glabrous. Mowers axillary, solitary, few, their pedicels setose, up to 7 
mm in length, the corolla unknown, basal bract minute, less than 1 mm 
long, the apex of the pedicel with two orbicular-ovate bracteoles about 1.5 
mm in diameter. Calyx glabrous except the slightly ciliate margins of the 
lobes, accrescent, the lobes just after anthesis ovate, acuminate, about 2 
mm long; style persistent, 2 mm long.

nerves obsolete except sometimes the very faint subbasal pair. ,

ARDISIA Sw. 
Ardisia biflora sp. nov. § Akosmos. 
Arbuscula glabra usque ad 3 m alta; foliis petiolatis, oblongis vel 
lanceolato-oblongis, integris, chartaceis, valde acuminatis, subtus valde 
glanduloso-punctatis, in sicco nitidis, pallidis; inflorescentiis axillaribus, 
solitariis, tenuibus, bifioris, quam folia multo brevioribus ; sepalis petalis- 
que valde glanduloso-punctatis. 
A shrub 1 to 3 m high, glabrous; branches and branchlets slender, 
terete, gray or brownish. Leaves alternate, oblong to oblong-lanceolate, 
chartaceous, pale and shining when dry, entire, 4 to 8 cm long, 1 to 2.5 
cm wide, the apex strongly acuminate, the base cuneate, the lower surface 
very strongly and densely glandular-punctate; nerves about 10 on each 
side of the midrib, not prominent, slender, anastomosing, the secondary 
ones nearly as prominent; petioles slender, about 5 mm long. Inflores- 
cence axillary, solitary, slender, the peduncle 6 to 10 mm long, bearing 
at its apex two flowers, their pedicels 6 to 8 mm in length. Flowers 
greenish-white, tinged with pink, 5-merous, hermaphrodite. Sepals 
reniform-ovate, less than 1 mm long, united for the lower third, strongly 
glandular-punctate, scarcely overlapping, spreading, rounded, the margins 
minutely ciliate. Petals elliptic-ovate, acute, 3.5 to 4 mm long, prom- 
inently glandular-punctate throughout, the tube about 0.5 mm long. 
Anthers 2 mm long, oblong-ovoid, minutely apiculate, glandular on the 
back, the filaments very short. Ovary ovoid, apparently with few (one?) 
ovules; style 2 mm long. Fruit globose, glandular, about 5 mm in 
diameter. 
Luzon, Province of Zambales, Mount Tapulao, in exposed ridge-forests, altitude 
about 1,400 m, Bur. Sci. 5073 Ramos (type), For. Bur. 8110 Curran & Merritt, 
December, 1907. 
A species apparently belonging in the section Akosmos, strongly characterized 
by its slender, axillary, 2-flowered inflorescences; the apparently 1-ovuled ovary 
is suggestive of Discocalyx, but in all other characters the species is unmistakably 
an Ardisia.
