Botanists Owe Great Thanks to Work of Linnaeus

Twinflowers
The small fragrant twinflowers stand as a symbol to the great Swedish botanist, Carl Linnaeus.

Imagine a very short, creeping, broadleaf, shrublet having such highly perfumed flowers that, with the wind in one’s favor, can be detected and enjoyed from 25 feet away. This was the marvelous sensation that overwhelmed me in the boreal forest to photograph the twinflowers a few days ago.

Just as expected, I found them in full bloom on primarily moss-covered ground along with a few species of clubmosses, Canada Mayflowers and Canada dogwood. These roughly three-inch-tall evergreen plants, growing up from trailing woody stems, have slender flowering stalks each supporting two pink nodding bell-shaped flowers having an exquisite fragrant perfume.

Years ago it was often called deer vine due to its habit of trailing along the ground. The petite blossoms have been described as dangling like little lanterns on Y-shaped lamp posts. What makes this greatly admired wildflower so special is that it is worldwide in its distribution, found in the northern boreal forests of Russia, Finland and Scandinavia as well as the extreme northern reaches of the Midwest and into Canada.

Nodding flowers protect the precious contents from rain, and the fine hairs inside each bell-shaped blossom exclude tiny pilferers. Small bees that will pollinate the plants are attracted by the fragrance and color, and are guided to the nectaries by fine dark lines and a patch of orange color near it. It wasn’t until I took some extreme close-up pictures of a plant that I became aware that the thin stalk contains extremely fine hairs that are tipped with a sticky glob of glue-like material. These probably also deter other unwelcome pilfering insects from overextending their "invitation" to indulge in the nectar of the sweet-smelling flowers.

Carl von Linne was born in Sweden in 1707 just when spring was at its loveliest and the cuckoo was proclaiming the vernal season. He eventually came to be hailed as the father of taxonomy, the prince of botanists, and the Pliny of the North. The system of naming, ranking and classifying organisms, or systematic biological classification, that he devised is still in use today, obviously with plenty of changes. What’s so great about this scientific practice is that scientists worldwide, regardless of their language, can communicate accurately about specific species simply by using their universal Latin name.

Each wildflower, tree, bird, fish, etc. is given a genus-species name that doesn’t change from country to country. A number of years ago when I took a group of Russian botanists through the Ridges Sanctuary we communicated quite well, even though they could speak very little English and I could speak no Russian. I was pleasantly surprised over how many of our northern plants they too had growing at home, and both the Russians and I knew their scientific names.

Carl Linne, being the great teacher he was and so deeply into Latin naming, invented the name Linnaeus (pronounced lin-NEE-us) in allusion to a large and ancient tree of the small-leaved linden. To the people in the Swedish province of Smaland, his home, this tree was known as the "linn." These trees also grew on the Linne property known in the 17th century as Linnegard.

It was one of his mentors from Netherlands, Dr. Jan Frederik Gronovius who, very likely with subtle but strong suggestions from Linnaeus, selected this typical woodland blossom to transmit the great master’s name to posterity. To Linnaeus the twinflower possessed some of his own qualities, "lowly, insignificant, flowering for a brief space." This precious fragrant little wildflower would serve as the monument of the man of flowers. It also was a family favorite, was used on their China and as a part of their family crest.

One of Linnaeus’s most important contributions to the science of botany was the recognition that plants reproduce sexually. It’s easy to imagine that this notion was very unpopular when he first introduced it. One of his former teachers and fellow botanists, Johann Siegesbeck, snorted in disgust, upon hearing of Linnaeus’s new system, "Who would have thought that bluebells, lilies and onions could be up to such immorality?"

Linnaeus was not one to casually brush aside such a caustic remark. He retaliated by naming a very common ugly little weed, "Siegesbeckia orientalis." To present-day botanists who largely concern themselves with matters of taxonomy, the great Linnaeus is just plain "L.", the letter in scientific manuals that immediately follows the scientific species name and indicates the naming of an outstandingly large number of important organisms.

Tour Sweden and you will find that Linnaeus is greatly honored to this day. His picture appears on the 100 kronor bill, a large statue of him occupies an important place in a Stockholm park, and a chiseled silhouette of him at his graveside is labeled in Latin, Princeps botanicorum, "The Prince of Botanists."

Every time I kneel down to admire the delicate twinflower and inhale its refreshing perfume I think of that giant of a man, Linnaeus, who contributed so much to science.
