12 ORCHIDACEM 



rior to these an erect cucullate appendage. Column 3.5 mm. long, 

 complanate below, subalate on each side above. Anther emargi- 

 nate in front, 2-celled. Fruit an ellipsoidal capsule, 12 mm. long. 



This species was collected on Mt. Mariveles, Province of Ba- 

 taan, Philippine Islands, by Mr. Elmer D. Merrill, on January 1, 

 1904. The plants were found epiphytic on trees growing on 

 exposed ridges. In May, 1904, the species was again collected, 

 presumably near the type locality, by H. N. Whitford. As the 

 flowers appear in succession, only one or two are open at a time. 

 In dried specimens the sepals and petals are strongly reflexed and 

 somewhat pendent. As the inflorescence matures, the lowermost 

 bracts become scarious and eventually fall away. 



GEOGRAPHICAL DISTRIBUTION 

 I have seen specimens from the following locality : 



Philippine Islands : Mt. Mariveles, Prov. Bataan, Luzon, alt. 

 1200 m., January 1, 1904, U. D. Merrill (no. 3736) ; May, 

 1904, H. N. Whitford (no. 317). 



KEY TO THE SECTION DISTICH^, RIDLEY 



The distichous arrangement of the closely set floral bracts gives 

 the species of this section a very marked aspect, dissimilar to that 

 of other members of the genus. The first identification of a mem- 

 ber of the section was du Petit-Thouars's, who defined Malaxis 

 {Liparis) disticha by a plate (Orch. Afr. t. 89). To this species, 

 if those described in the present fascicle are included, eight more 

 have since been added. The foUowing key may be of service in 

 distinguishing them. 



Sepals oblanceolate, obtuse. 



Lip quadrate. 1. C. disticha, Pfitzer. 



Lip 3-lobed. 2. C. araneola (Ridley). 



Sepals lanceolate, acute. 



Lip quadrate, bilobed, lobes divergent. 3. C. divergens (Smith). 



Lip suborbicular — cuneately flabelliforna, often 

 mucronate.
