In this issue, the editors have tackled some complicated issues such as Epidendrum compressum Griseb., which is very widespread in South American and has been described multiple times, and sometimes transferred to genera where it does not belong. In addition, there are problems because at least in two cases the “Type” collection was either several specimens of the same species collected in different localities at different dates, and thus the collector's number was used to identify not a particular collection but a particular species.
Clarifying these complications requires searching for all duplicates. We have photographed many of them through visits to the main herbaria in America and Europe and the photographs are housed in the editors' AMO-DATA digital system, together with thousands of live plant photographs downloaded from their contacts on Facebook and other digital platforms.
In this issue, the editors present 52 plates of which 29 are new to science, eleven from Peru, eight from Ecuador, ten from Colombia and one from Brazil (they don't add up to 30 because one is shared by Brazil and Colombia). A number of species are illustrated in colour for the first time, having been published before in Icones Orchidacearum with a botanical illustration only.
