Linnea borealis L. Twin Flower. 
One of the most attractive of June flowers is the twin flower, 
Linnea borealis L., named after Linnzeus, with whom it was a 
special favorite. It extends throughout the eastern Northern 
States, from Newfoundland and through British America, 
Alaska, Siberia, and northern Europe to England. It is a 
trailing evergreen vine densely carpeting the ground in cold, 
open woodlands. The nodding pinkish blossoms are borne in 
pairs at the summit of elongated peduncles, and exhale a sweet, 
vanilla-like fragrance. The funnel-formed corolla is five-lobed, 
nearly regular, though the two superior lobes are slightly 
larger. The tube is 8 mm. in length, and for 3 mm. is very 
small. The inverted position of the flower excludes rain. The

is secreted on the same side, at the base of the corolla, between
