Habitat and Ecology
This species was first described in 1983. It grows in the same community with other Sardinian endemics such as Arum pictum, Genista corsica, Ornithogalum biflorum, Bellium bellidioides and Romulea requienii. It is found with species of great phytogeographic interest which are also very rare throughout Italy, such as Helianthemum caput-felis, Viola arborescens, and Coris monspeliensis.

Legally: Currently there is no legal protection for this species, despite the fact that the regional council of Sardinia proposed a draft law in 2001 concerning protection of plant species on the island, and P. sinisica is listed in the Annex as an endemic species. However this law is controversial as it may increase collecting interest in the species.
In situ: Although the Italian Red List of 1992 proposed to set up a nature reserve at Capo Mannu and along the coast of the Sinis peninsula, the site is still threatened by deforestation and receives no legal protection.
Ex situ: No measures taken.
The conservation measures suggested in the Italian Red List of 1992 need to be implemented. Full habitat protection, ex situ cultivation, and fieldwork to determine the exact size of the population are needed.
