Daucus edulis (Portuguese: Cenoura-da-rocha) is a critically endangered species of flowering plant in the celery family Apiaceae. It is endemic to Madeira.[2]

Description

Daucus edulis is a long-lived perennial plant, up to 1 metre (3.3 ft) in height. It has a hard woody unbranched stem with annual flowers and light yellowish-green, markedly shiny radial leaves, broadly triangular at the edges with pubescent petioles. It has scattered, paniculate inflorescences. Its fruits are 10–14 by 5–7 millimetres (0.39 in–0.55 in × 0.20 in–0.28 in), oblong to ellipsoid, pubescent and pale when ripe.[3]

The species was previously known as Monizia edulis.[2]

Distribution and habitat

The species is endemic to Madeira Island and Deserta Grande Island and was once native to the Savage Islands.[2] In 2008 its population was estimated to be around 50 individuals in a 226 square kilometres (87 sq mi) area.[4] It extends from the Central Mountain Massif of Madeira and occupies rocky cliffs and terraces with soil accumulations up to 300 metres (980 ft) a.s.l. in Deserta Grande[5] and up to 1,500 metres (4,900 ft) in Madeira.[1][3]

It is mainly threatened by the introduction of exotic species, human collection, fires, droughts, storms, and landslides.[6][1]
