TOUCH-ME-NOT FAMILY (Balsaminaceae)
Jewel-weed; Spotted Touch-me-not; Silver Cap; Wild Balsam; Lady's
Eardrops; Snap Weed; Wild Lady's Slipper
Impatiens biflora (I. fulva)
Flowers--Orange yellow, spotted with reddish brown, irregular, 1
in. long or less, horizontal, 2 to 4 pendent by slender footstalks on a long
peduncle from leaf axils. Sepals, 3, colored; 1 large, sac-shaped,
contracted into a slender incurved spur and 2-toothed at apex; 2 other
sepals small. Petals, 3; 2 of them 2-cleft into dissimilar lobes; 5 short
stamens, 1 pistil. Stem: 2 to 5 ft. high, smooth, branched, colored,
succulent. Leaves: Alternate, thin, pale beneath, ovate coarsely
toothed, petioled. Fruit: An oblong capsule, its 5 valves opening
elastically to expel the seeds.
Preferred Habitat--Beside streams, ponds, ditches; moist ground.
Flowering Season--July-October.
Distribution--Nova Scotia to Oregon, south to Missouri and
Florida.
These exquisite, bright flowers, hanging at a horizontal, like jewels
from a lady's ear, may be responsible for the plant's folk-name; but whoever
is abroad early on a dewy morning, or after a shower, and finds notched
edges of the drooping leaves hung with scintillating gems, dancing,
sparkling in the sunshine, sees still another reason for naming this the
Jewel-weed. In a brook, pond, spring, or wayside trough, which can never be
far from its haunts, dip a spray of the plant to transform the leaves into
glistening silver. They shed water much as the nasturtiums do.
When the tiny ruby-throated humming bird flashes northward out of the
tropics to spend the summer, where can he hope to find nectar so deeply
secreted that not even the long-tongued bumblebee may rob him of it all?
Beyond the bird's bill his tongue can be run out and around curves no other
creature can reach. Now the early-blooming columbine, its slender
cornucopias brimming with sweets, welcomes the messenger whose needle-like
bill will carry pollen from flower to flower; presently the coral
honeysuckle and the scarlet painted-cup attract him by wearing his favorite
color; next the jewel-weed hangs horns of plenty to lure his eye; and the
trumpet vine and cardinal flower continue to feed him successively in
Nature's garden; albeit cannas, nasturtiums, salvia, gladioli, and such
deep, irregular showy flowers in men's flower beds sometimes lure him away.
Familiar as we may be with the nervous little seed-pods of the
touch-me-not, which children ever love to pop and see the seeds fly, as they
do from balsam pods in grandmother's garden, they still startle with the
suddenness of their volley. Touch the delicate hair-trigger at the end of a
capsule, and the lightning response of the flying seeds makes one jump. They
sometimes land four feet away. At this rate of progress a year, and with the
other odds against which all plants have to contend, how many generations
must it take to fringe even one mill pond with jewel-weed; yet this is rapid
transit indeed compared with many of Nature's processes. The plant is a
conspicuous sufferer from the dodder.
The Pale Touch-me-not (I. aurea)--I. pallida of Gray--most
abundant northward, a larger, stouter species found in similar situations,
but with paler yellow flowers only sparingly dotted if at all, has its
broader sac-shaped sepal abruptly contracted into a short, notched, but not
incurved spur. It shares its sister's popular names.
