Scrophulariaceae.

twisted in such a manner that its two-toothed tip turns 

 somewhat to the right (E). The ridge reaches the edge slightly 

 above the beginning of its revolute portion {A and G). The 

 slit between the two edges of the upper lip is usually rather 

 narrow. The front filaments are sparingly hairy. The stigma 

 protrudes more or less above the two teeth (5, D, E and H). 



Fig. 28. Pedicularis euphrasioides. 

 (From Greenland; about 67° N. lat.) 

 A, B, A flower seen from the left and the right side; in A the position 

 of the style and the stamen is indicated. C, Stigmatic papillæ. D, A 

 flower in front view. E, The upper lip seen in front view. F, The 

 ovary. G, The upper lip seen in side view; the venation is indicated. 

 H shows the same as A. I, Transverse section of ovary. (Drawn by 

 E. Warming, 1890.) 



Judging from the structure of this almost horizontally- 

 placed flower {A and Б), I must assume that it is only with 

 difficulty that it pollinates itself. It produces ripe fruit in 

 Greenland at 67° N. lat." 



Geographical Distribution. West Greenland be- 

 tween 62° (but only in a few localities south of 64° N. lat.)
