2. M. flavescens (Lindl. Sertum, sub t. 48.  Cyrtochilum 
flavescens, Lindl. in Bot. Reg. t. 1627); pseudobulbis 
angustissimis ancipitibus levibus, foliis lineari-ensiformi- 
bus binis scapo æqualibus, scapo compresso arctissimè 
vaginato, racemo multifloro, bracteis glumaceis flaves- 
centibus carinatis pedunculi longitudine, sepalis petalis- 
que linearibus acuminatis, labello ovato-lanceolato 
repando crispo basi pubescente inappendiculato. Said 
to inhabit Mexico, but most probably Brazil. 
Flowers bright yellow with no spots, but a few crimson 
specks and streaks on the lip. Wings of the column 
crimson. 
3. M. stellata (Lindl. Sertum, sub t. 48. Cyrtochilum stel- 
latum, Lindl. Sertum, t. 7); pseudobulbis diphyllis 
ovalibus ancipitibus, foliis ligulatis obtusis scapo multö 
brevioribus, scapo tereti erecto vaginato, racemo disticho 
multifloro, bracteis carinatis convolutis acuminatis 
glumaceis ovario longioribus, sepalis petalisque lineari- 
obovatis acutis stellatis, labello oblongo undulato acuto 
basi canaliculato striato, alis columnæ acinaciformibus 
integerrimis... Brazil. Flowers pale yellow with 
no spots, lip white with yellow streaks. Wings of the 
column yellow streaked with crimson. Bracts rose- 
coloured. This has much larger flowers than the last 
species, its sepals and petals are not taper-pointed, its 
pseudo-bulbs are much broader, its stature four times as 
great, and the colours of the parts different, as will be 
seen upon comparing the above descriptions. 
4. M. candida (Lindl. in Bot. Reg. 1838. misc. 29. Sertum 
Orchidaceum, t. 21.) ; pseudobulbis ovatis apice angus- 
tatis diphyllis, foliis angustis racemo brevioribus, 
bracteis brevibus ovatis membranaceis concavis squamæ- 
formibus, sepalis petalisque oblongis æqualibus, labello 
subrotundo crispo circa columnam convoluto basi 5- 
lamellato, columná pubescente basi biauri, clinandrio 
crispo membranaceo-marginato utrinque in alam decur- 
rente.—— Brazil.—— Flowers in long erect racemes, 
very large; sepals and petals spotted with brown ; lip 
white. There is a large flowered variety in cultivation. 
5. M. cuneata. 
6. M. Russelliana (Lindl. in Sertum, sub t. 48. Oncidium 
Russellianum, Lindl. in Bot. Reg. t. 1830); pseudo- 
bulbis ovatis costatis diphyllis, foliis ligulato-lanceolatis 
patentibus, racemo paucifloro, bracteis acuminatis ovario 
3-plo brevioribus, sepalis petalisque conformibus ovato- 
oblongis subundulatis, labello postico oblongo-cuneato 
retuso apiculato subsinuato, lamellis disci pluribus trun- 
catis, columnæ bidentatæ alis magnis falcatis, stigmatis 
margine incrassato pubescente colorato... Brazil.
