ABSTRACT: Sanso, A. M. 1996. The genus Alstroemeria (Alstroemeriaceae)
in Argentina. Darwiniana 34: 349-382.
The Argentine species of Alstroemeria L. are studied and a brief
nomenclatural history of the genera is given. The taxonomic treatment includes
keys to species, descriptions, synonyms, illustrations, ecological observations
and distribution maps. At present, 10 taxa are recognized and treated for
Argentina: Alstroemeria andina Phil. subsp. venustula Ehr.
Bayer, A. apertiflora Baker, A. aurea Graham, A. bakeri
Pax, A. isabellana Herb., A. patagonica Phil., A.
presliana Herb., A. pseudospathulata Ehr. Bayer, A. psittacina
Lehm. and A. pygmaea Herb. The probable occurrence in our country
of A. spathulata C. Presl and A. pallida Graham is pointed
out. A. inodora Herb. is a new synonym of A. psittacina Lehm.
A. bakeri and the name A. hassleriana are here lectotypified.
Morphological data of taxonomical value are discussed. The most important
interespecific differences are found in the floral characters. The presence
or absence of resupination in the leaf, the plant height and the characteristics
of the inflorescence are also of importance.
