The corolla is some- what peculiar. It has somewhat the ap- [)earance of a wide open mouth, and is known as a lahiatf or two-lipped corolla. Tlio upper li}) is erect, and notched at the apex. The lower lip spreads outward, and consists of a large central lobe and two small lateral ones. Altogether, therefore, there eu'ejirr lobes tutiiig the gamopetftious corolla. Pull out the corolla, and with the point of your needle split its tube in front. On laying it open, the stamens will be found to bo in- serted upon it (epipetalous). They are four in number, two of them shorter than the other two. Hence they are described as didtjnumous.

The pistil consists of a two-lobed stigma, a , long style, and an ovary which seems at first | as if made up of four distinct cai^els (Fig. 59). But the single style and the two-lobed stigma will warn you against this supposition. The ovary really consists of tuo carpels, each of two deep lobes, and, as the seeds ripen, these lobes form four little nutlets (Fig. 60), each contain- p^^ 59^ ing a single I'I I,.
