论枇杷属植物的形态变异式样及其地理分布

对枇杷属植物的地理分布及形态变异式样的研究表明，我国西南至缅甸北部是该属植物的现代分布中心，也是该属植物的原始中心；华南、中南半岛、喜马拉雅分别是不同变异中心或次生演化中心；该属植物在种的分布式样上表现出明显的东西和南北替代现象；种的地理成分可划分为3个类型和10个亚型；该属植物的形态特征与分布式样显示了热带、亚热带之间植物区系成分的过渡性。

On the Variation Patterns of Morphological Characteristics and Geographical Distribution of Eriobotrya (Rosaceae)

The geographical distribution and the morphological variation patterns of Eriobotrya werestudied. The results are as follows: 1. South-West Cl1ina to North Burma (upper Burma ) is thepresent abundance centre of Eriobotrya, perhaps is the original centre too; 2. South China, Indo-Chineand Himalaya is severally the different variation centre or the secondary evolutionary centres; 3. Thespecies substitutionism from South to North or East to West is particularly evident; 4. The speciesmay be divided into three area types and ten area subtypes; 5. The morphological variation patternsand the geographical dlstribution of Eriobotrya show floras consistency of tropical and subtropicalregions.
