''Drosera quartzicola'' is a species in the carnivorous plant genus ''Drosera'' and is endemic to the Serra do Cipó in central Minas Gerais state in southeastern Brazil. It is perennial plant that produces leaves, long, in a rosette that is sometimes on a short stem about tall. It is found growing in campo rupestre vegetation along with ''D. tentaculata'' and ''D. chrysolepis''. It is typically found growing in silica sands surrounded by white quartz gravel, which is the origin of the specific epithet ''quartzicola''. ''Drosera quartzicola'' grows in drier habitats than other ''Drosera'' species and flowers earlier in the wet season from January to February. It superficially resembles ''D. schwackei'', but it is more closely related to ''D. camporupestris'', ''D. graminifolia'', and ''D. chrysolepis''.〔Rivadavia, F., and P. M. Gonella. 2011. ''Drosera quartzicola'' (Droseraceae), a new and threatened species from the Serra do Cipó, Brazil. ''Phytotaxa'', 29: 33–40.〕 Of the ''Drosera'' found in Brazil, ''D. quartzicola'' is the rarest, consisting of only four known populations of about 300 individual plants as of its description in 2011. These populations are at an elevation of and are either at the edge of the Serra do Cipó National Park or outside the boundary of the protected area. Some of the small populations are also in areas of occasional to frequent disturbance by humans and cattle. Because of these factors, the authors proposed listing this new species as critically endangered under the International Union for Conservation of Nature (IUCN).〔 ''Drosera quartzicola'' was first collected in the early 1990s and deposited as an herbarium specimen at the Universidade de São Paulo Herbarium, but it was not immediately recognized as a new species. Rivadavia and Gonella made the rediscovery of the new taxon in 1996 but did not formally publish their findings until 2011 in the journal ''Phytotaxa''.〔 == See also == *List of ''Drosera'' species *Taxonomy of ''Drosera'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Drosera quartzicola」の詳細全文を読む スポンサード リンク
