The chromosome numbers, meiotic course with pollen fertility and pollen size measurement of five species of <I>Pedicularis</I> were assessed: <I>P. gracilis</I>, <I>P. hoffmeisteri</I>, <I>P. pectinata</I> spp. <I>bipinnatifida</I>, <I>P. porrecta</I> and <I>P. punctata</I>. All the five species studied were diploid with 2n=16. The chromosome counts were the first report for <I>P. pectinata</I> spp. <I>bipinnatifida</I>, <I>P. porrecta</I> and <I>P. punctata</I>. Also the phenomenon of cytomixis was reported in these three species. All the chromosome counts reinforced x = 8 as the basic chromosome number for them.
