386 FRAXINUS EXCELSIOR. 
8 F. e. foliis argenteis. Silver-striped-leafleted European Ash ; F. e. ar gen- 
tea, of Loudon ; Frene ar genii, of the French, with leaflets variegated with 
white. 
9. F. e. lutea. Yellow-edged-leafleted European Ash, with the leaflets edged 
with yellow. 
10. F. e. erosa. Erose-leafleted, European Ash, with the leaflets erosely 
toothed. 
11. F. e. horizontals. Horizontal-branched European Ash; Frene horizon- 
tal, of the French, with the branches spreading horizontally. 
12. F. e. verrucosa. Warted-barked European Ash; Frene verruqueux, of the 
French, with its branches warty. 
13. F. e. verrucosa pendula. Pendulous-branched Warted-barked European 
Ash. 
14. F. e. nana. Dwarf European Ash, which seldom exceeds a yard in height. 
The leaves of this variety resemble those of the species, but the leaflets are much 
smaller and closer together. 
15. F. e. fungosa. Fungous-barked European Ash. 
16. F. e. verticillata. Whorled-leaved European Ash ; Frene d feuille verti- 
cillees, of the French. 
17. F. e. villosa nova. Villous-leajleted European Ash, a new seedling, acci- 
dentally discovered by M. Descemet, of which there are plants in the Odessa col- 
lection. 
18. F. e. heterophylla. Various-leaved European Ash ; Fraxinus heterophylla, 
of Don, Loudon, and others; Frene d une feuille, of the French; Verschieden- 
bUttrige Esche, of the Germans. The leaves of this variety are trifoliate, den- 
tately serrated, usually simple, but sometimes with three or five leaflets, three or 
four inches long, ovate, sub-cordate, or acuminate at the base and apex. The 
samara? are oblong-lanceolate, one inch in length, obtuse and emarginate at the 
apex. The branches are dotted, and the buds are black. Some botanists con- 
sider this kind as a species; but Sir T. Dick Lauder states that Mr. McNab, 
of the Edinburgh botanic garden, sowed seeds produced by the tree in that gar- 
den, supposed to have been originally planted by Southerland, and found that 
the plants had pinnated leaves; and M. Sinning, garden inspector of Poppilsdorf, 
near Bonn, sowed seeds of the common European ash, which he gathered in a 
distant forest, many of which came up with simple leaves. Nearly one thou- 
sand of these plants were transplanted, and left to become trees; when they were 
about eight feet high, nearly twenty of them were observed to have simple leaves, 
and almost as many to have only three leaflets; though occasionally they showed 
a greater number. 
19. F. e. heterophylla veriegata. Variegated Various-leaved European Ash, 
discovered in 1830, in the grounds of Captain Moore, of Eglantine, near Hillsbo- 
rough, in the county of Down, in Ireland. The variegation appeared in sum- 
mer, on the point of one of the shoots of a tree of fifteen years' growth ; and 
Captain Moore marked it, and had the portion of shoot which showed the varie- 
gated leaves taken off, and grafted the following spring. The parent tree, it is 
said, never has since shown the slightest tendency to variegation, but the grafted 
plants continue true. 
20. F. e. angustifolia. Narrow-leaved European Ash ; Frene a feuilles etroites, 
of the French ; Schmalblattrige Esche, of the Germans. The leaflets of this vari- 
ety are sessile, lanceolate, remotely denticulated, occurring in three or four pairs, 
from an inch and a half to two inches long. The peduncles below the leaves are 
solitary, and about two inches in length. The flowers, which put forth in May 
are naked ; and the samara are entire at the apex, and acute at the base. The 
branchlets are green, dotted with white, and the buds brown. This tree is a 
native of Spain.
