About

The lily family, Liliaceae, consists of about 15 genera and 610 species of flowering plants within the order Liliales. They are monocotyledonous, perennial, herbaceous geophytes, often growing from bulbs although some have rhizomes. The leaves are linear in shape, with their veins usually arranged parallel to the edges, single and arranged alternating on the stem, or in a rosette at the base. The flowers are large with six colored or patterned petaloid tepals arranged in two whorls of three, six stamens and a superior ovary. The fruit can be a berry or capsule, with seeds dispersed by animals or wind, respectively.

How this plant poisons

While members of the Liliaceae s.s. have been used as food sources in humans, the bulbs of some species are poisonous to household pets (bulb toxicosis) if eaten and may cause serious complications, such as kidney failure in cats from Lilies, particularly Lilium longiflorum (Easter Lily). Dogs may develop less serious effects such as gastrointestinal problems and central nervous system depression. Most Fritillaria (e.g. F. imperialis, F. meleagris) bulbs contain poisonous neurotoxic alkaloids such as imperialin (peiminine), which may be deadly if ingested in quantity, while other species such as Fritillaria camschatcensis and Fritillaria affinis are edible. Tulips can cause skin irritation due to the presence of tuliposides and tulipalins, which are also found in the flowers, leaves and stems of Fritillaria. These are also toxic to a variety of animals.
