Rhododendron vaseyi, the pinkshell azalea,[4] is a species of flowering plant in the heath family Ericaceae. It is endemic to the Appalachian highlands of North Carolina.

Description

Rhododendron vaseyi is a deciduous shrub that grows up to 5 metres (16 ft) in height. The large flowers are pink and begin to bloom in April.[5]

Taxonomy

Rhododendron vaseyi was named and described by the American botanist Asa Gray in 1880.[6] The type specimen was collected in 1878 by George Richard Vasey,[7][8] son of botanist George S. Vasey. Gray named the species in honor of both father and son.[9]

Distribution and habitat

Rhododendron vaseyi is endemic to the Appalachian highlands of North Carolina in widely scattered locations. While there is a main center of distribution west of Asheville, there is also a large population on Grandfather Mountain, in the northwestern corner of the state.[2]

In the wild, this species grows in acidic moist and wet substrates near bogs and streams. It may occur alongside other types of Rhododendron, such as Rhododendron maximum. The understory is made up of many ericaceous species, such as Vaccinium spp. and Leucothoe editorum.[2] The plant can often be found in areas of the forest that have been recently cleared by logging operations.[10]

Conservation

Threats to Rhododendron vaseyi in the wild include destruction of habitat as land is converted to residential use, and poaching.[10]
