Description

It is a deciduous shrub growing to 2–3 metres (7–10 ft) tall; its natural mature size is unknown, as all existing specimens have been heavily browsed by goats, limiting their growth. The leaves are oval, 10–50 millimetres (0.4–2.0 in) long and 5–35 mm (0.2–1.4 in) wide, with a petiole 1–4 mm (0.04–0.16 in) long; the margins are lobed, with 6–8 lobes on each side.[3][4]

Conservation

The only known population, found in 1991, consists of 200–250 plants growing on the Monti Iblei area, in Buccheri, in southeast Sicily near Syracuse. This population are all thought to derive from possibly just one clone, or at the most only a very few distinct individuals. Its natural habitat is temperate forests and Mediterranean-type shrubby vegetation,. It is threatened by habitat loss. The IUCN list this species as Critically Endangered.[1]

gollark: Firefox is open source, so you can see they're not doing anything massively evil. But they also do rely on Google paying them to make Google the default search engine, which is not ideal.
gollark: It's going to be easier for Google to gather data from you in *their browser* than Firefox.
gollark: Some of it probably does.
gollark: Or claim to only support it but work on Firefox anyway...
gollark: But lots of things only support Chrome, which is very bad for the future of internet standards.
