You Might be a Botanist

You Might be a Botanist
an original poem by Illinois Botanizer
If you take the time to identify lawn and garden weeds before pulling them out…
If you know at least a dozen different terms to describe “hairy”…
If you store a dissecting microscope on your kitchen table…
If you have no problem remembering botanical names, but keep forgetting common names…
If you have botany manuals in your bathroom as reading material…
If you tell your family you spent all week looking at plant specimens in the herbarium, and they give you a funny look…
If you go out looking at plants during your day job, and then go out looking at plants on your day off…
If you wear your loupe out in public… (my wife calls it my nerd necklace)
If there are Desmodium seeds on your bath towels, (and you know what Desmodium seeds look like)...
If you open up random books and plant leaves fall out…
If you are terrible at yard work and only mow your lawn once a month…
If your bookshelf is overflowing with plant field guides…
If you pick seeds off your clothes and identify them before tossing them away…
If the book to the flora of your state is always within arms reach…
If you have bags of plants in the crisper drawer of your refrigerator…
If everyone who hears about your occupation thinks you grow marijuana…
If the phrase “scarious margins on the involucral bracts” makes sense to you (and you know what species I might be referring to!)…
If you are out all day collecting plants, and then come home, shower, eat, and then return to looking at plants…

Hepatica acutiloba

     The Doctrine of Signatures is a rather bizarre concept that was embraced by herbalists of long ago. The idea comes from a couple of religious Europeans who suggested that God marked his creations with a signature that suggests its purpose to mankind.  Plants that resembled body parts were thought to have been created in order to treat ailments of that body part.  In the days before pharmacuticals, plants were heavily collected and used as medicine.  The idea was that since God is responsible for disease, he must also have created a natural cure for the disease.
     Such is the story behind the plant named Liverleaf (Hepatica acutiloba). In fact, even the scientific name of this plant refers to its resemblance to the liver as "Hepatica" comes from the Latin "epatikos" meaning "affecting the liver."  This plant has leaves that are distinctly three-lobed and in the dormant season they turn liver-colored (brown).  The human liver is also three-lobed and brown, therefore it was once thought that this plant could be used to treat liver disease.  However, this species is in the Ranunculaceae (the Buttercup family), which is a family of plants that are largely toxic!

     Liverleaf is generally distributed throughout Illinois, but is restricted to undisturbed woodlands.  It has no petals as the showy portions of the flower are technically sepals. It is one of our earliest spring wildflowers.

Symplocarpus foetidus

     


     
     The earliest spring wildflower to emerge from dormancy is skunk cabbage (Symplocarpus foetidus). In fact, this species flowers so early, it could be considered a winter wildflower! Skunk cabbage flowers have the ability to heat up the surrounding snow, which promotes melting so it can poke its fragrant flowers up through the ground. 
     Skunk cabbage has unusual flowers, like all members of the Arum family (Araceae). They consist of a spathe, an outer sheath which surrounds the inflorescence, and a spadix, a fleshy stem on which tiny flowers are produced.
     

Newly emerging leaves
     Many plants that produce flowers at the surface of the ground are brown in color and stink like decaying organic matter. This is to attract pollinators, typically flies, but this also lures in beetles and ants as well. Pollinators are also attracted to the flowers because of the heat they produce which leads to another interesting evolutionary strategy.
     Why flower so early? On the one hand, there are not many pollinators available in the early spring because it is too cold for them to be active or present. However, the few insects that are active and present are looking for food and warmth. The skunk cabbage receives virtually exclusive attention because it flowers when nothing else is available.
     “Symplocarpus” is Greek for “connected fruits” and “foetidus” translates from Latin to “malodorous” meaning “smelling very unpleasant.” From this, the term “fetid” derives.

     These photos were taken in a forest preserve in Cook County on March 18, 2016.  There is a healthy population at this location.
