Of the more nondescript plants most interesting - it certainly kinds of mimosas , exhibiting sensitivity . The birthplace of most of mimosas - South America , but one kind , Mimosa pudica, spread across Africa and Asia , so that now in many areas of eastern and western tropical mimosa is a common weed , often completely spanning the earth with his delicate foliage. If mimosas overgrown with more or less extensive plot of land , then walking on it is accompanied by a very peculiar phenomenon . At each step all the mimosas at a known distance from walking suddenly , as if struck palsy cringe from such fields of mimosas fallen formed like path a few feet wide, stands out due to the fact that somknuvshiesya leaves are distinguished by their color. Explanation of this phenomenon is given by botanists , not too intelligible , and the value and use it all the more mysterious. After all of the approximately 200 species of the genus Mimosa few gifted any appreciable sensitivity, and throughout the plant kingdom there are very few plants that have had more than a trace of her . It is very likely that these sensitive plants as low shrubs with delicate foliage could be destroyed by grazing animals , from which they may be , makes the ability to suddenly slam the touch threatening their mouths . The fact that one species is so widely spread in the tropics as a weed , shows , apparently , some of its superiority over most tropical grasses . Yet it remains unclear that although most sensitive species to some extent, mimosa and prickly , so simple and common method of protection , the development of strong spines and thorns , as it proved insufficient, and the plant was forced to resort to such a strange method of self-defense , in which it like pretending to be dead , it gives the impression of having his sensitivity and ability to consciously move.
