Thouars. The dorsal sepal is much smaller than the laterals ; it 

 is erect, ovate, and blunt, \ of an inch long ; the petals are wider 

 than the sepals, \ an inch long, 5-veined. The lip is almost 

 ohcuneate, \ an inch long and the same across in the broadest 

 part, 7-veined. The spur is 1 inch long, cylindrical, and hang- 

 ing vertically downwards for the greater part of its length, and 

 then abruptly bent at an obtuse angle, at which point it is much 

 dilated. The column, as in its allies, is rather longer than usual 

 (1 line), glabrous, semiterete, and slightly curved ; the stigma is 

 oval ; the anther is ovate acute. The pollinia are fixed to a single 

 gland with an obcuneate flat caudicle. The rostellum resembles 

 that of A. modestum, to which this plant is allied. The capsule 

 is about 1 inch long and 2 lines thick, obscurely 3-angled, with 

 low ribs.

A stout plant with cuneate-lanceolate leaves, 5 inches in length 

 and 1 in diameter. The raceme is about a foot in length, the 

 rhachis and bracts brown, and bears from G to 9 white flowers 

 about as big as those of A. gladiifoliuin. The sepals are lanceo- 

 late, I an inch long and 2| lines across ; the petals a little broader 

 and shorter. The lip is similar in shape to the petals, but 

 broader and more acute and fleshy, h an inch long and \ across ; 

 it clasps the column at the base, and below the latter is a slight 

 depression leading to the spur, over which hangs the rostellum 

 and caudicle of the pollinia. The spur is 4 inches in length, 

 filiform, broadest at the base, gradually tapering to a point. The 

 column is straight, yellow, rather thick and sparingly hispid ; it 

 is about 2 lines long. The anther is conical, with rather a long 

 apiculus ; inside it has two small flaps or pockets which make it 

 nearly bilocular. The pollinia are rather large, | a line in length, 

 oblong, with a small groove in the back. They are attached to a 

 long (1| mm.) caudicle, which lies in a groove of the rostellum, 

 and bears a broad oblong gland (1 mm. long), which shows some 

 signs of its double origin in having a notch at the point. The 

 rostellum is subterete and horn-shaped, curved up at the end, and 

 overhanging the stigma and mouth of the spur. There is a 

 groove along the upper surface, in which lies the caudicle, aud the
