branchlets terete, unarmed, the former grayish, rugose, the latter 

 smooth, nearly black. Leaves alternate, about 15 cm long, the 

 rachis canaliculate, somewhat angled, armed on the lower side 

 with few, scattered, rather stout, recurved, 1 to 1.5 mm long 

 spines. Leaflets 7, coriaceous, lanceolate to ovate-lanceolate, 

 entire, opposite or subopposite, 3.5 to 7 cm long, 1.2 to 2.6 cm 

 wide, shining, olivaceous-brownish when dry, the glands not 

 prominent, narrowed below to the acute and sometimes slightly 

 inequilateral base, and above to the slenderly but obtusely acumi- 

 nate apex; lateral nerves 7 to 9 on each side of the midrib, dis- 

 tinct on the lower surface, anastomosing, the reticulations lax; 

 petiolules 2.5 to 4 mm long. Panicles axillary, narrowly pyra- 

 midal, about 4 cm long, sparingly pubescent, the primary 

 branches about 5 mm long. Cocci subelliptic, brown and rugose 

 when dry, about 5.5 mm long, keeled but scarcely compressed, 

 obliquely beaked at the apex, 1-seeded, sessile, but one or two 

 developing from each ovary.

This species is apparently represented by Cavalerie 950 from Kouy- 

 tcheou, which has been identified with Zanthoxylum oxyphyllum Edgw., 

 but to which species I do not consider that it can possibly be referred. It 

 is well characterized by its few leaflets, which are entire and slenderly 

 acuminate; its unarmed branches and branchlets; and its short, axillary, 

 very narrow panicles.

 180 meters. 



I have transferred this species to Epirixanthes Blume, as I consider 

 this group to be generically distinct from Salomonia.
