Macrotomia bosbutooensis (Boraginaceae), a new species from Kyrgyzstan
The paper provides a description of a new species of Macrotomia from section Munbuya from Kyrgyzstan (Western Tian Shan). Genus Macrotomia is a small group of species of the Boraginaceae family distributed from the Himalayas to Asia Minor and southern Europe (Greece). The exact number of species in the genus is unknown, due to the fact that a number of names are critical, and this taxon itself is often considered part of the genus Arnebia. The new species is close to Macrotomia euchromos, the most widespread species in Middle Asia, but differs from it in corolla color, as well as in its distribution in a lower mountain zone, an earlier flowering and fruiting time. According to our data, the new species is endemic to the Bosbu-Too Mountains (Western Tian Shan) but can be found on the adjacent Atoynok Mt. Ridge.
