The modest flower is pollinated by small flies emerging in spring in search of dead animals. Therefore, the flower has the color of decomposing flesh. It opens secretively at ground level, under the litter, or even partially berried in soil. To observe it, one has to dig the plant out from forest litter. The flower is lacking petals; sepals are often damaged by animals and thus may be missing, too (here only one of 3 is intact).
