OF HORTICULTURE. 459 
NTCTAdTINEA. An order of herbs, rarely shrubs 
or trees, inhabiting tropical and warm regions, mostly 
America, rarely found in Australia, very rare in Africa. 
Flowers hermaphrodite, rarely unisexual, regular, 
frequently disposed in paniculate or corymbose ter- 
minal and axillary cymes, very rarely solitary or race- 
mose, sometimes umbellulate or capitate, offen with a 
calyciform involuere; perianth small or minute, or rarely 
rather large, obscure or coloured; stamens one to many, 
hypogynous. Fruit various. Leaves opposite and alter- 
nate, sessile or stalked, simple, entire, penniveined, 
The roots of this order are endowed with purgative or 
emetic qualities; that of Mirabilis Jalapa (false Jalap) 
has the nauseous smell of the true Jalap, with which 
confounded. The order comprises twenty- 
three genera and about 215 species.

NYCTANTHES (from nu, nyctos, night, and anthos, 
a flower; in allusion to the flowers opening at the ap- 
proach of night, and falling off at the break of day), 
ORD. Oleacee. A monotypic genus. ‘The species is an 
erect, spreading, stove shrub, or small tree, thriving in 
a compost of sandy loam and fibry peat, to which may 
be added a small quantity of sand and charcoal. 
Propagated, in May, by cuttings of half. ripened 
shoots, inserted im sand, under a bell glass, in bottom 
heat.

“shrubs, of which but one species is as yet introduced. 
The other two are natives of the Malayan Archipelago. 
Flowers few, on long peduncles; corolla tube very long, 
lindrical ; limb spreading, or two-lipped; lobes five, or-

planted out in well-drained turfy loam and sand in the 
stove, and its long shoots trained near the glass in full

water. Where it is impracticable to make a hillock, 
place the tubers in baskets of rich soil, and submerge 
these in the places where the plants are intended to 
grow. The stove species thrive in large pots, wherein 
a similar mixture of soil to the above should be used, 
but they require a house temperature of from 65deg. to 
75deg., and the water heated to abont the last-named 
figure ; though several will succeed if kept much cooler. 
A full exposure to all the sun and light possible is re- 
commended, supposing other plants grown in the house 
will bear it as well as the Nymphæas. As the leaves 
ripen, gradually lower the temperature of the water 
and the house, and allow the tubers to remain in the 
water until the time for repotting comes round—the 
following March. Some growers even dry off the roots, 
by gradually withdrawing all the water, and just keep- 
ing the soil moistened now and then, to prevent dry- 
rot, Ke. Probably the first-named plan is the best. 
Propagated by seeds, which, in most cases, ripen freely. 
They should be sown in small pots of soil, and submerged 
in a shallow warm-water tank, in spring. The seedlings 
will grow away freely, if properly treated, and will flower 
well the same season.
