Gesneraceew. A genus comprising six species of stove 
herbaceous perennials, with catkin-like scaly stolons, in- 
habitants of Mexico and Central America. Flowers red, 
whitish-yellow, or painted, in terminal, leafless, alternate 
racemes ; corolla tube declinate; throat broadly oblique; 
limb broadly lobed, spreading, rotundate. Leaves opposite, 
soft, often cordate, on long stalks. Nægelias are exceed- 
ingly ornamental plants, both on account of their flori- 
ferous habit, and also because of their beautifully marked 
foliage. This latter should be carefully preserved from 
drip, and the use of dirty water avoided for syringing 
purposes; otherwise, a sediment collects amongst the tiny 
hairs on the surface of the leaves, and renders the whole 
plant unsightly. The stolons or roots, as they are 
generally termed, should be potted up in spring or 
summer, according to the time of year at which the plants 
are required to flower. A light compost of peat, leaf 
soil, and a small quantity of loam, is most suitable; it 
should only be pressed moderately firm in potting. Pots 
5in. to 6in. in diameter, are large enough, about three 
roots being placed in the latter, or only one in the 
former size, covering them with lin. of soil. If potting 
is deferred until after midsummer, the flowering season 
is often prolonged throughout the winter, especially 
with N. cinnabarina, a late-flowering and beautiful 
species. When the foliage dies away, the pots, with 
their contents, should be stored and kept quite dry, 
until the season for starting arrives again. Nzegelias 
are readily propieda by the increase of stolons ; also by 
- cuttings made of the young stems or matured leaves, 
and inserted in a close propagating frame. See also

NAIADACEZ. An order of marine or fresh-water, 
annual or perennial herbs, widely distributed over the 
globe. Flowers hermaphrodite, moneecious or dicecious, 
small, often inconspicuous, spicate, racemose, or disposed 
on pedunculate, terminal, or axillary spadices, bracteate 
or ebracteate. Leaves gubmersed, emerging, or floating, 
in seape-bearing genera radical, linear, or rush-like ; stem 
leaves opposite, alternate, or very rarely ternately whorled, 
essile or petiolate, oblong, linear, or capillary, sheathed 
base. The order comprises sixteen genera, and about 
species. Examples: Aponogeton, Nuias, and Tri- 
NAILS. Nails are required in quantity for training 
fruit-trees and various other plants on garden walls, and 
are made of cast iron specially for the purpose. Any 
of another description would bend rather than enter a 
hard substance, such as that of a brick, while the cast- 
iron ones may invariably be driven in a horizontal 
direction far enough to retain a hold. They are said 
to be much preserved from rust by heating almost to 
redness before using, and throwing them into linseed 
oil. Wall Nails are made in different lengths, and as 
they are usually sold by weight, the smaller sizes 
represent a much greater number in any given weight 
than the larger ones. Nail bags are very handy for 
holding a stock of shreds, &., whilst nailing up trees 
or plants from a ladder. They are best made from 
leather in the shape of an open pocket, and held in 
position by a narrow belt and a shoulder strap. One 
or more upright shea’ or divisions are frequently 
made inside, in which the workman’s knife and hammer 
may be placed when either are not in use. Canvas 
bags answer the purpose equally well when leather ones 
are not procurable. 
NAMA (from nama, a stream of water; alluding 
to the natural place of growth). ORD. Hydrophyllacee. 
A genus comprising fifteen species of low, annual, peren- 
nial, or at length suffruticose, herbs, of which one is a 
native of the Sandwich Isles, and the rest are found in 
North-west America and Mexico, one of them extending 
in South America as far as Brazil. Flowers often blue, 
small or mediocre, solitary in the axils, sessile or shortly 
pedicellate, or irregularly cymose at the apices of the 
branches. Leaves alternate, petiolate, sessile or decur- 
rent, entire. The species are not much grown. They 
thrive in sandy loam or in any ordinary good garden 
soil, and require a sheltered situation in summer, and 
protection throughout the winter. Propagation may be 
effected by divisions, or by cuttings, made in spring, and 
inserted in a close, warm frame or propagating house. 
N. Parryi is the best known member of the genus. 
N. Parryi (Parry’s). fi. lilac-purple, arranged in unilateral, 
dense, scorpioid clusters, on a 3 branched panicle; corolla 
about lin. long. l en repandly-toothed, villous, ‘hirsute.

NANDINA (from Nandin, the vernacular name of the

The species is an erect, half-hardy or greenhouse, ever- 
green shrub, thriving in loam and sandy peat. It may 
be propagated by cuttings of ripened shoots, inserted in 
sand, under a handlight. Probably this plant would 
prove hardy in a sheltered place in the more southern 
counties.

Fasse A monotypic genus, the species being a low, 
gregarious, unarmed, stove palm, with a tufted, creeping 
caudex. It thrives in a compost of sandy loam, to which 
some leaf soil and a little charcoal may be added with 
advantage. Efficient drainage is an important essential. 
Propagated by seeds; also by offsets, when any can be 
_ procured and detached without injury to the parent 
plant.
