LILY FAMILY. Lfllaceae. 



Streptopus A species similar to S. roseus, and found 



longipes only in the woods of Marquette Co., Michi- 



gan. Leaves pale green beneath, fine-hairy on the edges, 

 and stemless. Flowers bell-shaped, magenta-pink. 12-16 

 inches high, the stem fine-hairy above, the rootstock 

 slender, and outspread. 



Twisted Stalk The leaves, strongly clasping the zigzag 

 Streptopus stem, are smooth and light green, with a 

 amplexifolius w hitish bloom beneath. The curly-se- 

 ** paled, greenish flower is about J inch 



May-July wide, and hangs by a long, crooked, 



threadlike stem from beneath the leaves. 

 The flower is perfect and regular, with six lance-shaped 

 sepals, and is either solitary or (rarely) in pairs. The 

 name is from the Greek, for twisted, and stalk or foot. 

 The usually solitary berry is red, round, and nearly 

 inch in diameter. 2-3 feet high. Cold moist woods. 

 Me., west to the Rockies, and south to N. C., in the 

 mountains. 



Streptopus Differs from the preceding in its dull 



roseus purple-pink flower, its leaves which are not 



Dull purple- whitened with a bloom beneath, but are 

 Ma -earl altogether green and finely hairy at the 



j u iy edge, and its earlier period of bloom. 



1-2-J feet high. In the same situations, 

 but extending farther south to Ga. , and west to Ore. 



The genus Streptopus is dependent in part upon insects 

 for cross-fertilization. Some of the most frequent visit- 

 ors are the bumblebees, the beelike flies Bombylius, and 

 the bees of the genus Andrenidce, still, their effect upon 

 the flower is mere probability. It takes much time and 

 attention to make sure of the results of such insect visita- 

 tions. Certainly the delicate green-white coloring of 

 one species and the magenta of the other directly indi- 

 cate the adaptation of the flowers to insect visitors. 



The immature berry of Streptopus is green-white and 

 distinctly triangulate three-lobed ; when ripe the ovoid 

 berry is a translucent cherry-red ; the slender stems are 

 abruptly bent near the middle.
