Wow .. this is one orchid I can find very little info on .. I did find, however that Woodstream Orchids has a Maxillaria horichii - "(Panama) This species is quite similar to neglecta and pseudoneglecta, having small pseudobulbs separated by several inches, along a narrow rhizome, giving a cascade effect. Dense clusters of bright orange flowers appear several times a year. Grow intermediate, with moderate light, evenly moist." from
