NEGUNDO, Box-Elder (Mceuch.) 
Nat. Order, Aceracece. Of the single 
species known in this country ( fraxini - 
folium) there are two varieties, which, 
with their parent, are closely allied to the 
maple, hut distinguished by their pinnate 
leaves. They are handsome trees, of 
medium size, deciduous, and suitable or¬ 
naments of large shrubberies, or for filling 
the fronts of detached groups. They 
succeed best in light soil, and are easily 
increased by cuttings or seed. Syn. 
Acer nequndo , Nequndium americanum. 
NEMOPANTHES (Baeinesqtje.) 
Nat. Ord. Aquifoliaceae. N. canadensis , 
the only species, is an ornamental de¬ 
ciduous shrub, formerly included in the 
genus Ilex. It is a native of North 
America, and requires to be grown in 
peat. Increased by seed or layers. 
NITPvAPIA (Schreber.) Nat. Ord. 
Nitraceee. Curious little thorny shrubs. 
The original species, N. Schoberi, is a 
native of the salt plains of Siberia, it has 
purplish-blue flowers; the variety caspica 
from the Caspian desert, and has white 
blossoms; both these require a liberal 
mixture of salt with the earth they are 
grown in, or they do not flower well. 
N. tridentata, from Barbary, succeeds 
without this addition. They are all more 
curious than beautiful, and may be in¬ 
crease!! by cuttings or layers. 
NYSSA, Tupelo (Linn.) Nat. Ord. 
Santalacere. North American, dwarf, de¬ 
ciduous trees, with spreading heads, va¬ 
rying in height from ten to twenty feet. 
In its native country. Ah denticulata rises 
to the height of eighty or a hundred feet, 
and is described as of great singularity 
and beauty. It produces a fruit which 
resembles small olives, and they are pre¬ 
served and eaten by the Mississipians in 
the same manner. With us, the whole 
of the genus are shrubbery plants, thriving 
best in damp situations, and are propa¬ 
gated chiefly by layers. 
OLE A, Olive (Linn.) Nat. Order, 
Oleacece. The European olive, 0 . saliva, 
is an important plant, on account of its 
fruit, and the oil extracted from it. The 
original species may be grown in the 
southern parts of the kingdom, by sta¬ 
tioning it in a sheltered place, or trained 
against a wall; it is, however, only to be 
regarded as an ornamental object, for it 
is seldom the fruit attains any degree of 
perfection in the open air; the fragrance 
of the flowers is another inducement to 
its culture, and in favorable seasons 
these are abundantly produced. The 
olive delights in light rich earth, such as 
a mixture of peat, loam, and manure, and 
cuttings may be struck early in autumn, 
under a hand-glass upon a warm border, 
or it may be grafted upon the common 
privet. 
ONONIS, Rest Harrow (Linn.) Nat. 
Ord. Leguminosee. Two species of rest 
harrow may be included in our list of 
hardy shrubs. They are rotundifolia , 
rising about a foot high, and fruticosa , 
attaining nearly double the stature; both 
are deciduous, and have pleasing pink 
flowers. They are rigid-growing plants, 
armed with spines, and succeed best in 
peat soil. They are appropriate occupants 
of rockwork, and sloping banks in a sunny 
position. Propagation is effected by layers 
or seeds. There are a few other species, 
which are hardy and of suffruticose habit, 
but devoid of interest sufficient to repay 
their culture. 
PALIUPlU S, Christ s-thorn (Gartner.) 
Nat. Order, Rhamnaceee. P. australis is 
a native of the south of Europe. It is a 
handsome free-flowering shrub, with 
purplish-green blossoms, flexible stem, 
and very prickly; the fruit is very singu¬ 
lar, being roundish, and buckler-shaped, 
having a projecting border, which gives 
it the appearance of a head with a broad- 
brimmed hat on. It is by some supposed, 
and they are borne out by the testimony 
of many credible travellers, that the 
crown of thorns put upon the head of 
Christ was formed of this plant; it is 
one of the commonest plants of Judea, 
and the ease with which it may be bent 
lends great probability to the supposition. 
With us it grows freely in common soil, 
and may be increased by layers or seed. 
PAYIA (Boerelaave.) Nat. Order, 
AEsculaceee. The greater part of this 
genus is a separation from that of AEscu- 
his. The species are handsome free-
