The Amorphophallus genus is a perennial herb which belongs to the family Araceae. There are more than 170 species in this genus, which is widely distributed in tropical and subtropical areas. As a kind of food and medicine Amorphophallus has been used for more than 2000 years in China. Because of the high content of konjac glucomannan (KGM) and dietary fiber, it has attracted more attention worldwide. In this article, the DNA contents of A. konjac , A. albus and A. bulbifer in China, A. albus , A. paeoniifolius and A. muelleri in Indonesia were estimated by using flow cytometry. In the samples of China, the DNA contents were 12.95 ± 0.73 pg/2C in A. konjac , 10.51 ± 0.05 pg/2C in A. albus and 17.61 pg/2C in A. bulbifer , and for Indonesia, 14.16 ± 0.48 pg/2C in A. albus (flowering), 8.49 ± 0.2 pg/2C in A. paeoniifolius and 17.84 ± 1.46 pg/2C in A. muelleri were used. Interspecific variation was found significantly ( P
