alternate, imbricating, equitant, compressed, broadly ovate, 
membranaceous scales or bractee: their colour is green, 
beautifully striated with purple at the base ; the upper 
one the largest, having its apex lying over the base of 
the back of the flower. Flower erect, or a little inclined : 
three outer petals erecto-patent, oblong, the two lateral 
ones decurrent at the base, but scarcely forming a spur ; 
yellow buff-colour, the two interior ones erect, linear-lan- 
ceolate, white, punctato-striated with purple on its lower 
half within, its lower inner margin adnate with the column. 
Labellum as long as the inner petals, erect, the sides invo- 
lute, three-lobed, beautifully and longitudinally veined with 
purple, except on the terminal lobe, which is ovate, crisped 
at the margin and spreading. Between the lateral lobes is a 
longitudinal elevated yellow line. Column semicylindrical, 
curved a little forward, deep brownish purple, yellow at 
the base. Stigma quadrangular, placed in the front just 
atthe apex. Anther operculiform, terminal, hemispherical. 
Pollen masses four, two smaller and two larger, elliptical 
or ovate, compressed, yellow, united by a semilunar, large, 
whitish gland, having a purple margin. 
This is a very pretty species of Maxillaria, and very 
distinct from any hitherto described. It was discovered by 
our friend Cuarzes S. Parker, Esq. in Demerara, and by 
him sent to the Liverpool Botanic Garden, where Mr. Suep- 
HERD informs us, it flowers readily (treated in the usual 
manner of the Parasitical Orchidez), and continues a long
