Fungus Creates Zombie Insects On Dogwood, W. John Hayden
Fungus Creates Zombie Insects On Dogwood, W. John Hayden
Biology Faculty Publications
I have something I need to get off my chest. I have an obsession with, of all things, a fungus! And not just any fungus, but a fungus that infects, I am embarrassed to admit, Flowering Dogwood, the VNPS Wildflower of the Year for 2018. Yes, maybe I’ve gone off my rocker. But this fungus is so cool, so devious, so elegantly convoluted and weird—in a creepy sort of way—that I find myself utterly enthralled. Perhaps sharing my obsession with this fungus will prove therapeutic and permit me to return to my more socially respectable obsessive fascination with plants.

In 1753, Swedish botanist Carolus Linnaeus was the first to apply the scientific name Cornus florida to the plant we know as Flowering Dogwood. That simple and straightforward declarative sentence belies the complexity and obscurity of how Linnaeus named this and nearly 6,000 other plants in his seminal work, Species Plantarum. To understand what Linnaeus actually did requires a dive into the arcane world of 18th-century botany. And that is what this article endeavors to accomplish, to explain how Cornus florida, the 2018 VNPS Wildflower of the Year, got its name.

The Flowering Dogwood is a small understory forest tree attaining heights of 5–15 m. Bark of older trees forms a checkered pattern. Twigs are smooth and range from green to purplish-red. Leaves are opposite, mostly ovate to wide-elliptic, and 6–13 cm long; bases may be rounded or tapered, if the latter, often unequally so; apices are acute to acuminate; vein pattern is pinnate with 4–6 secondary veins on each side of the midvein; secondary veins approaching the leaf margin curve toward the apex; upper and lower leaf surfaces range from glabrous to finely pubescent.
