Angelonia salicariifolia

Angelonia salicariifolia is an upright plant with a somewhat woody base, native from Bolivia through Brazil to northeastern Argentina. The stems are hairy and carry opposite, pointed leaves. Violet flowers open singly where the upper leaves meet the stem, making the flowering shoot look like a loose spike. Each corolla has two lips with rounded lobes and a recessed throat with a short, divided projection. The rounded fruit is a capsule. Photographed in Colombia.
