Triantha Occidentalas: Flowering Plant Eats Insects Walking up Its Sticky Stalk

Triantha occidentalas won't bite. Although botanists say, if a tiny insect such as gnat or midge walks up to its sticky stalk, this flowering wetland plant that typically exists on Vancouver Island and along the Pacific coast will literally suck the life out of it.

A Times Colonist report said this plant is not a new species that botanists have known of its presence for roughly 150 years.

However, researchers at the University of British Columbia have found that the Triantha occidentalas has evolved into a new line of carnivorous plant, with the ability to ingest a captured prey's nitrogen and phosphorus to survive in and endure a habit that's otherwise poor in nutrients.

This discovery is substantial since, since the time of Charles Darwin, it is only the 12th identified carnivory evolution in the world of plants, and the first time such a trait has been detected in the Alismatales order, which has approximately 4,500 species of aquatic flowering or tropical plants. This was the first new carnivorous plant scientists discovered in two decades.

Findings of the study by Quianshi Lin, a UBC botany doctoral student, and Prof. Sean Graham, together with the University of Wisconsin, Madison's Tom Givnish, were published in the National Academy of Sciences.

Carnivorous Plants

According to Graham, carnivorous plants have captivated people since the Victorian period as they turn the usual order of things on their heads; this is a plant that teats animals.

He added, even though the study site was on the Cypress Mountain of North Vancouver, one can drive one hour out of Nanaimo or Victoria and find the plants. Specifically, it lives in wetlands in open areas to the alpine from sea level.

A similar Vancouver Reports said that what sets the Triathna occidentalas apart from the rest of carnivorous plants is that its capture site is not in the flower, although along the stem, where a series of small sticky hairs are strapping small insects.

Lin explained that this appears like a conflict between carnivory and pollination since "you don't want to kill" the insects that help in reproduction.

The study authors discovered that the plant could balance its taste for bugs that have pollination since the tiny trapping hairs on its stem are not strong enough to hold major pollinators like butterflies and bees.

Graham explained the tiniest insects such as midges, small flies, and tiny beetles are held, although the researchers never found any butterfly or bee. Describing the study found, he said it is a case where this particular plant can have its cake and consume it.

Significant Uptake of Nitrogen Found

In their study, Lin attached fruit flies and had their flowering stem labeled with nitrogen isotopes. This offered a tracking system for the tracing by the plant of nitrogen uptake.

UPI reported that other neighboring plants like the carnivorous sundew and non-carnivorous species were used in this research. Analysis showed a substantial uptake of nitrogen by Triantha occidentalas, showing it received more than half of its nitrogen from the prey.

The research also showed the sticky hairs on the stuck generated by a digestive enzyme numerous carnivorous plants use so they can absorb phosphates from prey.

In science, Graham explained, there are always speculations and new hypotheses. A lot are tested, although many of them turn out to be untrue, he added. It is unusual; therefore, it's the reason it is an extremely substantial find.
