''Dodecatheon poeticum'' is commonly known as the poet's shooting star or the Narcissus shooting star. ''D. poeticum'' is a species of the genus ''Dodecatheon'' which is native to the states of Oregon and Washington in western North America. The genus ''Dodecatheon'' contains herbaceous flowering plants and is also a part of the primrose family Primulaceae. This plant has basal clumps of leaves and drooping flowers that occur at the apex of tall stems that rise from where the leaves join. ==History== ''D. poeticum'' was discovered by Dr. Louis F. Henderson of the University of Oregon in 1930. The discovery of this flower was made shortly after the discovery and identification of another plant from the same genus, ''Dodecatheon dentatum''. During the initial classification of the white colored ''D. dentataum'', botanists must have overlooked the purple pink ''D. poeticum''. Unlike the other species, information regarding the classification of ''D. poeticum'' was rare and many botanists claimed texts describing the diversity of flora in northwestern America rarely mentioned its abundance. Due to recent research and classification efforts, ''D. poeticum'' now has volumes of information regarding its features and is commonly found in nature and nurseries alike. ==Morphology== ''D. poeticum'' has erect stems and leaves. It arises from a root with many fibrous fibers which become fleshy during flowering time. All the flower parts above ground except the corolla are glandular and are covered by fine short hairs.〔 The leaves are grouped in alternate, opposite or whorled distributions. The leaves are entire to lobed in shape and are 5 to 12 centimeters in length. The leaves vary from narrowly egg shaped with the widest section below the middle to narrowly lance shaped. The leaf margins on ''D. poeticum'' are more finely toothed than on ''Dodecatheon dentatum''. ''D. poeticum'' has petioles that are about the same length as the leaves or shorter. The petals are unusual and curved often in bright hues of pink to lavender. The corolla is five lobed similar to ''Dodecatheon dentatum'' while many other species of ''Dodecatheon'' only contain four. The flower, composed of both stamens and pistils is deep purple. The corolla is yellow in color at the base and dark purple at the top. The flowers droop slightly.〔 As the plant continues to age and eventually die, the seed capsules turn completely erect, ripen and discharge their seeds for new plants during the next growing season. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dodecatheon poeticum」の詳細全文を読む スポンサード リンク
