Discussion:
Supplement: The specimens cited or described in this supplement were received after the publication of Parts I and II. Aphelandra pinarotricha is somewhat like A. phlogea from the Department of Magdalena, but that species has a glandular pubescence, and much larger leaves, flowers and bracts. Its stems are glabrous. The specific epithet is from the Greek πιναρός, sordid, and θρίξ, hair.
