trinacriform

1. (rare) Having three prongs or sharp points.Examples: "However, it differs from the latter in often having trinacriform bracteoles, elliptic to suborbicular fruits 5-6 long mm and 4-4.5 mm wide, solitary vittae in the lateral furrow and 4 on the commissure, 5-toothed calyx, and oblong purplish petals."; "The high steric hindrance induced by the high carbon sugars and trinacriform architecture required that the core undecasaccharide was synthesized through a finely tuned linear assembly [2 + (1 + (3 + (1 + (1 + 3))))] rather than convergent strategies."not-comparablerare
