New Ireland; near the junction of the Niagara and Weitin River (coil, site 
2); mature lowland rainforest, in/near transect 1; elev. 240 m, centered 
on coordinates 152 deg 56’ 242” E x 4 deg. 30.210’ S. 
with coll sequence starting Horsfieldia 9895; shrub/treelet, common 
along forest edges (e.g. streambeds); stems terete, lenticels muricate; 
leaves alternate, spiral, imparipinnate, to 1 .2 m or +, entirely glabrous; 
petiole and rachis terete, smooth shiny green except for brown corky 
lenticels at swollen base of petiole; leaf sheath elongate (>1/4 length of 
petiole); leaflets coriaceous to papyraceous, adaxially glossy dark green, 
abaxially shiny medium green, blades lanceolate-oblong, to 27 cm x 12 
cm, apex shortly and abruptly acuminate, margins entire, base truncate; 
petiolules to 3 cm, the insertion to the rachis swollen; venation 
penninerved, laterals about 6-9 unevenly spaced pairs, reticulum fine 
and irregular; infructescence terminal, paniculiform, somewhat arching, 
about 1 15 cm length, pedunculate, all axes smooth and glabrous, usually 
swollen at the junctions, branching pattern verticellate, ending in 
umbellules, pedicels distinctly articulate at the drupe; developing fruit 
globose, epicarp purple, summit with a calycine rim irregularly truncate 
sometimes denticulate; styles free, diverging or recurved, 3-5, the 
number of cells in the fruit equalling the number of styles; flowers not
