While visiting Ballston Creek Preserve and continuing my wildflower inventory at this preserve, I spied this cluster of blooming plants –
Nightcaps (Anemone nemorosa var. quinquefolia)
The Swedish botanist, C. A. M. Lindman, illustrated it in his book entitled “Bilder ur Nordens Flora” –
Compare the above photo with that painting. They appear essentially identical to me.
Now, contrast each of those with this photo of Wood Anemone (Anemone quinquefolia).
Note the differences in the appearance of the leaves as well as the number of petals on the flowers.
This is only the second site where I have found this particular species. I initially discovered Nightcaps while conducting a wildflower inventory at Ann Lee Pond Nature & Historic Preserve in the Town of Colonie.
