Tectonic Development

Geologic maps, seismic lines, and data from a dry exploration well were used to develop a new structural model for a segment of the eastern foothills of the Eastern Cordillera of Colombia, emphasizing the role of salt tectonics. Milestones in the deformation history of the Guatiquía foothills were studied by sequential section restoration to selected steps. Uncommon structural geometries and sparse salt occurrences were interpreted in terms of a kinematic evolution in which Cretaceous salt migration in extension produced a diapiric salt wall, which was subsequently welded during the main episodes of the Andean compression, when the salt wall was squeezed generating a large overturned flap. Salt-weld strain hardening resulted in breakthrough thrusting across the overturned flap in late deformation stages. We have evaluated a pattern of salt tectonics previously unrecognized in the foothills thrust belt, which may be significant in other parts of the external Colombian Andes.

Two New Species

Two new species, Passiflora splendida and P. quinonesiae of the section Colombiana from the Andes of Cundinamarca Department (Colombia Eastern Cordillera) are described and illustrated. Passiflora splendida is morphologically similar to P. cremastantha of the series Leptomischae, but can be distinguished by its linear stipules, petioles up to 1.8 cm long, lance-ovate leaves (6–8.5 × 2.5–3.3 cm), flowers with a diameter of 9–11 cm long, sepals and petals with intermediate disposition, both longer than the floral tube, floral tube of 3.2–4.5 cm long and fusiform ovary. Passiflora quinonesiae is similar to the species of series Colombianae, most closely related to P. cuatrecasasii and P. lanata. It differs from P. cuatrecasasii by its terete stem, size of the leaves 4.4–15 × 10.3 cm, elliptic bracts and floral tube 5.2–6 cm long. It differs from P. lanata by its ovate leaves, bracts halfway down the floral tube, elliptical sepals and petals, and elliptical ovary. In addition, a taxonomic key to section Colombiana ser. Colombianae and Leptomischae for Colombia is included and information about the ecology, distribution, and conservation status of P. splendida and P. quinonesiae are discussed.

Quercus Humboldtii

We praise the authors for their work, and for the lyric title of their paper. We give a concise sketch of the present level of understanding of Quercus forest in Colombia. We identify the shortcomings in this published paper. We improve the relevance of this paper about Quercus as well as for future phylogenetic investigations other montane forest taxa to be framed in the rapidly improving palaeoecological understanding of the Northern Andes.
