close strap-shaped leaves, 5 inches in length by | an inch across, 

 dark green, with the apices recurved. From the axils spring about 

 six slender peduncles on each plant, about 2 inches long, bearing 

 a few loose brown sheaths. The ovary and pedicel are about 

 2| inches in length, erect or a little spreading. The posticous 

 sepal is erect. The laterals, together with the petals, are thrown 

 forwards at right angles to the erect column. At the base they 

 are adnate to the column, and the lateral lobes of the lip and 

 their edges at this spot are crisped and wrinkled. The base of 

 the lip is thickened and curved downwards, and the side lobes 

 are erect, so as to form a guiding passage to the entrance of the 

 spur. The middle lobe of the lip is spathulate in shape and 

 acute ; it is bent up, making an angle with the base so as to be 

 parallel to the petals. The whole lip is somewhat shorter than 

 the sepals, which are three quarters of an inch in length. The 

 spur is 4 inches long, the first inch of which is almost parallel 

 with the ovary ; it is then bent up abruptly, almost at right angles, 

 taking a sigmoid curve. The column is short, but proportionally 

 longer than in A. sesquipedale. The lobes of the rostellum are 

 rather large, and overhang the entrance to the spur. Thepollinia 

 are oblong, grooved on the back so as to be almost bilobed, the 

 hind lobe being the smaller one. The caudicles are very short, 

 the glands separate, ovate, acute, and flat.

The affinity of this plant is with A. recurvvm, Thouars. It has 

 a stout stiff stem, about 1 foot in height, covered with the bases 

 of the old leaves, and terminated by a few short, blunt, unequally 

 bilobed leaves, 1 inch long by \ in breadth. The flowers occur 

 singly, each supported on a slender peduncle, covered with 3 

 or 4 shcathing-leaves. They are rather bigger than those of
