Leaves are lanceolate to ovate, coarsely toothed, the lower leaves having petioles, the upper leaves clasping. The leaves form as a rosette the first year. Inflorescences are terminal one-sided, racemes or spikes. Flowers are showy, funnel shaped, 5-6 lobed, greenish to yellow in color with a distinct pattern of purple colored veins (Figures 213 and 214). Fruits are urnshaped capsules enclosed by calyces, and containing many seeds (Figure 215).
