also has the fruit black, as the name implies. I t differs from the
preceding variety chiefly in being of more vigorous growth ; in having
its leaves o f a deep rich green, and in flowering a week later. A
splendid low tree, deserving a place in every collection.

leaves like C. O. obtusàta, and the fruit roundish, and o f a golden

in collections.
Y C. O. 20 aurantiaca Booth is said to have orange-coloured fruit ; but
there are only small plants of it in the London gardens. Mr. Wilson
found, in Ayrshire, a variety with greenish orange fruit. (HooJc.)
¥ C. O. 21 leucocarpa, a variety with white haws, is said to have been
discovered in a hedge near Bampton, in Oxfordshire ; but we have
never seen it.
