Flowers are, however, also found, which have a relatively 

 much larger pistil, with a stigma reaching above the limb 

 of the corolla, for instance fig. G; I found the most protruding 

 style in the flower illustrated in fig. H ; the pistil is of about 

 the same length as the one in fig. G, but the corolla tube 

 is noticeably shorter, causing a larger portion of the style 

 to protrude ; the anthers in fig. H were not yet open. I have, 

 however, never met with a short-styled flower, the anthers

of which corresponded in height with a stigma protruding 

 to such extent. Finally, I have seen a plant at Kåfjord, 

 with anthers and stigma at about the same level, as illus- 

 trated in fig. jP; the calyx was here unusually short; the 

 stigma was level with the tip of the anthers, showing its 

 greater part above these; the anthers were open and full of 

 pollen, and germinated pollen was found on the stigma. This 

 was large and its papillae were in size just between those 

 in the common long- and short-styled flowers (see fig. F, to
