D. strictiforme (Ames) Pfitzer in Das Pflanzenreich 32 (1907) 116. 
This species was first discovered by Elmer D. Merrill between Suyoe and 
Pauai in Benguet Province. The present specimen was collected in Laguna Proy- 
ince. 
Mount Banajao, Laguna Province, Luzon, at an altitude of 1,400 m, flowers 
white, November 1, 1907, H. M. Curran & M. L. Merritt, For. Bur. 8024. 
D. cinnabarinum Pfitzer in Das Pflanzenreich 32 (1907) 104; Ames Orchida- 
ceae 2: vill; 3: 10; pl. 27, I, B, ob. 
This very interesting species of the Dendrochilum pumilum group has again 
been found. Messrs. Curran, Merritt and Zschokke collected specimens at an 
altitude of 2640 m, January 5, 1909, on Mount Pulog, Province of Benguet, Luzon, 
For. Bur. 16348. Until the rediscovery of the species D. cinnabarinum was only 
known through the specimens gathered in Benguet by A. Loher (no. 461).

C. nutans is a robust species, allied to C. Merrill, 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 Viseaya, Luzon, where H. M. Curran 
collected specimens on December 22, 1908, For. Bur. 10860. The flowers of the 
plant collected by Curran have spurs or nectaries about 10 em long. A com- 
parison between the plants from Luzon and those from Mindoro clearly proves 
that 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
