ORCHIDACE^ 



about nine-nerved. Dorsal sepal about 2 cm. long, 4.6 mm. 

 broad near the base, lance-linear, acuminate, about seven-nerved. 

 Petals about 1.9 cm. long, 3.4 mm. broad above the middle, 

 linear, acute, slightly subfalcate, with only one distinct nerve. 

 Lip about 2.25 cm. long, 1.3 cm. broad a little above the mid- 

 dle, rhombiform, indistinctly three-lobed; lateral lobes shallowly 

 triangular, the anterior margin shallowly and broadly sinuate ; 

 middle lobe about 7.5 mm. long, 6.5 mm. broad across the base, 

 sharply triangular, acuminate; a little below the middle there 

 is a short, sharply three-toothed fascia. Column very short and 

 stout, provided with a fleshy three-toothed wing, extended into 

 a long broad column foot which is deeply saccate near the ex- 

 tremity and which is furnished in the anterior part with a small, 

 fleshy, ligulate, nearly free gland. 



In general appearance the flower of this plant resembles that of 

 Dendrobium crumenatum Sw., but the narrow leaves recall D. 

 teres Lindl., which has a very different lip. Z). lavoiense J. J. Sm. 

 differs from the Kinabalu plant in the position of the much longer 

 bulbous stem thickening and in the character of the lip. In vege- 

 tative appearance D. tridentatum is much like D. linearifolium 

 Teijsm. & Binn., but varies rather widely in flower structure.
