''Hylomecon vernalis'', also known as the forest poppy, is a poppy of the Far East, ranging from Manchuria to Japan. This poppy is a perennial that spreads via rhizomes, typically no taller than 30 cm. The pinnate leaves usually have five soft green leaflets, although three and seven occur as well, each with a shape ranging from lanceolate-oblong to rhombic, and a pattern of distinct teeth along the margins. The flowers are bright yellow 3.5-5 cm across, starting out bowl-shaped, then flattening out with age. Its typical habitat is moist shaded woodland, growing in accumulated humus. Although generally considered a monotypic genus, the species is somewhat variable, and several variations have been named as separate species. == References == * Christopher Grey-Wilson, ''Poppies'' (Portland: Timber Press, 2000) ISBN 0-88192-503-9 pp. 40-41 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「Hylomecon」の詳細全文を読む スポンサード リンク
