During his trip, he was successful not only in collecting M. veitchiana but several other species of the genus, including the graceful violet-blue M. ionocharis (which he found in the Andean valley of Sandia, in the province of Carabaya, Peru, at 9000 feet elevation) and the golden-yellow M. davisii (the Incas' Qoriwaqanki or "golden waqanki"), which Davis discovered in the vicinity of Cusco, Peru.
