Petals greenish white, pink at bases. Spur of 
chin deep red. August, 1950, P. A. Adams 16;

Nest Fern. August, 1950, P. A. Adams 22. 
Bulbophyllum micronesiacum Schltr. is also 
known from Yap and Rota, and from Babel- 
thuap in the Palaus. It is a very distinctive and 
handsome large-flowered species allied to 
B. guamense Ames from the Marianas. Living 
material is in cultivation at the Botanical 
Garden of the University of California at 
Berkeley. 
Bulbophyllum urceolatum A. D. Hawkes, 
sp. nov. ( Fig. 1 ) 
Herba epiphytica nana repens. Rhizoma 
repens, cylindricum. Pseudobulbi ascendentes 
arcuati semi-erective, ovoidei usque ad cylin- 
drico-ovoidei, leviter angulati, diphylli. Folia 
2, id interiorum insigniter parvius ac minus 
evolutum, erecta arcuatave, coriacea, ovato- 
lanceolata usque ad oblongo-lanceolata, plus 
minusve carinate apiculata vel oblique bilo- 
bata, basi angustiora conduplicataque. In- 
Eorescentia verisimiliter terminalis, erecto- 
arcuata, uniflora; rachis leviter angularis. 
Flores solitarii, erecto-arcuati, urceolati, cori- 
acei. Sepala basi coherentia apice ecurvata, 
triangulari-lanceolata triangulari-ovatave, 
acuta, marginibus patrium liberarum leviter 
introrsis; lateralia basi mentum rotundo- 
truncatum formantia, prominente carinata. 
Petala sepalis aequilonga, lineari-lanceolata, 
infra medium abrupte expansa, acuta, apice 
ecurvata, basi truncata. Labellum semi- 
transparens, textura tenuissima, immotum, 
expansum obovatum, basi unguiculatum, 
subacutum, ecallosum, prope basin saccum 
truncatum formans, margine laterali leviter 
incurva, disco lineas irregulares longitudinales 
aliquanto impressas ferente. 
Dwarf creeping epiphytic herb. Rhizome 
repent, 2-3 mm. in diameter, more or less 
covered with somewhat leathery, brown 
sheaths, giving off pseudobulbs at intervals, 
mostly cylindrical. Roots filiform, flexuose.

brown or reddish-maroon, distinctly villous 
when young, later glabrous. Pseudobulbs 
produced at intervals, 2-12 mm. apart, 
ascending, somewhat arcuate or semi-erect, 
ovoid to cylindrical-ovoid, often vaguely 
angular (especially when young), wrinkled 
when old, 12-15 mm. long, 6-8 mm. in diam- 
eter near base, narrowing above, diphyllous; 
basal sheaths usually geminate, caducous, 
scarious, triangular - lanceolate, acuminate, 
about 1 cm. long and about 8 mm. broad 
basally. Leaves 2 (one often caducous), the 
inner one much smaller and less developed, 
erect or arcuate, leathery, light green, ovate- 
lanceolate to oblong-lanceolate, more or less 
carinately apiculate to obliquely bilobate, 
narrowed and conduplicate basally, 4-7.5 cm. 
long, 8.5-16 mm. broad at widest point; 
secondary leaf less coriaceous in texture, 
carinately apiculate, rather conduplicate, ob- 
long-lanceolate to ovate-lanceolate, about 
2.5-3 cm. long, about 5-7.5 mm. broad. In- 
florescence apparently terminal, erect-arcuate, 
1 -flowered, to about 4 cm. long; rachis 
vaguely angular, about 1 mm. in diameter, 
tinged with vermilion above the bract, green 
below; bract solitary, clasping basally, sub- 
membranaceous, triangular-lanceolate, long- 
acute, about 2 mm. long. Flower solitary, 
erect-arcuate, urceolate, coriaceous, the sepals
