Approximately one third of its flora is endemic. The Muscari muscarimi which belongs to the Liliaceae family is one of its most prominent endemic geophyte plants which originates in southwestern of Turkey where it is found in rocky places like Ermenek, Ba？yayla （Büyükkarap？nar village）, Sar？veliler. This species is the most sweetly scented member of the Liliaceae family, having something of the musk scent. Also, this plant locally is used in traditional medicine as antirheumatic, stomachic, diuretic and expectorant. In addition to this, it has also been used as food for humans and animals, ornamental plants in gardens. Morphologically, it has 3-6 linear-lanceolate, grayish-green leaves per plant and bulbs of 2-4 cm in diameter with thick fleshy perennial roots which delve down into the rocky ground of their natural habitats. The chemical is composed of polysaccharides, homoisoflavanons, glycosides etc. Main components of M. muscarimi were identified as （E）-β-ocimene （t-36%）, methyl salicylate （1-21%）, E-methyl isoeugenol （4-22%） and benzyl benzoate （7-56%）. The picking up of the plant bulbs from their natural habitats is prohibited, in accordance with international agreements for the protection of endangered geophytes. The overly habitat destruction in native growing area threatened the existence of the species categories. It is known that in vitro bulblet production in Muscari muscarimi is low. This is difficult for its cultivation in native Ermenek area districts. Recent works show that the culturing immature Musari muscarimi embryos on different growth media could be considered as a useful method for in vitro propagation. As a result, the geophytes, such as M. muscarimi, are eligible widely for perfume production and in the pharmaceutical industry as well as for ornamental flowers. Because of this plant economic importance, bulbs growing and cultivation in their natural habitats could be discussed in this study.展开更多
