But even here there are monstrosities in the true sense. The asparagus
or sweet potato stem occasionally broadens out into a ribbon, and it
passes as an abnormity. The same thing takes place in the flower
cluster of cockscomb (_Celosia cristata_), and if it failed to produce
a strange fan-shaped and highly colored and crested top the owner
would complain that her seed had given her only an inferior pigweed,
and therefore not come true to name. The attractiveness of the
cockscomb resides in the strange habit the plant has of broadening the
upper end of the flower stalk out into a form that is truly monstrous.
And this brings me to speak of a form that attracted my attention
during the present season, samples of which are shown in Fig. 4.
[Illustration: FIG. 4.--MONSTROUS BLOSSOMS OF FOXGLOVE.]
The striking feature of the specimens of foxglove (_Digitalis
purpurea_) under consideration is the production of an enormous
somewhat bell-shaped flower at the extremity of the long racemose
inflorescence, and at a time when only a few of the lowermost blossoms
upon the stem have opened. The normal digitalis flower has a large
pendant purple corolla much spotted upon the middle lobe of the larger
and lower lip. On the other hand, the truly monstrous flowers, two to
three inches across, are borne terminally and are quite uniformly
bell-shaped, with the lobes from twelve to fourteen and spotted evenly
over all the surface. The four stamens of the normal flower have
increased to twelve in three examined and to thirteen in another.
These stamens are normal in size and situated upon the corolla tube,
except that there is no indication of their being in long and short
pairs.
The single pistil is many times enlarged in the monstrous blossom--in
one instance two thirds of an inch in diameter for the ovary. Within
the outer ovarian wall there was a circle of five petaloid pistils,
some showing the placentæ and ovules intermixed with the pink and
purplish petaloid expansions.
Within the circle above mentioned there was a second pistil, tipped
like the original with petal-like lobes instead of a stigma. The
column was found so closely built up that the parts would not
separate, and a cross-section was made through it, which showed that
the pistil had a greenish central stalk around which the ovarian
cavities were scattered quite irregularly, all bearing numerous
ovules. In the flowers with twelve stamens there were four tips to the
stigma, and the eight cavities were to be distinguished in the ovary,
although they were not arranged in any regular order and not uniform
in size. In short, the transections of these resembled the seed
cavities seen in a slice of a large tomato of the "trophy" or
"ponderosa" type.
