Which flower appears in Georgia O'Keeffe's 1930 painting Jack-in-the-Pulpit No. IV?

Georgia O'Keeffe's 1930 painting Jack-in-the-Pulpit No. IV depicts a jack-in-the-pulpit flower.

The work belongs to O'Keeffe's celebrated series of paintings based on the jack-in-the-pulpit plant. She enlarged the flower dramatically, presenting its central structures as bold, abstract shapes. The series demonstrates how she used close-up views of natural subjects to make familiar forms appear unfamiliar and monumental.

Jack-in-the-pulpit is a woodland wildflower native to eastern North America. Its name comes from the hooded spathe, which resembles a preacher standing in a pulpit. O'Keeffe painted several works in the series in 1930, so the number in the title matters: Jack-in-the-Pulpit No. IV is one specific painting, not the whole group. The series is also separate from her paintings of jimson weed, black iris, and canna lilies.
