tubular, 2-lipped, the upper lip notched, lower larger and 3-lobed. Stamens 



included. Ovary 1-celled, forming a simple akene in the calyx. Herb. 



2. VEEBENA. Flowers in spikes or heads. Calyx tubular or prismatic, 5-ribbed 



and plaited. Corolla salver-form, the tube often curved, the border rather
