Abstract

GONZALEZ, Favio  and  PABON-MORA, Natalia. First reports and generic descriptions of the achlorophyllous holoparasites Apodanthaceae (Cucurbitales) of Colombia. Actu Biol [online]. 2014, vol.36, n.101, pp.123-135. ISSN 0304-3584.

The Apodanthaceae (Cucurbitales) are one of the 12 parasitic clades of flowering plants and the only holoparasitic family with a vegetative phase entirely endophytic, growing primarily on Fabaceae and Salicaceae stems. The two genera of the family, Apodanthes and Pilostyles, are broadly distributed in Colombia, although they remain extremely under-collected and poorly known. Based on field and herbarium work, and a review of the literature, we provide detailed generic-level descriptions of the family. We also update the records of the family in Colombia and discuss the homology and taxonomic implications of floral characters such as perianth scales, pollen sacs, and the central column. Finally, we provide photographic records of Colombian Apodanthaceae, and some guidelines for properly collecting these plants.

Keywords : Apodanthaceae; Apodanthes; Cucurbitales; Colombian flora; parasitic flowering plants; Pilostyles.
