%X In this paper, the chromosome number and karyotype of the small genus, Po-randra Hong (Commelinaceae) , are reported for the first time. The two species, P. ramosa Hong and P. scandens Hong, were found to have the same chromosome number 2n = 36 and quite similar karyotypes, which could be formulated as 2n= 36 = 4m 26sm 6st (2sat). Having the same original basic chromosome number x = 9 and very similar chromosome morphology, Porandra might be closely related to Amischotolype and Coleotrype, as indicated also by their similar gross - morphological characters.
