The upper sepal is about the same size as the other, but is 

 more concave and pointed. Petals oblique, ovate-acuminate, 

 of the same colour, but rather shorter than the sepals, and 

 about three-fourths of an inch wide, having their edges slightly 

 undulated and the point recurved. Labellum three-lobed, out- 

 wardly of purplish-red colour, but inwardly more pale and deli- 

 cate towards the base, where it tapers and forms a sort of pouch. 

 The two lateral lobes are erect and of a pale brownish-red, 

 marked with dark coloured veins. The middle lobe is roundish 

 oblong, recurved and undulated at the margin. Outside it is 

 smooth, but the inner surface is thickly covered with pale soft 

 hairs. In the centre of the lip is an elevated process, similar 

 to those in the flowers of M. aromatica, cruenta, tetragona, 

 and other allied species. Column about half the length of ttie 

 labellum, slightly curved, of a pale yellowish colour above 

 where it was rounded, and slightly tinged with red below, 

 where it is hollowed out so as to appear two-edged. Anther- 

 case large and fleshy, one-celled, containing two collateral pol- 

 len-masses, each of which easily splits into two roundish ovate, 

 slightly pointed waxy bodies of a dull yellow." — W.B. Booth. 



For this memorandum, a drawing, and specimens of the 

 highly curious plant, I am obliged to Mr. Booth, Sir Charles 

 Lemon's intelligent gardener. s The species is much the finest 

 yet known, its flowers being as large as those of Maxillaria 

 Harrisonise. 



The Maxillaria tetragona above referred to, as resembling 

 this in habit, belongs to the genus Ly caste, in my recent enu- 

 meration of whose species, it was unsettled. I therefore avail 

 myself of the present opportunity of adding its amended 

 character.

 Mag. t. 3146 ) ; pseudobulbia ovatis tetragonis, foliis oblongo-lanceolatis 

 plicatis basi in petiolum angustatis solitariis, scapis 1-4-noris pseudo- 

 bulbia brevioribus, sepalis petalisque oblongo-ovatis obtusiusculis patulis 

 subaequalibus, labello carnoso ventricoso trilobo erecto : lobis lateralibus 

 parvis acutis intermedio ovato extus convexo, disci appendice carnoso 



tabulari incumbente. Brazil. Very sweet-scented. Flowers
