Today I was working in the greenhouse and noticed that four of the larger spotted Restrepia species were blooming in the same tray and I thought "what a marvelous teaching moment".
If you own any of the spotted Restrepia or are blooming them for the first time it is difficult to tell some of them apart. Here are 4 that are similar until you put them next to each other.
The first picture is labeled and shows all four of them side by side, well, as close as I could get them.
Here is a close up of Restrepia guttulata
Next this is Restrepia sanguinea
This is a close up of Restrepia elegans
Lastly Restrepia dodsonii. This one and guttulata are very often mistaken for one another. There is a distinct pair of lighter colored lines running parallel off center in R. dodsonii as seen in this shot
I apologize for the heavy photo content. I hope these photos are helpful if you are trying to identify your large spotted Restrepia.
