Salvia caymanensis (English common name : Cayman Sage = Cayman Sage ) is a species of plant from the genus Sage ( Salvia ). It is endemic to Grand Cayman in the Cayman Islands . This species has been considered extinct since 1967 but was rediscovered in the summer of 2007.

features

Salvia caymanensis is a short-lived, perennial herbaceous plant and reaches a stature height of 50 to 100 cm. The strictly erect stem is covered with fine white hairs at the top and lignified at the bottom. The ovate-lanceolate leaves are between 2.5 and 3 cm long and between 1 and 1.4 cm wide. The light underside of the leaf is covered with fine, white felt hairs, the top, which has a strong aromatic smell, is gray-green. The length of the petioles is a quarter of the length of the leaf blade.

The terminal flower clusters are tight and open. The bracts are pointed lanceolate. The short-stemmed, less than half a centimeter long flowers are whorled . The length of the flower stalks is half the length of the crown . The three-lipped, glandular-haired calyx is blue-green on the top and light green on the underside. The crown is brightly colored sky blue. Their length is twice the length of the cup. The stylus is unevenly two-lipped. The olive-colored Klausen are 1.95 mm long and 0.925 mm wide.

habitat

Salvia caymanensis' habitat includes sandy grasslands, old pastures and clearings. The species often grows in areas that have been destroyed by storms or hurricanes.

Rediscovery

After the devastation caused by Hurricane Ivan in 2004 , conservationists suggested that the conditions for Salvia caymanensis to reappear would be ideal if viable seeds still existed in nature. In May 2007, the Cayman Islands Ministry of the Environment, in collaboration with the Darwin Initiative, placed profiles with a reward of CI $ 1000 for each living specimen of Salvia caymanensis discovered. The wanted poster campaign was scheduled for the species' usual heyday. In July 2007, a resident of Grand Cayman discovered inconspicuous blue flowers while driving the usually busy Queen's Highway, which grew near the roadside and were finally identified as the species Salvia caymanensis , which has disappeared since 1967 . Today 300 individuals are known from two locations. Approximately 18,000 seeds have been collected, 9,000 of which are in the Millennium Seed Bank .
