| Abstract: | BATEMAN, R. M. & FARRINGTON, O. S., 1989. Morphometric comparison of populations of Orchis sitnia Lam. (Orchidaceae) from Oxfordshire and Kent. Univariate and multivariate morphometric analyses of Orchis simia Lam. from its two remaining naturally-founded populations in Britain (Goring, Oxfordshire and Faversham, Kent) reveal only minor morphological differences between the populations and suprisingly low levels of intra-population variation. This probably reflects recent founding from Continental seed at Faversham and penecontemporaneous, human-induced, catastrophic contraction of the gene pool at Goring. The apparently restricted gene pools of these populations may adversely effect their long-term survival. |
