Six Calypogeia species occurring in Poland (C. azurea, C. sphagnicola, C. muelleriana, C. suecica, C. integristipula, C. neesiana) were biometrically studied with respect to 49 morphological and anatomical characters (47 quantitative, 2 qualitative). All 268 samples used in the biometrical analysis were previously identified by isoenzyme analysis and the oil bodies were studied. Quantitative analyses of all the characters studied showed that all taxa of Calypogeia occurring in Poland are morphologically distinct and that morphological characters correlate with the results of the isoenzyme investigation and the oil body types. From among those studied a set of 15 diagnostic characters were selected by Wilks' lambda criterion. The studied species differ also by two qualitative characters: leaf apex and lateral margin of underleaf. Calypogeia integristipula in Poland can be distinguished, without any difficulty, from C. neesiana even in herbarium material. Comparision of plants belonging to C. neesiana, C. integristipula and C. muelleriana occurring in Poland with their type specimens by means of classification functions being computed for each species showed that plants occurring in Poland fit their types morphologically.
