Description
Daphne gnidium is a shrub with upright branches that grow to 1.5 to 2 m (4 ft 11 in to 6 ft 7 in) tall. The dense lanceolate leaves are dark green with sticky undersides. It bears fragrant white flowers in late spring or early summer. The fruit is a drupe, and is round and red, about 8 mm (0.31 in) diameter. They are produced during autumn.[2][3]
Taxonomy
Three subspecies are currently accepted by the Plants of the World Online database:[1]
- Daphne gnidium subsp. gnidium — Europe, coastal northwest Africa, Canary Islands[4]
- Daphne gnidium subsp. maritima (Rozeira) Capelo, J.C.Costa, Esp.Santo & Lousã — western Portugal[4]
- Daphne gnidium subsp. mauritanica (Nieto Fel.) Halda — northwest Africa in the Atlas Mountains[4]
Recent genetic analysis however suggests that the Atlas Mountains populations are strongly distinct, and would be better treated as a separate species Daphne mauritanica Nieto Fel., but conversely, that the western Portuguese population is not distinct from the rest of the European populations, so subsp. maritima should be regarded as a synonym of subsp. gnidium.[4]
Habitat
Toxicity
Daphne gnidium contains the toxins mezerein and daphnetoxin. All parts of the plant are considered highly poisonous. Skin contact with the sap can cause dermatitis[5] The chance of death is small yet possible within 6 hours after direct consumption. At least severe anabolic and indigestive reactions are expected, which may also trigger lethal allergic reactions.[citation needed]
