C. OXYACANTHA PUNICEA flore-pleno (Paul's double-scarlet Thorn), is one
of, if not the handsomest variety, with large double flowers that are
of the richest crimson. Other good flowering kinds include C.
Oxyacantha praecox (Glastonbury Thorn); C. Oxyacantha Oliveriana; C.
Oxyacantha punicea, with deep scarlet flowers; C. Oxyacantha rosea,
rose-coloured and abundantly-produced flowers; C. Oxyacantha foliis
aureis, with yellow fruit; C. Oxyacantha laciniata, cut leaves; C.
Oxyacantha multiplex, double-white flowers; C. Oxyacantha foliis
argenteis, having silvery-variegated leaves: C. Oxyacantha pendula, of
semi-weeping habit; C. Oxyacantha stricta, with an upright and stiff
habit of growth; C. Oxyacantha Leeana, a good form; and C. Oxyacantha
leucocarpa.

C. PARVIFOLIA.--North America, 1704. This is a miniature Thorn, of slow
growth, with leaves about an inch long, and solitary pure-white flowers
of large size. The flowers open late in the season, and are succeeded
by yellowish-green fruit.

C. PYRACANTHA.--Fiery Thorn. South Europe, 1629. This is a very
distinct species, with lanceolate serrated leaves, and pinkish or
nearly white flowers. The berries of this species are, however, the
principal attraction, being orange-scarlet, and produced in dense
clusters. C. Pyracantha crenulata and C. Pyracantha Lelandi are worthy
varieties of the above, the latter especially being one of the most
ornamental-berried shrubs in cultivation.

C. TANACETIFOLIA.--Tansy-leaved Thorn. Greece, 1789. This is a very
late-flowering species, and remarkable for its Tansy-like foliage. It
is of unusually free growth, and in almost any class of soil, and is
undoubtedly, in so far at least as neatly divided leaves and wealth of
