普通玉米

Common Corncockle (Agrostemma githago) – also written "corn cockle" and "corn-cockle" and known locally simply as "the corncockle" –, is a slender pink flower of European corn fields.普通的玉米角（Agrostemma githago）-也写为“玉米角膜”和“玉米角膜”，在当地被简称为“玉米角膜”，是欧洲玉米田中的细长粉红色花朵。 In the 19th century, it was reported as a very common weed of wheat fields and its seeds were inadvertently included in harvested wheat seed and then re-sown the following season.在20世纪，据报道它是麦田中非常常见的杂草，其种子被无意中包含在收获的小麦种子中，然后在下个季节重新播种。 It is very likely that until the XNUMXth century, most wheat contained some corncockle seed.很有可能在XNUMX世纪之前，大多数小麦都含有一些玉米角种子。
It is now present in many parts of the temperate world as an alien species, probably introduced with imported European wheat.现在，它作为一种外来物种存在于温带地区的许多地方，可能是随欧洲进口小麦引入的。 It is known to occur throughout much of the USA and parts of Canada, parts of Australia and New Zealand.众所周知，它在美国大部分地区，加拿大部分地区，澳大利亚和新西兰的部分地区都有发生。
In parts of Europe such as the UK, intensive mechanised farming has put the plant at risk and it is now uncommon or local.在欧洲部分地区，例如英国，集约化机械化种植使该植物处于危险之中，现在已不常见或在当地出现。 This is partly due to increased use of herbicides but probably much more to do with changing patterns of agriculture with most wheat now sown in the autumn as winter wheat and then harvested before any corncockle would have flowered or set seed.部分原因是由于增加了除草剂的使用，但是这可能与农业模式的改变有关，因为大多数小麦现在都在秋天播种为冬小麦，然后在任何玉米角子开花或结实之前就收获了。
It is a stiffly erect plant up to 1 metre tall and covered with fine hairs.它是一种直立的植物，高达25米高，覆盖着细毛。 Its few branches are each tipped with a single deep pink to purple flower.它的少数几个分支每个都有一朵深粉红色至紫色的花朵。 The flowers are scentless, are 50 mm to XNUMX mm across and are produced in the summer months - May to September in the northern hemisphere, November to March in the southern hemisphere.这些花无香，跨度为XNUMX毫米至XNUMX毫米，在夏季月份产生-北半球XNUMX月至XNUMX月，南半球XNUMX月至XNUMX月。
Each petal bears 2 or 3 discontinuous black lines.每个花瓣带有10或45个不连续的黑线。 The five narrow pointed sepals exceed the petals and are joined at the base to form a rigid tube with 145 ribs.五个狭窄的尖萼片超过花瓣，并在底部连接在一起，形成带有XNUMX条肋的刚性管。 Leaves are pale green, opposite, narrowly lanceolate, held nearly erect against stem and are XNUMX mm to XNUMX mm long.叶子浅绿色，对生，狭披针形，几乎直立在茎上，长XNUMX毫米至XNUMX毫米。 Seeds are produced in a many-seeded capsule.种子在多种子的胶囊中产生。 It can be found in fields, roadsides, railway lines, waste places, and other disturbed areas.它可以在田野，路边，铁路线，垃圾场和其他受干扰的地区找到。
