White doves flying in the sun - Chinese Dove Tree
（國家一級重點保護植物）
(First-Grade State Protection Plant)
珙桐（拉丁學名：Davidia involucrata Baill）為落葉喬木。可生長到15~25米高，葉子廣卵形，邊緣有鋸齒。本科植物只有一屬兩種，兩種相似，只是一種葉面有毛，另一種光葉珙桐是光面。色花奇美，是1000萬年前新生代第三紀留下的孑遺植物，在第四紀冰川時期，大部分地區的珙桐相繼滅絕，只有在中國南方的一些地區幸存下來，成為了植物界今天的“活化石”，被譽為“中國的鴿子樹”，又稱“鴿子花樹”、“水梨子”，野生種只生長在中國西南四川省和中部湖北省和陜西省周邊地區。
Chinese Dove Tree (Scientific Latin Name: Davidia involucrata Baill) is a deciduous arbor, 15–25m high and has wide ovoid leaves with jagged edges. There are only one genus and two species in this family, both of which are similar except that one has a hairy leaf and the other is a glossy leaf. Its flowers are especially beautiful. It's a relict from the Cenozoic Tertiary Period 10 million years ago.In the Quaternary Glacial Period, Davidia involucrata became extinct in most areas, and only in some areas of southern China, it survived and became the "living fossil" of the plant kingdom, known as the "Chinese Dove Tree", "Dove Flower Tree" and "Water Pear Tree".The wild species only grows in Sichuan Province in southwest Chinaand the surrounding areas of Hubei Province and Shaanxi Province in central China.
