20, 4 Merrill: Noteworthy Philippine Plants, XVII 467 
A species somewhat resembling Lasianthus morus Elm., but 
differing distinctly in its indumentum and in its calyx lobes. 
It differs from Lasianthus acuminatissimus Merr. in its indumen- 
tum, wider leaves, very different stipules, and conspicuous, 
persistent bracts and bracteoles. 
LASIANTHUS ACUMINATISSIMUS sp. nov. 
Frutex circiter 1 m altus, ramis ramulisque minute et obscure 
adpresse hirsutis; foliis chartaceis, anguste lanceolatis, 9 ad 
20 cm longis, 1.5 ad 3 cm latis, sursum sensim angustatis, ten- 
uiter caudato-acuminatis, basi acutis, supra olivaceis, glabris, 
subtus ad costa et nervis reticulisque breviter pubescentibus, 
nervis utrinque circiter 7, curvato-adscendentibus, perspicuis; 
floribus paucis, fasciculatis, sessilibus, 5-meris, ebracteolatis, 
calycis breviter 5-dentatis, corollae tubo cylindrico, 5 mm longo, 
intus villoso, lobis oblongis, 3 mm longis, intus villosis. 
An erect shrub about 1 m high, the branches and branchlets 
terete, brownish or olivaceous when dry, minutely and obscurely 
appressed-hirsute with short hairs, the ultimate branchlets 1.5 
to 2mm in diameter. Leaves chartaceous, narrowly lanceolate, 
9 to 20 cm long, 1.5 to 8 cm wide, gradually narrowed upward 
to the slenderly caudate-acuminate apex, the base acute, the 
upper surface olivaceous, glabrous, somewhat shining, the lower 
surface shortly pubescent on the midrib, nerves, and reticula- 
tions, the indumentum yellowish green; lateral nerves about 7 
on each side of the midrib, curved-ascending, distinct on both 
surfaces as are the reticulations; petioles more or less pubescent, 
5 to 7 mm long; stipules linear to linear-lanceolate, pubescent, 
nearly as long as the petioles, deciduous. Flowers few, white, in 
axillary sessile fascicles, 5-merous. Calyx 3 mm long, slightly 
pubescent, the teeth triangular, acute, 0.5 mm long, their margins 
slightly ciliate. Corolla tube cylindric, somewhat pubescent 
externally, about 5 mm long, glabrous inside in the lower 
half, villous in the upper half, the lobes oblong, 3 mm long, villous 
inside. Anthers oblong, 2.2 mm long. Disk cushion-shaped, 
1 mm long, glabrous. Style 6 mm in length. 
Luzon, Bontoc Subprovince, Mount Caua, Bur. Set. 38058 
Ramos & Edafio, March, 1920. In the mossy forest, altitude 
about 1,800 meters. 
A species belonging in the general group with Fasionthus 
morus Elm., well characterized, however, by its elongated, nar- 
rowly lanceolate, caudate-acuminate leaves.
