ORCHID ACE JE 115 



Abundant, alt. 3700 ft., Mt. Malindang, Prov. Misamis, Minda- 

 nao, May, 1906, Maj. JE. A. Mearns and W. J. Hutchinson (no. 

 4597). 



In habit D. 7nalindangense resembles D. glumaceum. The 

 labellum is without lateral lobes, and is denticulate on the margin 

 from the base to above the middle. To judge from the descrip- 

 tion of D. spathaceum Reichb. f., D. malindangense belongs very 

 close to it.

 dium Copelandii Ames Proc. Biol. Soc. Wash. 19 : 153 (1906). 



Pseudobidbs oblong, narrowed above, 33^3 mm. long. Leaves 

 lanceolate, acuminate, obtuse or subacute, many-nerved, 9-17 cm. 

 long, 18-25 mm. wide. Petiole 4-5 cm. long, grooved. Peduncle 

 8-9 cm. long, shorter than the leaf. Inflorescence an elongated, 

 slender, many-flowered raceme, 5 mm. through, about 10 cm. long. 

 Bracts 3 mm. long, obtuse, longer than the ovary. Flowers about 

 1 mm. apart. Lateral sepals ovate-lanceolate, acute, 3-nerved, 2.5 

 mm. long. Upper sepal similar to the laterals. Petals oblong, 

 acute, 2 mm. long. Labellum entire, broadly lanceolate, obtuse or 

 subacute, ecallose. Column stout, 1.5 mm. long, lateral wings 

 from near the summit, end wing 3-lobed. 



I have not seen D. bistortum (Wendl. & Kranzl.) J. J. Smith, 

 but D. Copelandii must be closely allied to it according to the 

 figure in Xenia Orchidacea, vol. 3, t. 299, fig. 1, 1-5, although 

 the inflorescence is very different. 



A single unnumbered specimen in the herbarium of the Bureau 

 of Science, Manila, from Distr. Zamboanga, Mindanao, 1905,
