ARBORETUM ET FRUTICETUM BRITANNICUM. 



Group iv. Pentandrce Borrer. 

 Trees having Flowers with 3 5 Stamens. Prin. sp. 16, 17, and 18. 



Stamens in a flower more than 3, in most instances 5. Ovary glabrous. 

 The plants trees of moderate size. Leaves large, glossy, fragrant, serrated, 

 and having glands in the serratures, from which a resin exudes. Stamens 

 in each catkin so numerous and long, as to render the flowers, which, too, 

 are in perfection at the same time as the foliage, quite handsome, and the 

 trees, in this condition, more ornamental than those of anv other group.

Spec. Char., fyc. Leaves ovate, pointed, crenate, glandular, glabrous. Foot- 

 stalks glandular at the summit. Stamens 5 or more, hairy at the base.

 Wob.} An upright tree. Britain, on the banks 

 of rivers and in watery places. Height 18 ft. to 20ft. 

 Flowers yellow ; June. 



The flowers are remarkably fragrant, as are the 

 leaves, especially when bruised : the fragrance, which 

 is similar to that of the sweet bay (jLaurus nobilis), 

 but less powerful, is exuded from the resinous crena- 

 tures of the leaves, and from the barren catkins. It is 

 one of the most desirable species of the genus for 

 planting in pleasure-grounds, on account of the fine 

 display made by the blossoms, their profusion, their 

 abundant fragrance, the smooth, shining, rich deep green 

 of the leaves, and the comparatively slow growth and 

 compact habit of the tree. 1438 - s - p*>t&ndra.

as a native of Britain, arose from a mistake of his. (See Borrer in Comp. to
