longer than the calyx and gaping, with a short turned-back tube, and 

 the throat long, with hollow upper lip, the lower lip ending in a notch. 



Skull-cap is 2-3 ft. high. The flowers may be met with from June 

 to September. It is perennial, and propagated by division. 



The tube of the corolla is long, smooth inside, with an expanded 

 throat as in other long-tubed labiates. The upper lip is 3-lobed and 

 has a small surface adapted to butterfly visits, the lower dilated with 

 spreading lateral lobes. The opening between the two lips is large 

 enough for humble bees. There are 4 anthers. The anthers are in

pairs and ripen first, fringed with hairs to hold the pollen, with i cell in 

 the lower, 2 in the upper. The style has a short upper lobe, and both 

 it and the stamens are included. There are complete flowers, and 

 others with the anthers undeveloped. They may be on the same or on 

 different plants. Skull-cap is visited only by the Brimstone, Rhodocera 

 rhamni. 



The nutlets fall when ripe automatically just around the parent 

 plant. The calyx on the fading of the corolla closely envelops the 

 ovary and protects the seeds, being a helmet-like hood. 



This is a peat-loving plant, requiring a moist humus soil or peat soil. 



A beetle, Phyllobrotica quadrimaculata, and a moth, Choreutis 

 scintillullana, are found upon Skull-cap.
