extreme ends of the branches they are of a greenish yel-

Abele, or Silver Leaf. This tree, a variety of the poplar, 

 is highly calculated to ornament pleasure grounds, &c. It 

 attains to a large size, and is of quick growth ; but its great 

 beauty consists in its foliage, of a fine green, on the upper 

 surface, and of a perfectly white silvery hue on the under 

 side. The leaves being supported by slender petioles, are 

 easily agitated, and hang quivering, with the least brteze, 

 like the trembling aspen ; and the green and white surfaces 

 of the leaves mingled thereby, present a contrast which, at 

 .a distance, gives to the tree an appearance of being covered 

 with numerous flowers. This tree has also the advantage 

 of holding its foliage late in the season. 



Alder leaved Ck-thra, or Clethra alnifolia. This shrub 

 rises to the height of from four to six feet, and produces 

 very numerous spikes of while flowers in July and August, 

 at the extremities of the shoots, which are of delightful fra- 

 grance. Being a native of our low swamps and woods, it 

 imparts, at the season of bloom, a most agreeable sweetness 

 to the surrounding atmosphere. There are several other 

 American species. 



Bladder Senna, or Colutea. Of this there are several 

 species ; they have tine pinnated leaves, and papilionaceous 

 flowers. Those most admired are the following: 



Colutea arborescenS) or Yelloiu Flowering. This is the 

 tallest growing species ; it is a native of France and the 

 south of Europe, and is found particularly plenty about 

 Mount Vesuvius. The flowers are yellow, and are pro- 

 duced in June and July, and again in September and Octo- 

 ber. At the latter period the plant has a singular appear- 

 ance, from the circumstance of having the ripe pods of seeds 

 of the first bloom hanging on the branches, and interspersed 

 with the autumnal flowers. This, as well as the following 

 species, are of easy culture, and will grow on almost any 

 soil. , 



Colutea halefiica, or Pocock's Senna. This resembles the 

 foregoing in general appearance, but the flowers are of a 

 dark yellow, touched with red. It has the same property 

 of flowering twice in the manner of the ft regoing. 



Colutca cruenta, or Red Flowered. This is not of quite 

 as vigorous growth as the two preceding ; the foliage is si- 

 milar, but the flowers are red, spotted with yellow.
