Papaver Paczoskii
''Papaver'' is a genus of 70–100 species of frost-tolerant annuals, biennials, and perennials native to temperate and cold regions of Eurasia, Africa and North America. It is the type genus of the poppy family, Papaveraceae. Description The flowers have two sepals that fall off as the bud opens, and four (or up to six) petals in red, pink, orange, yellow, or lilac. There are many stamens in several whorls around a compound pistil, which results from the fusion of carpels. The stigmas are visible on top of the capsule, and the number of stigmas corresponds to the number of fused carpels. The ovary later develops into a dehiscing capsule, capped by the dried stigmas. The opened capsule scatters its numerous, tiny seeds as air movement shakes it, due to the long stem. The typical ''Papaver'' gynoecium is superior (the flower is hypogynous) with a globular ovary. The style is characteristically absent for the type species opium poppy, and several others, although those with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papaver Setigerum
''Papaver setigerum'', common name poppy of Troy or dwarf breadseed poppy, is a herbaceous annual plant of the family Papaveraceae. This plant is closely related to and sometimes treated as a subspecies of opium poppy (''Papaver somniferum''). In fact it produces a very small amount of morphine alkaloids. However, ''P. somniferum'' is diploid (n=11) and ''P. setigerum'' is tetraploid (n=22) with twice the number of chromosomes. So it cannot be considered the wild ancestral species of the opium poppy.C. G. Farmilo, H. L. J. Rhodes, H. R. L. Hart and, H. TaylorDetection of Morphine in Papaver setigerum DC/ref> Etymology The genus name is derived from the Latin word ''papaverum'' meaning “poppy”, while the specific name ''setigerum'' derives the Latin "saetiger" meaning “bristly” for the short bristle on the top of the lobes of its leaves.Pignatti S. - Flora d'Italia – Edagricole – 1982.
