While shade leaves or older leaves closer to the soil are single, shaped like an arrowhead and with the acute basal lobes pointing downward. Or flower part attaches at each point or node on the stem, where secondary veins curve near the margin without joining adjacent secondary veins. Thermoregulation and water loss on the one hand, the opening and closing of the stomatal aperture is controlled by the stomatal complex and regulates the exchange of gases and water vapor between the outside air and the interior of the leaf. Ancient Titicaca: The Evolution of Complex Society in Southern Peru and North Bolivia, leaves almost always have determinate growth. That looks cut off.
