A deep acquaintance with Halibut Point of course requires,
or should I say invites knowledge of its plant life. The endeavor touches my
collector's pleasure in discovering and recording as complete a list as
possible. I'm led into fields of botany, ecology, aesthetics, and agriculture that
underpin a full appreciation of Halibut Point's plants. But my fundamental adventure
in this microcosm of the world still revolves around adding new acquaintances.
Carl Linnaeus ushered in the modern era of organized inquiry
by developing a universal system of classification to make possible precise communication
about things encountered. Linnaeus had tramped through Lapland and the Swedish boreal
forests.
Good
God. When I consider the melancholy fate of so many of botany's votaries, I am
tempted to ask whether men are in their right mind who so desperately risk life
and everything else through the love of collecting' plants.'
My explorations at Halibut Point these days don't risk much
more than entrapment by cat brier. But I savor forebears such as Frank
Kingdon-Ward whose expeditions to the Himalayas resulted in titles like Land of the Blue Poppy (1913) and Plant
Hunting on the Edge of the World (1930).
This year I recorded three species new to me on Halibut
Point. Each occurred in a quite different habitat.
|
Polygala polygama (Racemed milkwort) |
It's likely that I have walked right past Racemed milkwort
in previous years. It's nestled into the meadow and blooms only a short period
in late June when more conspicuous features abound in the landscape.

Polygala polygama alongside Houstonia caerulea (Azure bluet) |
Making matters less evident, the color purple recedes against
brown soil. If it hadn't been for the adjacent Azure bluets I might not have
seen them at all. The milkwort's grass-like foliage blends into the turf where
the flowers drew me to a Lilliputian world.

Utricularia vulgaris (Greater bladderwort)

One September day an incongruous
spark of yellow appeared above the surface of a pond that I visit frequently.
It rose above lily pads with no accountable plant in sight.

The flower had risen from a weedy mass named for the tiny
air sacs that keep bladderwort afloat in the growing season, then deflate to
settle the plant to winter dormancy at the bottom of the pond.
The bladders serve nutritional functions for this rootless
species. They ensnare and digest tiny aquatic organisms with a trap door that
ranks among the fastest plant movements known. Triggered
by protruding hairs on the door, they open in about 0.5 milliseconds, sucking
the animal in, and close in about 2.5 milliseconds. This comes to about three
thousand feet per second, almost three times the speed of sound. Some of the
microorganisms are retained to live within the bladder as a mutually beneficial
community of bacteria, algae, and diatoms. [from Wikipedia]

Benthamidia (Cornus) florida (Flowering dogwood) |
On a rainy spring day, walking absent-mindedly through a carpet
of white tissue on the path, I became aware of another novelty in the Park. I
stopped beneath a sapling that otherwise blended into the woodland. It turns
out that the tree we have adopted for splendid lawn specimens is a native plant
in Massachusetts. Its flowers are produced in a small green cluster surrounded
by four showy white bracts, the tissue then on the ground around me.

Looking up the dogwood on the New England Wild Flower
Society's Go Botany website
brought me uncomfortably into the ongoing effort (battleground) of science to
understand all things. The dogwood genus long familiar to me as Cornus (including trees, shrubs, and
bunchberry) now consists of four sub-genera within the family of cornelians. My
Halibut Point log now has to have a place for Benthamidia florida, the natural beauty arcanely named for a Mr.
Bentham about two hundred years ago. Apparently recent genetic analysis has
swung in behind the challengers. Today's gardeners, however, are unlikely to
concede a favorite name for a strange one. Plant exploring should not require
such hazards.
