	abstract = {The somatic chromosome number of three Japanese species of Isoetes, I. asiatica, I. japonica and I. sinensis, was determined in 199 individuals from 49 populations. The chromosome number of I. asiatica was 2 n=22, confirming previous reports. However, I. japonica and I. sinensis displayed a diversity in chromosome number. Six cytotypes, 2 n=66, 67, 77, 87, 88 and 89, were found in I. japonica; 2 n=67, 87, 88 and 89 are new counts in the genus Isoetes. The plants with 2 n=66 were the most frequent (72\% of total individuals examined) and were distributed throughout Honshu and Shikoku. The plants with 2 n=88 occurred in western Honshu and a limited region in northeastern Honshu where the plants with 2 n=77 were also found. In contrast, four cytotypes, 2 n=44, 65, 66 and 68, were found in I. sinensis. The chromosome numbers of I. sinensis were reported here for the first time. The plants with 2 n=44 occurred only in Kyushu, while the plants with 2 n=66 were found throughout a large area of western Japan. {\textcopyright} 1994 The Botanical Society of Japan.},

	abstract = {Iso{\"e}tes iapygia from the Apulia region (southern Italy) is described as a new species and illustrated. It differs in several characters from the other Mediterranean Iso{\"e}tes species, but has some intermediate characteristics similar to terrestrial and amphibious Iso{\"e}tes. I. iapygia is similar to the amphibious species for the lack of phyllopodia, even if it has scales; it is similar to terrestrial species for the complete velum and tuberculate macrospores. A completely unique character is represented by the two air chambers. Its habitat is on limestone rocks, in temporary pools. {\textcopyright} 2010 Societ{\`a} Botanica Italiana.},
