M. luteo-alba.—A very robust and free-flowering species, 
easily cultivated. Pseudo-bulbs 23in. long, ovate, com- 
pressed, one-leaved. Leaves broad, blunt-pointed, dark 
green, Ift. long, the base narrowed and stalk-like. The 
scapes spring from the base of the pseudo-bulbs, and are 
6in. long, clothed with sheathing bracts, one-flowered; 
each flower is 6in. across; the sepals are jin. long, 
brown at the back, nearly }in. wide, tawny yellow except 
at the base, which is creamy white, the upper one erect, 
the lower ones drooping and suggestive of the lop-ears 
of a rabbit; the petals are erect, pointed forward, half 
as long as the sepals, white at the base, then brown, yellow 
above; the lip is three-lobed, the side lobes erect, yellow, 
with purple stripes, the middle lobe recurved, hairy, yellow, 
with white margins. This plant is worth a place where 
large specimens are wanted, as it soon fills a large pan, 
and is ornamental even when not in flower, whilst when 
in blossom it has a singular and attractive appearance. 
It was introduced from New Granada in 1846. Syn.

M. nigrescens.—This is a useful, free-flowering species, 
deserving to be grown on account of the colour of its 
flowers, which is a deep vinous red throughout, shaded 
with dull purple; the blossoms are about 2in. across, 
and they are borne on erect scapes, 4in. long. The 
pseudo-bulbs are oval, compressed, blackish. The leaves 
are strap-shaped, acute at the tips, 1ft. long, rin. broad. 
The plant thrives under quite cool treatment. It is a 
native of New Granada, and was introduced in 1849.
