WIKIPEDIA - Liliaceae.

Individual species and genera may have more or less derived formulas. The family evolved approximately 68 million years ago during the Late Cretaceous to Early Paleogene eras. Liliaceae are widely distributed, mainly in temperate regions of the Northern Hemisphere and the flowers are insect pollinated. Many Liliaceae are important ornamental plants, widely grown for their attractive flowers and involved in a major floriculture of cut flowers and dry bulbs.

Some species are poisonous if eaten and can have adverse health effects in humans and household pets. A number of Liliaceae genera are popular cultivated plants in private and public spaces.

Les lys ou lis sont des plantes herbacées de la famille des Liliaceae appartenant au genre Lilium. Répartition, habitats[modifier | modifier le code] Ces plantes à bulbe sont originellement présentes dans les zones tempérées de l'hémisphère nord. On les trouve principalement en Europe, mais aussi en Asie, de l'Inde jusqu'au Japon et aux Philippines.

Leur aire de répartition couvre également les États-Unis et le sud du Canada. Les espèces du genre Lilium sont habituellement adaptées aux milieux forestiers, souvent montagneux, ou plus rarement aux milieux dégagés (prairies). De nombreuses variétés sont cultivées et ornent les jardins du monde entier. Description[modifier | modifier le code] Leurs grandes fleurs à six tépales (3 pétales et 3 sépales identiques), souvent parfumées, peuvent arborer des couleurs vives, blanches, jaunes ou rouges, avec parfois des motifs colorés. Biologie, floraison[modifier | modifier le code] Pétale avec pollen. WIKIPEDIA – Lilium. Lilium (members of which are true lilies) is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers.


Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the temperate northern hemisphere, though their range extends into the northern subtropics. Many other plants have "lily" in their common name but are not related to true lilies. Virus Res. 2000 Nov;71(1-2):23-32.
