1. VERBASCUM L. 



Annual, biennial or rarely perennial caulescent herbs, often glandular or densely 

 pubescent. Leaves alternate : blades entire, toothed or pinnatifid, soiuelimes decurrent 

 on the stem. Flowers in terminal spikes, racemes or panicles. Sepals 5, partially united. 

 Corolla white, yellow or purple, rotate : lobes 5, slightly unequal, the upper one exterior 

 in the bud. Stamens 5, exserted, the upper 3, or all of the filaments pubescent : anther- 

 sacs confluent. Ovary 2-celled, sessile : styles dilated or flattened at the apex. Ovules 

 numerous. Capsule oblong to subglobose, septicidally 2-valved : valves usually cleft at 

 the apex. Seeds rugose, wingless. Our species bloom in the summer and fall. Mullen.
