《群芳谱》记载说:“海棠有4种,皆木本。贴梗海棠,丛生,花如胭脂;垂丝海棠,树生,柔枝长蒂,花色浅红;又有枝梗略坚、花色稍红者,名西府海棠;有生子如木瓜可食者,名木瓜海棠。”其实,这4种“海棠”,并非同属植物。 “Qunfang spectrum” records, said: “There are 4 Begonia, are woody. Sticky Begonia, clusters of flowers such as rouge; hanging Begonia, tree life, soft sticks long pedicel, color light red; Slightly red color, the West House Begonia; have children such as papaya edible, name papaya Begonia. ”In fact, these four kinds of“ Begonia ”, not the same plant.
