ORCHIDACE.E 



rigid, about equaling the pedicellate ovary. Flowers small, about 

 2 mm. apart. Lateral sepals about 3.5 mm. long, 2 mm. wide, 

 strongly reflexed at the tip, falcate, ovate-lanceolate, acute, three- 

 nerved. Dorsal sepal lanceolate, acute, 4 mm. long. Petals lanceo- 

 late, acute, about 3.5 mm. long, obscurely three-nerved, margin 

 obscurely denticulate. Labellum ±2 mm. long, rotundate, apicu- 

 late, margin shortly fringed, the fringe irregular, bicallose, middle 

 nerve somewhat prominent. Calli conspicuous, semi-orbicular, 

 erect, fleshy, about half as long as the lip, one on each lateral 

 nerve, confluent at base by a transverse ridge. Gynostemium 

 short, fleshy. Lateral wings rotund, basal, shorter than the col- 

 umn. Terminal wing rounded, entire. 



The lateral wings of the column are unusual and indicate 

 affinity with D. alatum. An unnumbered specimen secured by 

 Clemens, referable through its flowers to D.Jimbriatum, is habit- 

 ally similar to D. alatum. The pseudobulbs are elongated and the 

 leaf exceeds 1 dm. in length. Unfortunately the material is lim- 

 ited and insufficient to establish the range of probable variation.

 Soc. 42 (1914) 147. 



From a study of drawings of this species preserved in my her- 

 barium, it would seem that JJ. Gribbsiae is a very near ally of 

 Z>. kinabaluense Rolfe. There is reason to believe that the exami- 

 nation of more ample material will indicate that the characters 

 relied on for the separation of these species will break down.
