Common Name The Hook Shaped Maxillaria
Flower Size .48" [1.2 cm]
Found in French Guiana, Surinam, Guyana, Venezuela, Colombia, Ecuador Peru and Brazil in wet montane rainforests at altitudes of sealevel to 1300 meters and is a small sized, hot to cool, scadent growing epiphyte with a pendulous stem that has a fusiform-cylindrical, sulcate with age pseudobulb with a solitary semi-terete leaf that blooms at most any time of the year on a short, lateral, subsessile, single flowered inflorescence with subtending scarious sheaths held close into the leaves.
I have mine either mounted on treefern or in a fine mix of sphagnum, fenrock, woodchips, treefern and charcoal. Both plants are in semi-shade and get even year round conditions.
CAUTION I have separated M macleei and its synonyms from this species, please refer to it for more information.
