摘 要 ：通过调查,对Swietenia mahagoni的后选模式、S.macrophylla的主模式与中国分类学文献（如《植物分类学报》、《广州植物志》、《中国高等植物图鉴》、《云南植物志》、《广东植物志》、《中国植物志》和《中国高等植物》）的S.mahagoni作比较，证实中国分类学文献将S.mahagoni和S.macrophylla相混，上述分类学文献中的S.mahagon是S.macrophylla King。桃花心木(S.mahagoni (L.) Jacq.)的羽状复叶及小叶较短，小叶长度绝不超过10 cm，果卵球形，长度绝不超过15 cm；而大叶桃花心木(S.macrophylla King)的羽状复叶及小叶较长，总有一部分小叶的长度超过10 cm，果长卵球形，长12~22 cm。

Abstract:Based on the lectotype of Swietenia mahagoni and the holotype of S.macrophylla, the status of those species as cited in Chinese taxonomic literature, such as Acta Phytotaxonomica Sinica, Flora of Guangzhou, Iconographia Cormophytorum Sinicorum, Flora Yunnanica, Flora of Guangdong, Flora Reipublicae Popularis Sinicae and Higher Plants of China, the name S.mahagoni has been misapplied in above-mentioned Chinese taxonomic literature and should be Swietenia macrophylla King. Swietenia mahagoni (L.) Jacq. has leaflets less than 10 cm long and oval fruits less than 15 cm long; S.macrophylla King has always a quantity of leaflets more than 10 cm long and club-shaped fruits 12-22 cm long.
