In 1959 botanists Harriet Barclay and Pedro Juajibioy collected some samples
of a woody shrub from the Páramo de Macotama above the valley of Río Ancho in
the Sierra Nevada de Santa Marta in northern Colombia and sent them to the South American mountain plant specialist José Cuatrecasas for identification. This was identified as a member
of the Aster tribe Gnaphalieae, but at the time the taxonomy of this group was
poorly understood, and he was not able to make any more detailed designation.
In a paper published in the journal PhytoKeys on 5 February 2015, Harold Robinson of the Department of Botany at the National Museum of Natural History
formally describes Barclay and Juajibioy’s material as new species in the genus
Chionolaena.
The new species is named Chionolaena barclayae,
presumably in honour of Harriet Barclay, though no explanation is given. It is
a small woody shrub reaching about 20 cm high, producing pinkish or reddish
flowers. It is known only from Barclay and Juajibioy’s material, collected on
high rocky outcrops in the Sierra Nevada de Santa Marta.

Living in limestone habitats requires special adaptations from plants; as such areas tend to have thin layers of alkaline soil over porous bedrock, leading to frequent periods of aridity. Since exposed limestones are most frequently found in upland areas surrounded by areas of lowlands with different environmental conditions, the...
