摘要：

A putative natural hybrid between Orchis laxiflora and O. morio (Orchidaceae) from southern Italy, formerly known as O. alata, was characterized both on morphological and molecular grounds in order to confirm its hybrid status and to trace its maternal lineage. The morphological characters of the putative hybrid showed intermediacy between those of the parent species, and restriction fragment length polymorphism (RFLP) analysis of a region of the nuclear ribosomal DNA confirmed its hybrid origin. Chloroplast DNA RFLP analysis indicated that O. morio provided the maternal genome.
