ovary. Ovary ovoid, inequilateral, glabrous. Fertile stamen 1, 

 the filament 3 mm long; staminodes 3, very slender, 0.5 mm 

 long or less. Immature fruits ellipsoid, 2 cm long, glabrous, the 

 seed compressed and apparently smooth. " 



Luzon, Zambales Province, Masinloc, Merrill 294,6, May, 1903, 

 For. Bur. 27169 Maneja & Bawan (type). May, 1918. To this 

 species I also refer For. Bur. 25497 Cruz from Lanao Dis- 

 trict, Mindanao, although this specimen differs from the type 

 in its very slenderly acuminate leaves. 



Among the Philippine species the present one is most closely 

 allied to Mangifera monandra Merr., from w^hich it is distin- 

 guished by its much smaller leaves, smaller flowers, and pubes- 

 cent inflorescences. It belongs in the group with M. quadrifida 

 Jack.

 basi rotundatis ad late acutis, in siccitate brunneo-olivaceis, sub- 

 tus pallidioribus, nervis utrinque 5 vel 6, curvato-adscendentibus, 

 perspicuis; paniculis axillaribus terminalibusque, 12 ad 15 cm 

 longis ; floribus circiter 7 mm diametro, calycis 5-angulatis, lobis 

 brevissimis, acutis, petalis ovatis, obtusis, 3 mm longis, longitu- 

 dinaliter cristatis, junioribus apice leviter fimbriatis, vetusfiori- 

 bus integris. 



An entirely glabrous tree about 10 m high, the branches and 

 branchlets purplish-black when dry, somewhat rugose. Leaves 

 coriaceous, oblong-elliptic, entire or the margins obscurely un- 

 dulate, 10 to 16 cm long, 5 to 8 cm wide, the apex with a broad, 

 short, obtuse acumen, the base rounded to broadly acute, the 

 upper surface when dry brownish-olivaceous, the lower paler; 

 lateral nerves 5 or 6 on each side of the midrib, curved-ascending, 

 obscurely anastomosing, prominent on the lower surface, the 

 reticulations slender; petioles 1 to 2 cm long. Panicles axillary 

 and terminal, 12 to 15 cm long. Flowers white, about 7 mm in 

 diameter, their pedicels up to 4 mm long, the bracteoles lanceo- 

 late, acuminate, about 0.6 mm long. Calyx about 4 mm in 

 diameter, 5-angled, the lobes short, acute. Petals ovate, obtuse, 

 3 mm long, the younger ones slightly fimbriate at their apices, 

 the older ones entire, longitudinally cristate on the inner face.
