Abstract

Morphological and anatomical investigations confirm the reduction of Schickendantzia Pax to Alstroemeria L. Schickendantzia pygmaea (Herb.) Speg., a small herb growing in the Andean mountains, 3500-4400 m above sea level, was first described in the genus Alstroemeria. Particularly valuable in determining the correct taxonomic position are: the presence of axile placentation, a trilocular ovary, two inner usually spotted, upper tepals, a rhizome with some fleshy-starchy white roots, a six-ribbed loculicidal capsule, umbonate towards the apex with explosive dehiscence, light brown and globose seeds, the outer integument of seed coat dry, with a sculptured surface, ballistic dispersal and pollen grains with striato-reticulate sexine. Therefore, the family Alstroemeriaceae Dumort. should be considered as composed of three genera, Alstroemeria L., Bomarea Mirb. and Leontochir Phil.
