Erzberger, Peter: Funaria muhlenbergii and Funaria pulchella (Funariaceae, Bryophyta) in Hungary

Useful, though not as important as the above-mentioned features, is also the length of the terminal cell of the leaf apex, a character that is excellently illustrated in SMITH (1978) as well as in CRUNDWELL and NYHOLM (1974). Another character mentioned by them is seta length; Hungarian material seems to fall within the ranges reported for British material (Table 1). Finally, the number of stomata per sporophyte proved to be a good discriminating character (Fig. 2). According to a sample of 6 specimens of each species, stomatal number (minimum - median - maximum) in F. muhlenbergii is (43-)72.5(-101), whereas in F. pulchella it is (19-)31(—

42). The difference is statistically significant (p < 0.005) according to the Mann-Whitney U-test (Z = -5.844). In Figure 3, the results of the present revision of Hungarian specimens according to the modern taxonomic concept of the F. muhlenbergii group are compared to the names found on the specimen labels that result from out-dated concepts. 30 specimens (81.1%) of the total of 37 specimens revised as F. muhlenbergii had been labelled F. dentata, but only 7 (18.9%) as F. mediterranea. On the other hand, 28 specimens (71.8%) of the total of 39 specimens revised as F. pulchella had been labelled F. dentata, and 11 (28.2%) as F. mediterranea. Although a slightly higher percentage of F. pulchella than of F. muhlenbergii had Fig. 2. Boxplot of stomatal number in Funaria muhlenbergii and F. pulchella.
