8 to 10 mm long, the anthers opening by terminal pores. Car- 

 pels 5, slightly hirsute, 7 mm long, oblong, subcyhndric; styles 

 5, about 1 cm long; ovules about 16, 2-seriate. Fruit not seen. 



Palawan, Taytay, Merrill 9237 (type), flowering from April 10 to June 

 and probably later, 1913; Malampaya Bay, Bur. Sci. 21555 Escritor, August,

This species is common at low altitudes in northern Palawan, growing 

 in thin, second growth forests, and in and along the borders of open cogo- 

 nales, that is, areas occupied by the cogon or lalang grass {Imperata cylin- 

 drica) . It is, perhaps, most closely allied to the Malayan Dillenia pulchella 

 (Jack) Gilg, and among the Philippine species to Dillenia sibuyanensis 

 (Elm.) (Wormia sibuyanensis Elm,). Its solitary flowers, together with 

 its somewhat decurrent laminae and its few carpels are striking differential 

 characters. 



LECYTHIDACEAE 



BARRINGTONIA Forster 

 BARRINGTONIA PTERITA sp. nov. 



Arbor parva, glabra; foliis ad apices ramulorum plus minusve 

 confertis, oblanceolatis, sessilibus vel subsessilibus, usque ad 40 

 cm longis, acuminatis, basi sensim angustatis; racemis circiter 

 70 cm longis, pendulis; fructibus oblongis, 6 cm longis, longi- 

 tudinaliter 4-alatis. 



A small glabrous tree, 10 m high fide Ramos. Branches terete, 

 the ultimate ones about 6 mm in diameter, above with rather 

 prominent petiolar scars. Leaves somewhat crowded at the ends 

 of the branchlets, oblanceolate, 20 to 40 cm long, 4 to 8 cm 

 wide, entire, rather pale when dry, somewhat shining, charta- 

 ceous, the apex rather sharply acuminate, gradually narrowed 

 from above the middle to the base, the base 1 cm wide or less, 

 then abruptly acute or rounded, the petiole none, or stout and 

 4 mm long or less; lateral nerves about 20 on each side of the 

 midrib, rather prominent on the lower surface. Racemes pend- 

 ulous, about 70 cm long, the flowers unknown. Fruit oblong 

 or narrowly oblong, 6 cm long, 1.5 to 2.5 cm wide, the base acute 

 the pedicels about 1 cm long, the persistent sepals crowning the 

 apex about 1 cm in length, the four angles longitudinally winged, 

 the wings subcoriaceous, about 5 mm wide. 



Luzon, Province of Laguna, Dahican River back of San Antonio, Bur. 

 Sci. 15121 Ramos, June, 1912. 



A species manifestly allied to Barringtonia racemosa Blume, but at once 

 distinguishable by its prominently longitudinally 4-winged fruits, in this 

 character differing from all the previously known Philippine species. Elmer 

 9168 from Lucban, Tayabas Province, is undoubtedly a small leaved form 

 of the same species; it was distributed as Barringiorria racemosa Blume.
