Having a sharp point; tapering to a peak or apex; characterized by being pointed or peaked.
From Latin 'cacumen' (summit/point) combined with '-ous' (full of/characterized by). This adjectival form describes objects or shapes that are prominently pointed or peak-like.
Cacuminous mountains and cacuminous leaves are separated by millions of years of evolution, yet both share a mathematical property—their pointed peaks maximize surface area for roots and minimize it for erosion, proving geometry rules nature across scales.
