Dendrochilum cagayanense is a near ally of D. Cohhianum. It is a more . 
robust species with narrow sepals and petals and a very different labellum. As 
in D. Cohhianum the lateral lobes of the labellum are inconspicuous and much 
reduced, but are somewhat setaceous. The stelidia of the column are linear- 
triangular and basal. Their tips reach to the base of the obscurely crenulate 
or denticulate terminal wing. . 
Dendrochilum (§ Acoridium) confusum sp. nov. 
SepaJa lateralia 3-nervia, 3 mm longa, 1.75 mm lata. Sepalum in- 
termedmm lateralibus simile. Petala oblanceolata, obtusa, 3-nervia, 3 
mm longa, 1.75 mm lata. Labellum spatlmlatum vel cuneato-obovatum, 
2.75 mm longum, 2 mm latum prope apicem. 
This is the small flowered plant which I described in ''Orchidaceae" II as 
D, bicallosuw- var. minor. More material has come to hand which necessitates 
a revision of my formor views. Aside from the constant difference in the form 
of the labellum and the size of tlie flowers there are other points of dissimilarity 
which I think can not be passed over as merely varietal. Tlicse, however, are 
difficult to describe although apparent when flowers of the two species are com- 
pared side by side. The flowers of D, Ucallosum are more stellate in aspect, 
when flattened out, than those of D. confusum, and their general shape gives 
the impression that the sepals, petals and labellum are longer in proportion to 
the width than the corresponding parts of D. confysilm. The racemes of D. con- 
fusum are much more densely flowered and shorter than those of D. Ucallosum.

Dendrochilum hicallosum has also been found on :\rount Maquiling, where 
it was collected in 1907 by H. M. Gurran d M. L. M^rriii, For. Bur. 7797.
