Vascular plant hybrids are numerous and constitute an important feature of our vegetation, but all too often they have been neglected by botanists. Some hybrids between native species are rare, sterile and ephemeral, but others reproduce vegetatively or by seed and have spread beyond the areas where their parents coexist.
Hybrid Flora of the British Isles provides detailed accounts of the 909 hybrids reliably recorded in the wild in the British Isles. Identification notes are provided for each of these hybrids, their habitats are outlined and detailed accounts of their distributions provided, with notes on the discovery of many hybrids. Novel maps illustrate the records of the commoner hybrids in relation to those of their parents. Known chromosome numbers are given for each hybrid and its parents, and information is provided on the hybrid's fertility/sterility and its capacity for vegetative reproduction.
