the stem, free portion lanceolate, acute, about 1 cm wide meas- 
ured perpendicularly. At about the middle of the stem the 
leaves suddenly decrease in size and give place to bract-like 
leaves 5 to 10 mm long, where they are free, which are closely 
appressed, their tips erect and nearly touching the stem. From 
the bases of these bracts, at intervals, the flowers break through. 
Flowers pale-yellowish-white with two lines of dark-carmine 
on the lip. Lateral sepals 3 mm long, triangular-lanceolate, 
subacute. Upper sepal oblong-ovate, obtuse, 3 mm long. Petals 
linear-oblong, obtuse, about 3 mm long, slightly less than 1 mm 
wide. Labellum cuneate-spathulate, 3-lobed in front, the side 
lobes rounded, the middle lobe half-elliptic, obtuse, rounded (in 
dried specimens the margin of each lateral lobe appears to have 
been stained with carmine). In general outline the lip resem- 
bles that of D. Merrillii, and appears to be minutely papillose 
on the disk near the base of the middle lobe. Mentum obtuse, 
2 mm long. Column 2 mm long.

D. marivelense Ames Orchidaceae 2 (1908) 180. 
The above is the bibliographical history of the species which in my 
second volume of “Orchidaceae” I described as a novelty under the name 
D. marivelense. In his monograph of the “Dendrobiinae” Doctor Kranzlin 
concluded that D. parciflorum and D. marivelense should be regarded as 
conspecific. 
In addition to the locality given in Orchidaceae 2: 180, the following 
is of interest: Mindanao, Lake Lanao, Camp Keithley, Mary Strong
