OCHNACEAE 



OURATEA Aublet 

 OURATEA MINDANAENSIS sp. nov. 



Arbor parva, glabra; foliis oblongis, coriaceis, 7 ad 11 cm 

 longis, basi rotundatis, apice acutis vel leviter acuminatis, dis- 

 tincte serratis, dentibus tenuiter apiculatis, nervis primariis 

 quam secondariis baud distinctioribus ; inflorescentiis termi- 

 nalibus, floribus umbellatim dispositis, umbellis 2 vel 3; sepalis 

 3 vel 4, ellipticis ad oblongo-ellipticis rotundatis, 6 ad 7 mm 

 longis ; staminibus 8 ad 10, antheris 3 mm longis. 



A small glabrous tree, about 4 m high, the branches brownish, 

 slender, terete. Leaves oblong, coriaceous, 7 to 11 cm long, 2 

 to 4 cm wide, the base rounded, apex acute to somewhat acu- 

 minate, margins distinctly toothed, the teeth slenderly apiculate, 

 pointing upward, the upper surface brownish-olivaceous and 

 strongly shining when dry, the lower surface paler and slightly 

 shining; primary lateral nerves scarcely more distinct than are 

 the secondary ones, curved, not prominent, anastomosing, and 

 forming 1 or 2 more or less distinct marginal nerves; petioles 

 up to 5 mm in length. Inflorescences terminal, consisting of 2 

 or 3 peduncled, umbellike cymes, the peduncles less than 1 cm 

 long, the bracts oblong, about 2.5 mm in length. Flowers few, 

 their pedicels up to 1.5 cm long. Sepals 3 or 4, elliptic to oblong- 

 elliptic, rounded, 6 to 7 mm long. Petals similar to the sepals 

 but thinner, usually 3 or 4. Stamens 8 to 10, their filaments 1 

 mm long, the anthers linear, 3 mm in length. 



Mindanao, Surigao Province, Bur. Sci. 34479 Ramos & Pas- 

 casio, April 25, 1919, along streams at low altitudes at the iron 

 deposit on the northeast coast. 



In general this species is similar to Ochna fascicularis Blanco, 

 but by definition it belongs in the genus Ouratea and may be 

 readily distinguished from Blanco's species not only by its floral 

 characters but also by its distinctly and sharply toothed leaves 

 which are rounded at the base.
