prominent nerves and slender reticulations brown ; lateral nerves 

 about 16 on each side of the midrib, very prominent on the 

 lower surface, somewhat curved, anastomosing near the mar- 

 gins; petiolules 2 to 5 mm long. Panicles terminal and in 

 the upper axils, brown when dry, very slightly pubescent, 

 in fruit up to 40 cm long. Immature fruits obovoid, 1 to 

 1.5 cm long, externally densely covered with a short, dense, 

 brownish-purple indumentum, the persistent petals oblong, 

 pubescent, 4 mm long. Staminal tube very short, 0.5 mm long 

 or less, the filaments flattened, ciliate-pubescent, about 1.5 mm 

 long, obtuse, the anthers 0.5 mm in length. 



Mindanao, District of Zamboanga, near Margosatubig, in hill forests, 

 For. Bur. 13764- Foxworthy, DeMesa, & Villamil, May 11, 1912, altitude 

 about 120 meters, and locally known to the Moros as sasd. 



A very distinct and characteristic species, readily distinguished from 

 all previously described ones by its 7-foliolate leaves and its short staminal 

 tubes. 



BUXACEAE 



BUXUS Linnaeus 



BUXUS RIVULARIS sp. nov. § Eubuxus. 



Frutex circiter 1 m altus, glaber; foliis coriaceis vel sub- 

 coriaceis, lanceolatis, usque ad 5 cm longis, utrinque subaequaliter 

 angustatis, apice acute acuminatis, basi acutis; racemis axillari- 

 bus, solitariis, 1 ad 2 cm longis. 



A shrub about 1 m high, glabrous, the branches slender, light- 

 gray, terete, the branchlets distinctly angled. Leaves lanceolate, 

 2.5 to 5 cm long, 5 to 12 mm wide, rather pale when dry, of 

 about the same color and slightly shining on both surfaces, 

 subequally narrowed to the acute base and to the sharply acum- 

 inate apex, subsessile or very shortly petioled, often a little fal- 

 cate; nerves very faint, anastomosing in a distinct marginal 

 nerve. Racemes axillary, solitary, 1 to 2 cm long, glabrous, male 

 flowers below, the terminal flower usually female, the pedicels 

 about 3 mm long, the bracteoles ovate, acute, 1 mm long. Male 

 flowers: Outer two sepals lanceolate, acuminate, about 2.2 mm 

 long, 1 mm wide, the inner two as long but ovate or oblong-ovate, 

 acute, 1.5 mm wide. Filaments about 2.5 mm long. Rudimen- 

 tary ovary depressed-globose, entire. Female flowers at the 

 end of the raceme bearing the male flowers. Bracteoles linear- 

 lanceolate, the outer 2 sepals ovate, a little longer than the inner 

 four which are broadly ovate, acute, 2.2 mm long, slightly ciliate- 

 pubescent, all slightly accrescent in fruit, persistent, and abput 

 3 mm long. Ovary glabrous. Young fruit ovoid, glabrous, 5
