laxus, and P.
grandiflorus speciosissimus, both distinct and pretty kinds.

P. HIRSUTUS.--North America, 1820. Another handsome, small-flowered
species, of dwarf growth, and having hairy leaves.

P. INODOROUS, also from North America (1738), differs little in size
and shape of flowers from P. grandiflorus, but the flowers are without
scent. The leaves, too, are quite glabrous and obscurely toothed.

P. LEMOINEI BOULE D'ARGENT is a cross, raised in 1888, from P. Lemoinei
and the double-flowered form of P. coronarius. The flowers are double
white and with the pleasant, but not heavy, scent of P. microphyllus. P.
Lemoinei Gerbe de Neige bears pleasantly-scented flowers that are as
large as those of the well-known P. speciosissimus. There is an erect
form of P. Lemoinei named erectus that is also worthy of note.

P. LEWISI, from North America, is hardly sufficiently distinct from some
of the others to warrant special notice.

P. MICROPHYLLUS, from New Mexico (1883), is of low growth, and
remarkable for its slender branches, small, Myrtle-like leaves, and
abundance of small, white flowers. It is a decidedly pretty shrub, but
is not so hardy as the others.

P. SATZUMI (_syn P. chinensis_).--Japan, 1851. A slender-growing
species, with long and narrow leaves, and large, white flowers.

P. TRIFLORUS and P. MEXICANUS are other species that might be worthy of
including in a representative collection of these plants.

This is a valuable genus of shrubs, all being remarkable for the
abundance of white, and usually sweet-scented, flowers which they
produce. They require no special treatment, few soils, if at all free
and rich, coming amiss to them; while even as shrubs for shady
situations they are not to be despised. Propagation is effected by means
of cuttings, which root freely if placed in sandy soil.

PHILLYREA.

P. ANGUSTIFOLIA (narrow-leaved Phillyrea), P. ilicifolia (Holly-leaved
Phillyrea), P. salicifolia (Willow-leaved Phillyrea), P. buxifolia
(Box-leaved Phillyrea), and P. ligustrifolia (Privet-leaved Phillyrea),
are all more or less valuable species, and their names indicate their
peculiarities of leafage. P. angustifolia rosmarinifolia (_syn P.
neapolitana_) is a somewhat rare shrub, but one that is well worthy of
culture, if only for its neat habit and tiny little Rosemary-like
leaves. It is from Italy, and known under the synonym of _P.
rosmarinifolia_.

P. LATIFOLIA (_syn P. obliqua_).--Broad-leaved P
