Introduction to Vascular Plants
Species Information
General:
Biennial herb from a taproot; stems single, erect, 0.5-1.5 m tall, angled, stalked-glandular upward especially in the inflorescence, smooth below.
Leaves:
Basal leaves in a rosette, broadly lanceolate to oblong, 5-25 cm long, tapering to a short-stalked base, coarsely toothed and sometimes also wavy-lobed; stem leaves numerous, alternate, progressively reduced upward, becoming unstalked, with clasping leaf-bases, the margins with sharp triangular teeth.
Flowers:
Inflorescence a rather open, bracted, spike-like, terminal cluster, occasionally with additional axillary clusters, of numerous stalked flowers, the stalks 8-15 mm long; corollas yellow or less commonly whitish, wheel-shaped, 2-3 cm across, 5-lobed, the lobes nearly equal, the tube very short; calyces glandular-hairy, much shorter than the flower stalks, deeply 5-lobed, the lobes narrowly elliptic; stamens 5, the filaments covered with purple-knobbed hairs.
Fruits:
Capsules, nearly globe-shaped, 6-8 mm long; seeds numerous, longitudinally ridged.
