オオベニウチワの名前
オオベニウチワの和名は大きな紅色の団扇のような仏炎苞に由来。英名も羽を広げたフラミンゴのように見えるからです。ラテン語の属名アンスリウムは「尾のような花」という意味で肉穂花序に由来。種小名アンドレアナムはフランスの造園家エドゥアール・アンドレへの献名です。

Flamingo Flower
Flamingo Flower is a perennial plant of the Araceae family. It is distributed from Ecuador to Colombia in South America and grows wild in highland tropical rainforests. It was introduced to Japan during the Meiji period and is grown indoors. It is characterized by a heart-shaped flower-like spathe and a spadix that resembles Pinocchio’s nose. In floriculture, it is known by its Latin genus name, Anthurium.
The Japanese name of Flamingo Flower means “large red fan” and comes from the spadix. The English name comes from the fact that it looks like a flamingo with its wings spread. The Latin genus name Anthurium means “tail-like flower” and comes from the spadix. The specific name andreanum is a tribute to the French landscape gardener Édouard François André.
The leaves of the Flamingo Flower are shiny and heart-shaped. They have long petioles and grow spirally at the base. The flower-like part is the spathe, which is shiny and heart-shaped. Meanwhile, the rod-shaped part in the middle is the spadix, which bears hermaphroditic florets densely. The florets have female and male phases, and different plants pollinate each other. After flowering, they produce fleshy berries.
Flamingo Flower contains toxic calcium oxalate. The needle-shaped crystals cause inflammation when they come into contact with the skin or mucous membranes, and if ingested accidentally, they can cause vomiting, and if the condition worsens, they can cause airway obstruction and convulsions. Particular care should be taken with dogs and cats, whose oral cavity is alkaline. This is because the needle-shaped crystals are less likely to break down, which can lead to serious illness.
