TRICHOMANES. 
greenhouse temperature, and will receive a 
little shade from the sun, which will pro- 
long their flowering. Afterwards, if they 
are not required to be grown on larger 
without delay, they may be treated through 
the summer like the rest of the greenhouse 
hardwooded stock ; if, on the other hand, 
it is deemed desirable to grow them on to 
a larger size without loss of time they 
should be submitted to a temperature such 
as hitherto used during the growing season. 
Be careful that the shoots as they extend 
do not get entwined round the wires of the 
trellis, or there will be some difficulty ex- 
perienced in getting them loose to place 
upon a larger one, which they will require 
in the course of another year or two, when 
more root-room will be needed ; thus 
treated the plants will last for many years. 
When required for training up a pillar 
or rafter, it is well to grow them for a 
season or two in pots so that they may get 
strong before the roots are turned out in a 
border ; this should be well drained and 
consist of good fibrous soil with enough 
sand and crocks, or charcoal, to keep it 
sweet and porous. Have the shoots from 
the first regularly trained, not allowing 
them to become entangled, and as the 
space they are to fill gets covered the 
superfluous growth may be shortened back 
immediately they have done flowering each 
season. When the soil gets exhausted 
some of the surface may be removed every 
spring and replaced by new, and when 
grown in this way, or in pots, manure- 
water will be a great assistance when the 
soil becomes filled with roots. 
There is a variegated form of this plant 
that will succeed by being treated in the 
above manner. It is scarcely so desirable 
a variety as the green-leaved sort. 
Insrects.—The leaves, from their stout 
nature, do not suit the tastes of red spider 
or aphides ; these insects, however, will 
live upon the plant, but can be easily kept 
down by syringing. For thrips, which 
are sometimes troublesome, fumigate, or 
syringe with tobacco-water. If scale makes 
its appearance it must be carefully removed 
by the use of sponge and brush. For 
mealy bug, syringe and dip with a strong 
solution of insecticide in the winter when 
at rest. 
TRADESCANTIA. 
The creeping species of Tradescantia are 
very useful for draping hanging baskets 
containing other plants, as, if required, 
their pendent shoots can be made to cover 
the whole outside of the baskets. They 
are also particularly adapted for growing

as an edging to plant stages, or trailing 
over rock-work in the stove. 
Their cultivation is as easy as possible, 
as the shoots root like weeds at any time 
of the year in a moderate heat, kepta little 
but not too close, with shade from the sun. 
When rooted they may be put singly in 
small pots, and as soon as fairly established 
planted where they are to remain. 
The following are adapted for growing 
in the way described :— 
T. discolor. 
America. 
T. discolor varregata. Has neat varie- 
gated foliage. A native of Mexico. 
InsEcts.—Few insects molest Trades- 
A pretty kind, from South 
cantias if the precaution is taken to use 
the syringe daily in the growing season. 
Should aphides affect the points of the 
young shoots, fumigate. 
TRICHINIUM. 
Low-growing annuals with somewhat 
singular flowers, but not possessing very 
much merit. 
They can be raised from seeds sown in 
spring in a pit or greenhouse in the usual 
way, with additional pot-room as required. 
The best are :— 
T. alopecuroideum. Flowers red and 
yellow, produced in summer. A native of 
Australia. 
T. Manglesti. Flowers white and pink, 
forthcoming in summer. From Australia. 
TRICHOMANES. 
A genus of beautiful little filmy Ferns, 
many of them requiring similar treatment 
to the Hymenophyllums and Todeas, others 
doing better with a little more warmth.
