& Ramos, March, 1911, on rocks along the river, altitude 75 to 100 meters, 
the flowers white and greenish. 
A most characteristic species, recognizable by its small size and its 
lanceolate, sharply acuminate leaves. The narrow leaves have doubtless 
been developed to meet the exigencies of its habitat, for the plant undoubt- 
edly grows in situations subject to overflow during heavy rains. It has 
almost exactly the habit and appearance of Atalantia linearis (Blanco) 
Merr., and Eugenia mimica Merr., which grow in similar habitats, and in 
fact in making the preliminary identifications of the Guinatacutan collec- 
tion, the specimens were referred to Atalantia linearis. 
Stenophylly, due to habitat, is not as highly developed in the Philippines 
as in the neighboring Island of Borneo, and aside from the widely distrib- 
uted Homonia riparia Lour., we have the endemic species Atalwntia linearis 
Merr., Eugenia mimica Merr., Buxus rivularis Merr., and Ficus rivularis 
Merr., and doubtless others remain to be noted. The rather numerous 
Bornean forms have been considered by Beccari. 3 
BUXUS PACHYPHYLLA sp. nov. 
Arbor glabra ; foliis crassissime coriaceis, nitidis, oblongis, 
usque ad 11 cm longis, 3 ad 5.5 cm latis, basi acutis vel acumina- 
tis, apice acute acuminatis, margine valde revolutis; capsulis 
axillaribus, solitariis, breviter pedunculatis, ovoideis, circiter 1 
cm longis. 
A glabrous tree, size not indicated. Branches terete, pale- 
olivaceous, the branchlets slender, somewhat sulcate on two sides. 
Leaves oblong, very thickly coriaceous, 9 to 11 cm long, 
3 to 5.5 cm wide, narrowed below to the acute or somewhat 
acuminate base and above to the sharply acuminate apex, the 
margins strongly recurved, both surfaces shining, the lower 
usually a little paler than the upper; lateral nerves slender, up 
to 30 on each side of the midrib, irregular, sometimes rather 
indistinct and confused with the secondary ones and the reticula- 
tions; petioles 5 to 7 mm long. Peduncles solitary, axillary, in 
fruit 5 mm long or less, with numerous, spreading bracteoles, 
the lower ones smaller than the upper. Flowers not seen. 
Capsules ovoid, about 1 cm long, solitary, smooth, somewhat 
glaucous-purple when dry.
