BONATI—PHTHEIROSPERMUM AND PEDICULARIS. 137 
It differs from P. pseudostenocorys, Bonati, which also has 
only one tooth+on each side of the lower margin of the hood, 
by :—(1) its habit, the form of its leaves, the colour of its cor- 
olla; (2) the form of its calyx; (3) its staminal filaments all 
glabrous ; (4) the lower lip with lateral lobes crenulate and slightly 
ciliate. 
The series of the Lyratae to which I again attach the Ternatae 
separated in error in 1910, contains now 6 species which can be 
arranged as follows :—
