× Beruladium Procurrens
× ''Beruladium procurrens'' is an Hybrid (biology), intergeneric hybrid plant in the Apiaceae, umbellifer family (Apiaceae); the result of hybridisation between ''Berula erecta'' (lesser water parsnip) and ''Apium nodiflorum, Helosciadium nodiflorum'' (fool's water cress). Discovery In July 1979 S. M. Walters, Max Walters collected an unidentified plant from Chippenham Fen and Snailwell Poor's Fen, Chippenham Fen, Cambridgeshire, England; it resembled ''H. nodiflorum'', but grew as a floating mass in a fen ditch with small, Peduncle (botany), pedunculate umbels rising above the water surface. Later that year, the specimen was exhibited as a living plant at the annual Botanical Society of Britain and Ireland, BSBI exhibition meeting at the British Museum in London. An initial putative determination of ''H. repens'' was made, but as the plants were found to produce poor pollen and did not develop ripe fruits a hybrid origin was deemed more likely, possibly Helosciadium x longiped ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
