The Project Grows! Where are we seeing these species?

Thank you for your work, searching in your nearby natural areas for Marsh Marigold (Calthus palustris) and Lesser Celandine (Ranunculus ficaria). The observations of each species have more than doubled on iNaturalist since the beginning of this project! Truly a group effort here, it is great to see. How do the new observations break down? There are a total of 94 observations detailing unique locations.

There were many from North America. New observations of Marsh Marigold are numerous in Vermont, with others coming in from IL, MI, OH, Ontario, and PA. Lesser Celandine, invasive in N. America, has been observed recently in Washington DC, as well as IL, NC, NJ, NY, OH, PA, and VA.

In Europe, observations of both species have been made in Belgium, Denmark, England, France, Italy, Netherlands, Portugal, Spain, Wales, and even the Faroe Islands. Interestingly, Lesser Celandine is not native on the Faroe Islands.

From the start of the project to now, ...more ↓

Description

Upon further investigation, this appears to be a non-native species. A yellow marsh-marigold of some sort. Any ideas?

The leaves are rounded, unlike western buttercups and the flowers have at least 8 pointy petals, much like the native white marsh-marigolds.
