Cereus Triangularis — Night-Blooming Cereus
Although this plant with its wonderful nocturnal blossoms may be found growing almost everywhere in the Islands, the best specimens of its kind may be seen on the stone walls of Oahu College. The beautiful creamy flowers with their yellow centers are large, about a foot long, and when in full bloom about the same in diameter. The tube is covered with large, leaf-like green scales. The fruit, which is about 3½ inches long and 2 inches in diameter, is covered with persistent, large, fleshy scales which are scarlet colored when ripe, and the interior pulp is edible and refreshing. Fruit, however, upon the night-blooming cereus in Hawaii is rather rare, although a few fine specimens have matured.
