furrow between them; in В the slightly oblique lower lip 

 should be noted and the wide slit (as much as 2 mm) between 

 the two revolute portions of the edge of the upper lip: here 

 the stigma protrudes just beyond the tip of the helmet, С 

 shows the curving of the upper part of the style, in E is 

 seen its natural and usual position in relation to the helmet 

 and anthers. A flower of somewhat different structure is 

 shown in /: there the style is shorter, less curved, and does 

 not reach down underneath the anthers, D and F are opened 

 anthers, G stigmatic papillæ and H germinating pollen-grains. 

 Honey is secreted by the three-lobed swelling on the front 

 of the oblique ovary {P). 



Peloria may occur: such a flower is shown in N\ there 

 the corolla is irregularly 6-lobed, the stamens are of equal 

 length, and the style protrudes far, and is erect. 



In very small-flowered specimens brought by Nathorst 

 from Spitzbergen, E, Warming found as close contact of 

 stigma and anthers, as shown in 0. 



"The corolla is of a pale rose-colour, with darker throat 

 and tip of helmet, more seldom the colour is pure white 

 (for instance in Upernivik). The flower is set almost hori- 

 zontally. The corolla-tube is , , , . 7 — 8 mm long; the total 

 length of the flower is about 13 — 14 mm. Slight protogyny 

 appears to occur, and the stigma probably protrudes some- 

 what more in the younger flowers than later on, so that 

 cross-pollination may perhaps take place in these" (E. War- 

 ming, 1890, p, 213), According to information given by M. 

 PoRsiLD it is common in Northern Greenland for the corolla 

 to be of a whitish shade or, at any rate, of a pale pink colour, 

 Ekstam records this species from Nova Zembla as scentless, 

 but from Spitzbergen, as having a strong perfume. Like all 

 the species of Pedicularis mentioned here, it must be assumed 

 originally to have been adapted to pollination by humble-
