	abstract = {Isoetes sinensis is a rare and endangered plant in wetlands of southeastern China. Previous studies have reported the chromosome number, geographic distribution, and ecology of this Asian endemic, but there has not been an analysis of diagnostic characters associated with the sporophylls of I. sinensis in China. Therefore, morphological and anatomical variation of sporophylls in the three known Chinese populations of I. sinensis were evaluated and compared. The variation found is discussed in relation to the present taxonomy of I. sinensis.},

	abstract = {Micromorphological characters of mega- and microspores of five Iso{\"e}tes species from China were observed under scanning electron microscope (SEM). Megaspores of I. hypsophila have a levigate ornamentation, and are 358 μm in diameter (mean, n=30), microspores of this species have a gyrus ornamentation, and are 22 μm in length (mean, n=30); megaspores of I. yunguiensis have a cristate-reticulate ornamentation, with a size of 390 μm in diameter (mean, n=30), while microspores nearly smooth with some fine granulates, and with a size of 22 gm in length (mean, n=30); megaspores of I. taiwanensis are tuberculate and 312 μm in diameter (mean, n=30), echinate microspores are 24 μm in length (mean, n=30); cristate megaspores of I. sinensis are 409 μm in diameter (mean, n=30), and echinate microspores are 28 μm in length (mean, n=30); megaspores of I. orientalis have a cristate-reticulate ornamentation, with diameter of 420 μm (mean, n=30), microspores of this species have an echinate-tuberculate ornamentation with a size of 34 μm in length (mean, n=30). Based on the morphological characters of spores and chromosome numbers among taxa, it was found that mean spore size in each species of Iso{\"e}tes generally reflected the ploidy level. I. hypsophila, I. yunguiensis and I. taiwanensis, with smaller mean spore size, are diploidy with 2n=22; I. sinensis (2n=44) and I. orientalis (2n=66), with larger mean spore size, are polyploidy. The spore morphology of Iso{\"e}tes still plays an important role in identification and classification of Iso{\"e}tes from China.},
