被子植物起源问题被达尔文称为一个厌恶之谜 ,至今尚未解决。根据现代和化石植物的形态学研究 ,最早的被子植物被认为像尼藤类那样在两性生殖枝上有苞片和次生生殖枝 (假花说 /花序说 )或像本内苏铁那样在两性生殖枝上有苞片和生殖孢片 (真花说 )。最近基因分子学研究结果认为
The origin of the angiosperms was described by Darwin as a mystery of aversion that has so far not been resolved. According to the morphological studies of modern and fossil plants, the earliest angiosperms were considered to be bracteoles and secondary reproductive branches (pseudophyceae / inflorescences), as in the genus Nepenthes, or both sexes Reproductive branches bracts and genital spores tablets (true flowers that). Recent gene molecular study concluded that
