itonia Phalaenopsis was originally introduced by M. Linven, he having 
received it from one of his collectors, M. Scum, in 1850. It was 
described in 1854 in Bonplandia, and afterwards figured in Pescatorea, 
under the name of Odontoglossum Phalaenopsis, which was given by REIcHENBACH. 
Several species formerly placed in the genus Odontoglossum by this author have 
since been transferred to Miltonia; notably Odontoglossum vexillarium, O. Roezlii, 
and O. Warscewiczii (Miltonia Endresii Nicuouson), species closely allied to the 
one we are now occupied with. 
M. Phalaenopsis was discovered by Scuum in New Granada, “ in the damp 
and shady forests of Aspasica, at an elevation of about 5000 feet above the sea- 
level. > M. Linven, in his description in Pescatorea, states that it is a terrestrial 
species, covering the rocks and growing readily among mosses in these damp 
and shady localities. A single example sometimes forms a clump of over a yard 
across, and is literally covered with flowers, which begin to expand about April, 
and are successively produced until July. ” 
M. Phalaenopsis has narrow and remarkably grass-like leaves, ovoid pseudo- 
bulbs, somewhat compressed, and of a very pale green. Its flowers, though 
without the shape and quality of certain forms of M. vevxillaria, are extremely 
graceful; the sepals and petals are spreading, flat, and pure white, and the lip
