Geography shapes the phylogeny of frailejones (Espeletiinae Cuatrec., Asteraceae): a remarkable example of recent rapid radiation in sky islands [PDF]
PeerJ, 2017 Background The páramo ecosystem, located above the timberline in the tropical Andes, has been the setting for some of the most dramatic plant radiations, and it is one of the world’s fastest evolving and most diverse high-altitude ecosystems.

A nomenclator for the frailejones (Espeletiinae Cuatrec., Asteraceae) [PDF]
PhytoKeys, 2012 The páramos and high Andean forests of the tropical Andes are largely dominated by frailejones (Espeletiinae Cuatrec., Asteraceae). These plants are ecologically and culturally essential for both ecosystems and local inhabitants.

Chemical Composition of the Essential Oil from Carramboa pittieri (Cuatrec.) Cuatrec. (Asteraceae) [PDF]
Natural Product Communications, 2008 The essential oil from the leaves of Carramboa pittieri (Cuatrec.) Cuatrec. was isolated by hydrodistillation, yielding 0.1%. The chemical composition was determined by GC-FID and GC-MS. Forty-one components were identified by comparison of their mass spectra with Wiley and NIST Library data. The major constituents of the oil were germacrene-D (28.9%),
