Taxonomy
editPyrus ciancioi is morphologically similar to P. communis, P. pyraster, P. spinosa and P. sicanorum in having a frequently persistent calyx, indicating a close evolutionary affinity. It was described by a team of researchers in 2012, and named after the Italian scientist Orazio Ciancio.[3]
Description
editPyrus ciancioi is a spiny tree of more than 5 m (16 ft) height. The leaves are lanceolate and 3.2–6 centimetres (1.3–2.4 in) long, with entire to slightly serrated margins and 1.2–2.5 centimetres (0.47–0.98 in) long petioles. Young leaves are more strongly pubescent on the underside than older leaves. The white flowers appear in corymbs in early April. The fruit is small (2–2.5 centimetres (0.79–0.98 in)) and brownish, and the calyx often persists.[3]
Distribution and ecology
editThe species is known only from the Nebrodi Mountains in northeast Sicily, near the town of Floresta (Province of Messina). It occurs in hedges on quartz-arenite soils.[3]
