CESTICHIS Pfitzer. 

 C. nutans sp. nov. 



Pseudobulbi 3 cm longi, pyriformes. Folia oblonga, acuta; 3 dm longa, 

 2-3 cm lata. Sepala 7 mm longa, 3 mm lata. Petala linearia, 7 mm 

 longa, 0.5 mm lata. Labellum cuncato-flabellatum, 8 mm longum, prope 

 apicem 8 mm latum, callo ad basim. Columna arcuata, 6 mm longa. 



C. nutans is a robust species, allied to C. Mcrritlii. with oblong acute 

 leaves which are considerably longer than the winged scape. The raceme 

 is slender and nutant. The flowers according to the collector's notes are 

 brick-red. The labellum is cuneate-flabellate in outline, 2 mm wide at 

 the base, and near the point of union with the column very fleshy, and 

 somewhat channelled.

This species which was originally collected on Mount Halcon by E. D. Merrill, 

 has been found at Imogen. Province Nueva Yiscaya. Luzon, where II. M. Curran 

 collected specimens on December 22, 1908, Fur. Bur. 10860. The flowers of the 

 plant collected by Curran nave spurs or nectaries about 10 cm long. A com- 

 parison between the plants from Luzon and those from Mindoro (dearly proves 

 thai the spur of the type was not fully developed on the date of collection. 

 This statement is sufficient to account for the discrepancy between the measure- 

 ments given above and those published in the original description. It is a 

 well established fact that the spurs in orchids increase in length as the flowers
