the leaves for nearly the entire length of the leafy portion of 
the stem. Racemes about 5-flowered. Bracts of the raceme 
about 5 mm. long, linear-lanceolate, acute, spreading. Ped¬ 
icels very short, almost obsolete, with the verruculose un¬ 
fertilized ovary 3 mm. long, the fertilized ovary at ma¬ 
turity 8 mm. long. Lateral sepals 3 mm. long, triangular, 
acute, forming a blunt mentum which is 3.5 mm. long. 
Mentum 2.5 mm. in greatest diameter, laterally flattened or 
compressed. Dorsal sepal 3 mm. long, narrowly elliptical, 
strongly concave, obtuse, near the base on the outer surface 
somewhat verruculose. Petals 3 mm. long, 1.5 mm. wide, 
elliptic-oblong, obtuse, 3-nerved. Labellum with the lower 
half adnate to the wide foot of the column forming a blunt 
sac which is wholly concealed by the sepalous mentum, 
upper half expanded into a suborbicular or orbicular obtuse 
fleshy lamina which is 2 mm. long; the sac itself is almost 
3 mm. long with a heavily thickened keel on the inner side of 
the anterior wall. Disc near the opening to the sac provided 
with long, weak, glandular hairs. Column from the base of 
the upper sepal to the tip of the deep excised rostellum 2 mm. 
long, prolonged at base into a conspicuous elongated foot. 
In habit not unlike Appendicula Fenixii Ames, but very 
different from it in the structure of the labellum.
