erectum. Scapus gracilis, foliis longior, flexuosus, circiter 1.5 
dm longus. Bracteae inflorescentiae distichae, confertae, condu- 
plicatae, circiter 5 mm longae, valde acutae. Racemus usque ad 
3.5 cm longus, complanatus, circiter 5 mm in diametro. Flores 
flavidi, fragiles, succedanei, eodem tempore singuli vel perpauci 
aperti. Sepala lateralia oblongi-lanceolata, acuta, 5 mm longa, 
1.25 mm lata. Sepalum dorsale simile. Petala filiformia, circiter 
5 mm longa. Labellum panduratum, circiter 5 mm longum,

Mindanao, District of Zamboanga, Merrill 818i, November 5, 1911. 
Cestichis fragilis resembles most closely in general habit C. gracilis and 
C. disticha. From the former it is easily distinguishable by the broader 
leaves and from the latter by the construction of the labellum.

Luzon, Province of Rizal, Wawa, D. LeRoy Topping s. n., October, 1908. 
The form of the labellum is not dissimilar from that of Oberonia insec- 
tifera Hook. f. Among Philippine species it is very distinct.
