Abstract

<br> Natural hybridization in Neotropical orchids is summarized, and the frequency of nothogenera in the subtribe Zygopetalinae is highlighted. A new nothogenus discovered in Costa Rica, formed by the cross between species of<br> Benzingia<br> and<br> Chondroscaphe<br> , is described, and the new nothospecies ×<br> Benzoscaphe stelleri<br> is described and illustrated. Putative parents, as well as their derivative hybrid, are compared through composite digital plates. Cues are offered about the pollination mechanisms of the putative parents, based on the morphology of the flowers and pollinaria, which possibly led to the formation of the natural cross between different genera.<br>
