Schiedea adamantis

Schiedea adamantis, commonly known as Diamond Head schiedea, is a species of flowering plant in the family Caryophyllaceae, that is endemic to the island of Oahu in Hawaii. It inhabits low shrublands on steep slopes along the northwest rim of Diamond Head Crater. Associated plants include nehe (Lipochaeta lobata var. lobata), kāwelu (Eragrostis variabilis), akoko (Euphorbia degeneri), and ilima (Sida fallax). There are only about 30 individuals remaining, and they are threatened by habitat loss.

Schiedea adamantis is a rare Hawaiian plant that is endangered due to climate change and habitat loss. It's also known as the flower of love because it's said to bring good luck in love affairs.

This plant has deep green leaves that are covered with silvery scales, and bright pink flowers that bloom in the spring. It can be found growing on the slopes of Haleakala National Park on Maui, and is a favorite of horticulturalists and gardeners worldwide. This exquisite plant is at risk of becoming extinct due to the changing climate and loss of habitat.

Gynodioecy
Gynodioecy is a rare breeding system that occurs in certain species of flowering plants in which female and hermaphroditic individual plants coexist within a population. Inbreeding depression was found to be an important factor in the maintenance of gynodioecy in S. adamantis. Inbreeding depression, due to selfing in the hermaphrodite plants, is likely caused by the presence of many mutations of small effect.
