the base by a few scales ; stamens in ternate whorls, with oval connectives. 

 Pistillate branchlets, composed of five to eleven ternate whorls of scales, with 

 usually only the apical whorl fertile, each of its scales alternating with one 

 of the three ovules, the tips of which protrude at the apex of the branchlet. 

 Fruit, composed of three or six scales, marked at the apex by three radiating 

 lines or furrows. Seeds, normally three, free and radially disposed in the 

 centre of the berry, with depressions for large resin-glands.
