neled-concave, narrowed upward; inner petals 3, glabrous or very 
slightly pubescent toward their apices, coriaceous, oblong-ovate, 
slightly acuminate, about 9 mm long and 4 to 4.5 mm wide, 
keeled. Anthers many, 2.2 to 2.5 mm long, the cells concealed by 
the overlapping connectives. Carpels numerous, densely fer- 
ruginous-hirsute, including the style and stigma about 2.5 mm 
long, the style glabrous, slender, thickened upward.

in forests back of the beach. Possibly referable here is For. Bur. 17901 
Barros, from Cagayan Province, Luzon, November, 1912, but the specimen 
is old, poorly prepared, and in fruit only. 
The alliance of this species is with Oxymitra latifolia Hook. f. & Th. of 
the Malay Peninsula, but with more numerous lateral nerves, larger flowers, 
and longer pedicels. From Oxymitra longiflora Merr. it differs notably in 
its shorter flowers.

GONIOTHALAMUS COPELANDII sp. nov. 
Arbor glabra vel subglabra; foliis oblongis, chartaceis, usque 
ad 20 cm longis, basi acutis apice brevissime abrupte acuminatis, 
nervis utrinque circiter 18, subtus prominentibus, anastomosan- 
tibus; floribus in ramis defoliatis, solitariis vel fasciculatis, pe- 
dicellatis, circiter 5 cm longis, petalis interioribus carpellisque 
pubescentibus, cetero glabris; stigmatibus anguste hypocrateri- 
formibus, truncatis, fissis. 
A tree about 15 m high, quite glabrous except the terminal 
buds, the interior petals, and the carpels. Branches terete, dark- 
colored when dry, wrinkled. Leaves oblong, chartaceous, rather 
pale when dry, slightly shining and of about the same color on 
both surfaces, the base acute, the apex abruptly and very shortly 
acuminate; lateral nerves about 18 on each side of the midrib, 
rather slender but very prominent on the lower surface, dis- 
tinctly anastomosing, mostly impressed on the upper surface, the 
reticulations slender, lax, not prominent; petioles 1 to 1.5 cm 
long. Flowers greenish, tinged with lavender, on the branches 
below the leaves, solitary, in pairs, or in fascicles, their pedicels 
about 2 cm long, subtended by small bracts. Sepals thickly 
coriaceous, ovate, about 14 mm long, 9 mm wide, rounded, rather 
distinctly nerved, glabrous. Outer three petals very thickly 
coriaceous, almost fleshy when fresh, glabrous, oblong to oblong- 
ovate, the apex rounded, margins thickened and somewhat in- 
curved, 4 to 5 cm long, 2 to 2.5 cm wide, the base somewhat 
contracted to a width of about 7 mm and there slightly concave; 
inner three petals connivent into a cone by their very thick
