are to be found on it about the time when the nightingale is in full song. The 
same property of attracting nightingales is ascribed to the common hawthorn, 
in La Théorie du Jardinage, §c., published in 1709.

Variety. 
¥ C. p. 2 altaica ; C. altaica Led., Lod. Cat. ( fig. 696. in p. 393.) ; has the 
leaves somewhat larger than the species, and they appear a little 
earlier. 
It forms an upright, rigid, rather slow-growing tree, without thorns. It has 
a few small branches, and is not densely clothed with leaves. It has a starved 
and somewhat stunted appearance, and is readily known by the purple colour 
of its young shoots. The bark of the old wood is of a dark purple or brown 
colour, and rough and scaly. The fruit is small, round, and most commonly of 
a dark purple; but it varies to pale yellow, or a milk white, and red, on the 
same plant. It ripens about the end of July, and is very soft and juicy, but 
soon drops off. The tree is interesting from its early flowering, and the dark 
colour of the anthers of its flowers, which contrasts strongly with the white- 
ness of the petals. The leaves are also large, and of a peculiar shape.

Sect. Char. Leaves small, and not lobed as in the preceding section; furnished 
with numerous parallel nerves, somewhat like those of C. punctata. Spines
