This species has somewhat the appearance of Dysoxylum 
turczaninowii C. DC. but is not closely allied to that species, 
differing essentially in its simple, spicate inflorescences; the 
leaflets are also much smaller than in the latter species. 
DYSOXYLUM SI ARGAOENSE sp. nov. § Eudysoxylum. 
Arbor parva, partibus junioribus et inflorescentiis caulinis 
plus minusve pubescens; foliis alternis, circiter 35 cm longis, 
vetustioribus glabris, foliolis circiter 13, chartaceis, oppositis, 
oblongis ad oblongo-lanceolatis, plerumque inaequilateralibus, 
10 ad 15 cm longis, acuminatis, nervis utrinque circiter 15, 
tenuibus; racemis caulinis, fasciculatis 1.5 ad 2.5 cm longis; 
floribus 4-meris, breviter pedicellatis, 5 mm longis, calycis cir- 
citer 2 mm diametro; petalis oblongis liberis, glabris; ovario 
pubescente. 
A small tree, the younger parts and the cauline inflorescences 
more or less pubescent. Branches terete, brownish when dry, 
the ultimate ones about 7 mm in diameter, glabrous, the branch- 
lets and very young leaves more or less pubescent. Leaves 
alternate, about 35 cm long, glabrous when mature, the leaflets 
about 13, opposite, chartaceous, oblong to oblong-lanceolate, 
usually inequilateral, olivaceous when dry, 10 to 15 cm long, 
3.5 to 4.5 cm wide, acuminate, the base usually strongly in- 
equilateral and acuminate, the lamina longer on one side than 
on the other, or the uppermost leaflets equilateral ; lateral nerves 
about 15 on each side of the midrib, slender and anastomosing, 
the reticulations lax, distinct ; petioles 6 mm long or less. 
Racemes fascicled on the larger branches, 1.5 to 2.5 cm long, 
cinereous-pubescent. Flowers 4-merous, about 5 mm long, their 
pedicels 1.5 to 2 mm in length. Calyx pubescent, somewhat 
cup-shaped, about 2 mm long and wide, broadly and irregularly 
4-toothed. Petals 4, white, free, oblong to oblong-oblanceolate, 
about 5 mm long, 1.5 mm wide, glabrous or slightly pubescent
