À beautiful evergreen tree, 15 to 20 feet high, much branched, conspicuous for its 
numerous bright green leaves, accompanied by golden spines and lilac flowers, inter- 
mixed with blue shining drupes. It is called by the natives Arrayan espinudo (Prickly 
Myrtle). The decussating axils are 3-1 inch apart, the horizontally spreading branchlets 
gradually diminishing upwards: the leaves are 8-10 lines long, 6-8 lines broad, on a 
petiole 1 line long; the spines are 10-18 lines long, and stand at a complete right angle. 
The flowers are in an opposite pair upon each spine, or in a 3-flowered extremely short 
pubescent raceme, in each opposite axil; the pedicels are 1 line long; the subpilose 
calyx is 2 lines long, with five equal short triangular teeth; the tube of the corolla is 
6 lines long, the lobes of the border 13 line long and subpilose inside; the longer pair of 
filaments are 4 lines, the shorter pair 3 lines, the sterile one 2 lines long; the ovary, 
style, and stigma are 6 lines long: the drupe, when fully ripe, is 3 inch in diameter; 
the nueules are 3 lines long and broad, of very thick corneous consistence, and each 
2-celled, two depressions are seen at the base of their internal face near the margin, 
where the perforation leading into the bottom of each cell is distinctly visible, communi- 
eating with the raphe of each seed, and which ascends along the external angle or each 
cell; the integuments are very thin and membranaceous; the embryo, destitute of 
albumen, has fleshy cotyledons with a much smaller inferior radicle.
