336 PHANEROGAM I A. 



chartaceous. In one specimen the apex has separated into four 

 points, so that it is perhaps four-valved at complete maturity : if so it 

 would seem to be septicidal. The fruit is closely sessile in the calyx ; 

 but its base is marked with the vestige of a very short gynophore, 

 like that of A. Richii. Seeds amphitropous, large, when solitary 3 

 lines long and filling the cell, somewhat club-shaped, the lower, cha- 

 lazal end being prolonged and tapering ; when two in each cell, the 

 upper is ascending and the lower, probably imperfect one, is descend- 

 ing : testa rather drupaceous, with a thin and somewhat dull exterior 

 pellicle, and a very thick and crustaceous inner portion. Nucleus 

 small in proportion to the size of the seed, consisting of a sparing 

 fleshy albumen, and a straight embryo of nearly its length. Cotyle- 

 dons oblong. Kadicle superior. 



This is doubtless a true congener of Acronychia Icevis, Forst., of 

 New Caledonia, and of A. Midlic7ieri, Schott (Vepris &implicifolia, 

 Endl.) of Norfolk Island. So far as can be judged from the brief 

 character, the species bears more resemblance to Blume's A. arborea 

 than to any other.
