cell, at a point where the seed is suspended a little below its apex. On the other hand, 
in Rhaphithamnus the fruit is a globular drupe of a fine deep blue colour, with a very 
thick pulpy pericarp, formed by the subsequent adhesion of the calyx to the ovary, its 
presence being now only perceptible by the five small teeth which form the margin of 
the umbilieated hollow in the apex of the drupe; it contains two suborbicular nuts, 
convex and smooth outside, flat on the adjoining faces, and rounded on the margins, 
separated by the fleshy axile columella; these are dark and of corneous consistence, 
2-celled, and marked at the base, within each margin, by a deep hollow depression, 
whence, by means of a small perforation, a chord of nourishing vessels enters through 
the base of each cell, in communication with the laterally ascending raphe, so that the 
seeds here are quite anatropous, not semianatropous as in Citherexylon. The name of 
the genus is derived from padic (acus), 8áuvoc (frutex), from the long slender, needle-like, 
flower-bearing spines.
