INTRODUCTION
Since 2009, the records made by the National Institute of Agricultural Sciences (INCA) constitute an important contribution to the history of Cuban orchid hybridization, by publishing a group of hybrids for the first time in the Complete List of Hybrid Orchids of Sanders, Royal Horticultural Society of England and in the Descriptive Catalog of Varieties of the Agriculture Ministry, highlighting the terrestrial hybrids of the genus Spathoglottis, among them: Bella Lorena, Memory Celia Sánchez Manduley, Sabrina & Abel and Echoes of Festivalia.
Origin
In this work we present the main characteristics of a new orchid cultivar, belonging to the genus Spathoglottis. 'Memoria Aide Alonso', is the result of the crossing carried out in May 2010 between Spathoglottis plicata 'Lorita' and Spathoglottis 'Bella Lorena'. The hybrid seeds were cultivated in vitro and the first plants bloomed in January 2012. After several years of study of the offspring, this genotype is proposed as a new hybrid, which has excellent ornamental potential. It is registered in the database of the Royal Horticultural Society of England, the highest institution responsible for the international registration of hybrid orchids.
