Illinois and' had some connection with the tremulous and playful motions of the long pinnated leaves of this tree. The Illi- 
nois ame Erable d giguiires, signifies, literally, Romping or Frisky Maple The '.specific name , acer tides, is derived from 
the Latin acer a maple, and the Greek eidos, resemblance, and was originally applied by Mcench , from the analogy this spe- 
cies bears to the maples. The specific name, fraxinifolium, is derived from tae Latin fraxinus, the ash, and folium, a leaf.

Description. 
HE Negundo 
fraxinifoli- 
um, in favourable situa- 
tions, attains a height of 
i 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. crispwm,
