70 Rhodora [April 



but which has the stem forking, the leaves glaucous and soft-ciliate, 

 and the pedicels and flowers much longer than in S. hrevipcs ; and in 

 the alpine regions of the Shickshock Mountains of eastern Quebec 

 there is another plant with a simple or subsimple stem suggesting S. 

 hrevi'pes, but with short thick caudex and ciliate leaves much as in 

 S. roseus, and purplish flowers structurally like those of S. amplexi- 

 joUiis. These two plants, that of northern Michigan with slender 

 rootstocks, and the Shickshock plant with usually simple stems, ciliate 

 leaves and strongly recurved perianth segments, are apparently species 

 which have heretofore been unrecognized in our flora. In order to 

 make clearer the affinities of these plants, the characters of the other 

 eastern species of Streptopus are briefly included in the following 

 synopsis. 



* Rootstock short and thick. ' 



-t- Perianth-segments wide-spreading or recurved from near the middle: 

 anthers lance-subulate, entire, many times exceeding the filaments: 

 stigma subentire or merely lobed. |, 



Streptopus amplexifolius (L.) DC. Stem forking, very rarely 

 simple, 3-9 dm. high, whitish-green and glabrotis except occasionally 

 at base: leaves amplexicaul, glabrous throughout, glaucous beneath: 

 peduncles glabrous, simple or forked, in anthesis 1.5-3 cm., in fruit 

 1.5-8 cm. long: perianth greenish-white or sometimes roseate, its lance- 

 attenuate segments 8-11 mm. long: fruit globose to ellipsoid, 1-2 cm. 

 long, scarlet.— Fl. Fr. iii. 174 (1805). S. distortus Michx. Fl. i. 200 

 (1803). S. amplcxicanlis Poir. Diet. vii. 467 (1806). S. amplexi-

 from Labrador to Alaska, south to the mountains of North Carolina, 

 Michigan, South Dakota, New Mexico, and northern California; in 

 eastern Quebec ascending to subalpine regions: Greenland, Europe, 

 and Asia.
