The isosceles triangles converge upwards, with its apexes towards the centre. Bases are attenuate while apexes are acute, acuminate, or obtuse. The apexes are acuminate to sub-acuminate. The leaf shape varies from ovate to obovate with acute bases and obtuse apexes. The middle and upper leaves are linear-lanceolate with pointed apexes. The flowers are on simple inflorescences that emerge from leaf apexes. The apexes of the anion plot are sulfate, chloride and carbonate plus hydrogen carbonate anions. These form 24 octahedral pyramids (half-16-cells) with their apexes at the center. The entire circuit was repaved and the concrete patches in the turn apexes were removed. The apexes of the cation plot are calcium, magnesium and sodium plus potassium cations. Snow Dome () is one of two hydrological apexes of North America. Occasionally, leaf apexes are acute or emarginate. On one of the seven apexes remains a pub, "The Crown". At one stage, each of the seven apexes facing the column housed a pub. Following the 1996 Brickyard 400, the apexes of the four turns were breaking up.
