Fig. 2. Parts of the Ophrys flower of characters as a result of our participation in a previous similar investigation (SAPSÁL 1985), in which a methodological discussion is incorporated. All eleven characters were registered in each plant in order to use the data for a multivariate analysis. Furthermore, the characters were observed uniformly on the uppermost open flower in order to establish a basis for comparative judgement, because many of the features change during blooming. The quantitative characters are as follows: 1. Length of the plant, i.e. length of the flowering stem stretched out from soil level to its apex (to 1 mm precision). 2. Number of flowers on the plant, including both the opened and withered ones and buds. 3. Length of the sepals along the chord between its base and top, measured on the lateral sepal to 0.5 mm precision. 4. Width of the sepals at its widest point, measured without rolling up its rolled edge, to 0.5 mm precision. 5. Length of the petals between its base and top, measured to 0.5 mm precision. 6. Length of the labelium from the upper edge of the zona basalis (from the stigma) to the end of the labelium, excluding the appendix (to 0.5 mm precision!. 7. Length of the horn on its internal side, from the juncture with the middle lobe of the labelium to the tip of the horn, measured to 0.5 mm precision. The following qualitative characters observed: 1. Colour of the sepals, which is a particularly variable feature. It was classified into four categories: white, pink, green, and greenish pink. Ignorance of the whole scale of the possible colours initially rendered registration and therefore, classification somewhat difficult. This situation, however, was eventually rectified by a careful scrutiny of the colour slides. 2. Colour of the petals was determined similarly. 3. Colour of the appendix varies from yellow to dark brown. A thorough inspection of the slides indicated three categories: yellow, brown and intermediate. 4. Shape of the appendix can range from the cut form to the tridentate (Fig. 3) into three classes
