COLLECTED IN DUTCH NEW GUINEA. 177 
Camp VI 2, 3900 ft. 
A species very distinct by its large flower, with elliptic petals narrowed at the base 
and broader than the sepals, and the very small lip. 
DIPLOCAULOBIUM LINEARIFOLIUM, Ridl., sp. nov. 
Pseudobulbi in rhizomate 3 mm. crasso congesti, lageniformes, 5 mm. longi, 4 mm. 
crassi, superne filiformes, 5-6 cm. alti, vaginis ad basin papyraceis tenuibus lanceo- 
latis acuminatis 3 cm. longis. Folium lineare, acuminatum, coriaceum, 10 cm. 
longum, 2 mm. latum. Bractea linearis, ochrea, polita, 1 em. longa, 1 mm. lata. 
Pedicellus filiformis, tenuis, 2-3:5 cm. longus. Flos solitarius, raro 2. Sepalum 
posticum basi lineare, filiforme, 2:5 cm. longum, lateralia e basi triangulari fili- 
formia; mentum curvum, obtusum, 5 mm. longum, ad basin 4 mm. latum. Petala 
e basi lineari filiformia, 2 cm. longa. Labellum panduratum, 1 em. longum, basi 
dilatatum, in medio angustatum, apice ovato obtuso 3 mm. lato, margine undulato, 
carinis 2 sinuatis e basi ad medium lobi terminalis excurrentibus approximatis 
parallelis, disco inter eas pulverulento. Columna brevis, margine clinandrii denti- 
eulato. Anthera campanulata, pustulata, filamento 1 mm. longo. 
Camps III, 2500 ft., and VI d, 3900 ft. 
Perhaps nearest to D. gracilentum, Schlechter, but with a very different lip, more 
resembling that of D. crenulatum, J. J. Sm., from the latter distinguished by much 
larger petals and sepals. The apices of the sepals and petals and the tip of the mentum 
are pink. 
DIPLOCAULOBIUM HUMILE, Ridl., sp. nov. 
Pseudobulbi congesti, basi cylindrico-conici, 1 em. longi, rugosi, superne graciles, 
2 em. longi. Folium lineare, apice acute bifidum, 5 em. longum, 2 mm. latum. 
Bractea lanceolata, acuta, 6 mm. longa.  Pedicellus filiformis, 2 cm. longus. 
Sepala e basi triangulari caudiformia, 3 em. longa; mentum breve, obtusum, 3 mm. 
longum. Petala e basi lineari filiformia. Labellum 5 mm. longum, 15 mm. latum, 
oblongum, obtusum, apice rotundato integro, nervis 3 flavis undulatis in disco 
apicem versus in unum conjunctis. Columna parva; stelidia erecta, dentiformia. 
Anthera conica, filamento lineari longiusculo. 
Camp VI a, 3100 ft. 
The flowers appear to have been white, the lip with a purple puteh on each side, and 
yellow keels, the column dark brown and the anther white. 
Allied to D. gracilentum, Schlechter, but with filiform petals and sepals, and three 
nerves on the lip. 
DIPLOCAULOBIUM FILIFORME, J. J. Sm. Ic. Bogor. ii. 73, t. 113 D. 
Camp I, 700 ft., to Camp III, 2500 ft., and Camp VII, 3900 ft. 
Distrib. 
I have little doubt that this is the species intended by Smith, and based on a plant of 
unknown origin in Hort. Buitenzorg; but if so, the figure above quoted is a very poor 
one.
