xi, c, i Merrill: Plants from Sorsogon Province, Luzon 31 



Here I also refer tentatively Bur. Sri. 23U1S 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. 



SYMPLOCACEAE 



SY MP LOCOS Jacquin 

 SYMPLOCOS ACUMINATISSIMA sp. nov. § Bobua. 



Arbor glaberrima vel inflorescentiis parce pubescentibus ; f oliis 

 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 ; f ructibus 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. 

 Sri. 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.
