xi, c, i Merrill: Plants from Sorsogon Province, Luzon 31 
Here I also refer tentatively Bur. Sci. 23413 Ramos, from Mount Lalao, 
Province of Sorsogon, Luzon, which differs from Diospyros ulo as above 
described in its leaves being brownish when dry, more strongly shining, 
the very young branchlets and petioles slightly pubescent, and the immature 
fruits entirely glabrous and shining, brown, not black in color, when dry. 
It is possible that this Sorsogon plant represents a distinct species, but 
additional material is desirable before attempting to separate it.

Arbor glaberrima vel inflorescentiis parce pubescentibus ; foliis 
lanceolatis, longe tenuiter caudato-acuminatis, usque ad 11 cm 
longis, chartaceis ad subcoriaceis, nitidis, basi acutis, margine 
irregulariter undulato-crenatis, nervis utrinque 8 ad 10, distan- 
tibus, anastomosantibus ; racemis in axillis superioribus, soli- 
tariis, usque ad 6 cm longis, junioribus leviter pubescentibus, 
vetustioribus glabris ; fructibus anguste ovoideis, obtusis, circiter 
8 mm longis. 
A tall tree, quite glabrous or the inflorescence at anthesis 
and in young fruit sparingly pubescent. Branches slender, 
terete, smooth, brownish, the branchlets similar but more slender. 
Leaves numerous, somewhat crowded on the ultimate branchlets, 
lanceolate, 7 to 11 cm long, 1 to 2.5 cm wide, yellowish green 
when dry, chartaceous to subcoriaceous, shining, gradually nar- 
rowed into the long, slender, blunt, caudate-acuminate apex, the 
acumen up to 3 cm in length, the base acute, the margins 
irregularly undulate-crenate ; lateral nerves 8 to 10 on each side 
of the midrib, slender, anastomosing, the reticulations lax ; 
petioles 1 to 1.7 cm long. Racemes in the upper axils, mostly 
solitary, simple, up to 8 cm in length, when young appressed- 
pubescent, in age perfectly glabrous. Fruit narrowly ovoid, 
terete, smooth, obtuse, brownish when dry, about 8 mm long. 
Luzon, Province of Sorsogon, Bulusan Volcano, Bur. Sci. 23690 Ramos 
(type), September 5, 1915, in the mossy forest. Here I also refer Bur. 
Sci. 23333 Ramos from Mount Bagacaua, Sorsogon; perhaps Wenzel 888, 
determined as S. villarii Vid., also is referable here. 
The alliance of this species is with Symplocos villarii Vid. (S. polyandra 
Brand, but not Guettarda polyandra Blanco), from which it is distin- 
guished by its lanceolate, very long, and slenderly caudate-acuminate 
leaves.
