few obtuse bracts. Flowers solitary or paired, 
rather membranaceous when dry, ’’pale green, 
petals pinkish inside, labellum with purplish- 
red median mark inside, very fragrant, wilt 
after about 6 hours” [fide collector], 1.5 cm. 
long, campanulate, borne on vaguely arcuate 
rather robust pedicellate ovaries about 8 mm. 
long. Dorsal sepal linear-lanceolate, acute, 12 
mm. long and 1.5 mm. broad. Lateral sepals 
oblique, basally connate into a large, angular, 
compressed mentum that is triangular-rotund 
and obtuse in shape, about 6 mm. long and 
3 mm. deep; lamina linear-ligulate or ovate- 
ligulate, truncate or obtuse, about 12 mm. 
long and 1 mm. wide. Petals similar in size 
and shape to lateral sepals but more lanceolate 
basally, obtuse apically. Lip small, the tip re- 
curved, about 5 mm, long and 1.5 mm. broad, 
prominently trilobate; lateral lobes erect, 
triangular, forward- slanting, the anterior mar- 
gin strongly dentate; midlobe cuneate-ob- 
long, covered with a dense growth of apicu- 
late papillae, the apex acuminate and almost 
caudate. Column 0.5 mm. long, almost as 
wide, semiquadrate; foot large. 
Mt. Kubersoh, 2,000 ft. alt.: on mossy 
tree trunks, flowers pale green, petals pinkish 
inside, labellum with purplish-red median 
mark inside; blooms very fragrant, wilt after 
about 6 hours. August, 1950, P. A. Adams 
19, TYPE, deposited in the Herbarium of the 
University of California at Berkeley (916873). 
This is a rather handsome species of § Gras- 
tidium, whose closest alliance in the Caroline 
orchid flora is with Dendrobium implkatum 
Fukuyama, D. patenti-filiforme Hosokawa, and 
D. ponapense Schltr. ; it also exhibits some af- 
finity with the Moluccan D. pruinosum Teijsm. 
& Binn. It differs from D. implkatum^ its 
nearest relative, in its more plane lateral 
sepals, the dimensions of the mentum, the 
size and general aspect of the flowers, and the 
more robust vegetative habit. Living material 
of the novelty, which I take pleasure in nam- 
ing for its collector, is in cultivation in the 
Botanical Garden of the University of Cali- 
fornia at Berkeley. 
Dendrobium carolinense Schltr., Engl. 
Bot. Jahrb. 56: 472,. 1920. (§ Grastidium) 
Mt. Kubersoh, 1,200 ft. alt.: on dead tree 
trunk with Bird’s Nest Fern. Flowers pale 
golden yellow with bright orange median 
mark on inside of white labellum. August, 
1950, P. A. Adams 18. A very handsome epi- 
phyte, known now from Kusaie, Truk, and 
Ponape, where it appears to be rather wide- 
spread in its occurrence. 
Dendrobium implicatum Fukuyama, Bot. 
Mag. [Tokyo] 51: 901, fig. 2, 1937. (§ Gras- 
tidium) 
Mt. Tolotom, 1,700 ft. alt.: on trunk of 
hardwood, flower pale pink with darker macu- 
lations, August, 1950, P. A. Adams 3; Mt. 
Tolenkiup, 1,700 ft. alt.: epiphyte, flower pale 
green. August, 1950, P. A. Adams 13. 
The type specimen of Dendrobium impli- 
catum' Fukuyama was collected by T. Hoso- 
kawa in the Palau Islands, with the comment 
”in parinarietis.” Our present material from 
Ponape is fragmentary, but the plants appear 
to be much smaller in all parts than the type 
(e.g., Adams 13 has flowers which measure 
only about 2 cm. long, whereas the lateral 
sepals of Hosokawa 7275 reach a length of 
4-4.5 cm.). Living material is being grown in 
our collections.

(§ Oxyglossum) 
Mt. Tolotom, 2,100 ft. alt.: on mossy trees 
with #1 {Dendrobium violaceo-miniatum Schltr.) 
and #4 {Geissanthera Hosokawae (Fukuyama) 
A. D. Hawkes), also common on the summit 
of Mt. Beirut. August, 1950, P. A. Adams 5; 
Mt. Kubersoh, 2,000 ft. alt.: same sp. as #5, 
on mossy trees. August, 1950, P. A. Adams 
23. 
This is an attractive, very dwarfed epiphyte 
which at first inspection appears to be a 
species of Bulbophyllum Thou. The section 
Oxyglossum is predominantly New Guinean in
