Synopsis of <em>Chionanthus</em> (Oleaceae) from Colombia and neighboring countries, with description of a new species

Abstract

A synoptic review of Chionanthus species (Oleaceae) from Colombia and neighboring countries is presented, in which new information, taxonomic and chorological, is disclosed, and a new species, Ch. vargasii, from the Central Cordillera of Colombia. This species resembles Ch. abriaquiensis, but has coriaceous leaves, with shorter petioles and woolly domatia along the veins of the underside, and shorter inflorescences. Chionanthus guianensis and Ch. panamensis are cited for the first time in Colombia and the known distribution in Colombia of Ch. compactus, Ch. implicatus, and Ch. pubescens is extended. In addition, the reviewed material of Ch. avilensis, Ch. colonchensis, Ch. ligustrinus, and Ch. wudackii, all present in neighboring countries, is also commented. Finally, a key is included to facilitate the identification of the species of the north of South America.

Priogymnanthus colombianus (Oleaceae), a new species and first record of genus to Colombia

“…Historically, Oleaceae (Lamiales) were only represented in Colombia by two native species of the Pantropical genus Chionanthus Linnaeus (1753: 8). In recent years, new records for two cultivated species and descriptions of three new species in 2016, increased this number to seven, all in the same genus (Bernal 2015, Fernández-Alonso & Cogollo 2016, Fernández-Alonso & Cogollo 2017. The new species of Priogymnanthus P.S.…”
