366 THE GREEN-HOUSE. [chap. xi. 
without injuring the part of the petiole which 
was attached to the stem* has been known to 
grow and form a plant. Several handsome 
hybrids have been produced, by applying the 
pollen of F. fulgens to the stigma of F. glo- 
bosa, F. conica, and F. gracilis. It may here 
be mentioned, that whenever hybrids are to 
be raised, by fertilizing one plant with the 
pollen of another, the anthers of the flower 
that is to produce the seed, should be re¬ 
moved with a pair of scissors, before they 
burst. The pollen from the other flower 
which is to form the hybrid, should be after¬ 
wards applied with a camel-hair pencil to 
the stigma of the flower, which is to produce 
the seed; and a bit of thread should be tied 
round the flower-stalk, in order that the 
seed-pod may be saved, and set apart. All 
hybrids may be made in the same manner; 
but it must always be remembered that 
flowers will not hybridize properly, unless 
they are naturally nearly allied. 
Calceolarias .—Perhaps no plants have ever 
been hybridized more extensively than these.

splendid plants that we are continually seeing
