Abstract
We provide a molecular phylogenetic analysis of the Laelia alliance based on sampling of 20 of an estimated 24 species,
and seven plastid regions plus nrITS 1 & 2 analyzed using maximum parsimony, maximum likelihood, and Bayesian
inference. Furthermore, we used coded indels to evaluate their effect on the phylogenetic relationships and / or support values
(bootstrap and posterior probabilities). Our results confirm the existence of two clades, the long known Laelia (endemic to
M?xico at middle to high elevations) and Schomburgkia (a more widely distributed taxon). Both clades were strongly supported
by PP values and moderate BS; thus, we preferred to recognize them as separate genera with a reappraised morphology
and taxonomic delimitation. The inclusion of coded indels in the analyses was of great utility; we could identify the probable
hybrid origin of L. gouldiana and L. halbingeriana. We propose new combinations to accommodate the taxonomic changes
resulting from our study. We transfer L. anceps subsp. anceps, L. anceps subsp. dawsonii, L. aurea, L. mottae, and L. rubescens
to Schomburgkia, with the second taxon elevated to species level; the molecular evidence together with previous published
works on the morphology, phenology and geography of the group support these decisions. Lastly, the recently described genus
Encabarcenia is considered as a synonym of Schomburgkia and, as a result, a new combination is proposed.
