ORCHIDACEM 101 



blunt ends turned toward the column. In its natural state the sides 

 of the lip are nearly erect. — The above description, based partly 

 on the type and partly on additional material, is given to supple- 

 ment Mr. Rolfe's description published in fascicle 1 of this work. 

 D. Whitfordil is of special interest on account of its lip, which 

 lacks the conspicuous lateral lobes so characteristic of D. tenellum 

 and its allies.

 ocellatum Ames Proc. Biol. Soc. Wash. 19: 151 (1906). 



A diminutive, coriaceous-leaved species, with ocellate sepals and 

 petals. Pseudobulbs 1 cm. long, about 5 mm. thick, ovate-oblong 

 or pyriform, strongly rugose. Leaves shortly petiolate, oblong, 

 3.5^£.5 cm. long, 5-6 mm. wide, obtuse. Petioles 5 mm. long. 

 Peduncle below the inflorescence about as long as the leaf, few- 

 flowered. Bracts 3 mm. long, erose-margined, longer than the ova- 

 ries. Later al sepcds ovate, obtuse, 2 mm. long, 1 mm. wide. Upper 

 sepal elliptic-oblong, obtuse, 2 mm. long, 3-nerved, the nerves 

 branched. Petcds ovate, about 2 mm. long, 1 mm. wide, like the 

 sepals provided with diaphanous areolae or ocelli scattered among 

 the semiopaque tissues. Labellum fleshy, about 1 mm. long, 1.5 

 mm. wide, pentangular, acute, the apical angle forming a triangu- 

 lar tooth ; near the centre on the median line a minute papilla is 

 situated between two truncate tubercles. Column short and stout. 



D. ocellatum is readily distinguished from all other Philippine 

 species of the section Acoridium by the scattered ocelli on the 

 sepals and petals.
