Resumen:
A new species, Laelia halbingeriana, and a new natural hybrid, Laelia
xoaxacana, both from the Sierra Madre Oriental in northern Oaxaca,
Mexico, are described and illustrated. Laelia halbingeriana is similar
to L. superbiens, from Chiapas through Nicaragua, differing in the
proportionately shorter, stouter pseudobulbs, low, entire, distally
white keels of the labellum and obscurely bilobed anther. Laelia
xoaxacana is applied to a hybrid swarm between L. halbingeriana and
sympatric L. anceps. The hybrid can be distinguished from L.
halbingeriana by the distichous (vs. spiral) raceme and the spreading
petals oriented vertically (vs. distinctly arcuate and oriented
horizontally), and from L. anceps in the stouter plants with two-leaved
pseudobulbs and the proportionately narrower, waved sepals and petals.
