I purchased this Maxillaria pseudoreichenheimiana ‘Waterfield II’ — the spotted leaf Maxillaria –from Haiku Maui Orchids on my visit to their greenhouses on April 18, 2017. They had several of these Maxillaria, and I had not seen them before (outside of my online links). They were also somewhat overgrown, in that they were all “climbing the tree” and had outgrown their pots vertically.
Maxillaria Pseudoreichenheimiana is a warm to intermediate grower that needs good light. From the web [slightly edited]:
Found in Ecuador and Colombia in wet montane cloud forests at elevations of 230 to 1600 meters as a small sized, hot to warm growing epiphyte… …single flowered inflorescence enveloped by tubular sheaths and holding the flower below the leaves and occurs in the winter.
