THE NURSERY-LIST 265
Calaciium. A rcwff.
Handled by tu\)crs, ivhich have been kept dry or rested for
some time. The cut surfaces should be well dusted with powdered
charcoal to prevent. deca,y. Place in small pots where the night
temperature is mainta,ined from 60” to 65’. Large tubers, if
sound, may be di\*itlvd and the pieces potted ; some also by
cuttings. New forms raised from seed. See ~rnccoe, page 239. ,
: Calamagrostis. Crra t21 iwa2.
Multiplied by suds sown in autumn or spring.
Calamus. I’d IPI wfw.
1 ncreawd by seeds in heat. See Y&k?, page 371.
Calan&inia, I’t3iiflilfifflWiE.
Propagated mostly by seeds in this country, as they are annuals
or treated as such for flower-garden bloom. C. unabellata, and
orher perennials, may also be grown from cuttings.
Calanthe. Orchidacrw.
Readily handled by separating the pseudobulbs when repotting ;
young bulbs often appe:ir on the top of the old ones ; the old bulbs
wilt &art agaiti the second year.
Calatliaa. AL-mmf~Cff-F.
Tubers may be used for propagation, when produced. A
t:ommon method is to divide the crowns. When secondary growths
or suckers arise, they ma,y be taken ofi below the joints, preferably
in spring before growth starts.
Calceolaaia (Slipperwort). h%rophuZariacelie.
The herbaceous calceolaria.s, treated practically as annuals, are
grown from seed. Sow on finely sifted soil and be very careful
with watering ; it is a gobd pla,n to sink the pan or pot into water
when needed rather than to water on top. Tempera,ture should be
about 60” ; protect from sun. Seeds may be sown from late spring
to early autumn to get plants for the succeeding wint,er and spring.
The shrubby calccolarias may br grown from seeds the same as
the ot.hers, but cuttings may also be employed with good results.
When the plant is trimmed in late summer or early autumn, the
cuttings of firm wood are taken, with two joints. The temperature
of the ho-use should 13 bc about 45” to 50”, and the cut.tings should be
protected from the sun.
