 more or less pubescent ; raceme sessile or short- 

 peduncled, 2-5 cm. long; mostly 5-8-flowered, 

 rachis often zigzag; pedicels slender, the lower 

 10-15 mm. long, spreading; perianth-segments 

 4-7 mm. long, lanceolate, rarely 3-nerved ; 

 stamens half to two-thirds as long as segments ; 

 style about equalling the ovary; berry globose, 

 6-10 mm. in diameter, dark-purple ; seeds 1-3, 

 3 mm. broad, brown. 



On moist slopes and stream banks. Transition Zone; 

 British Columbia to Montana and Utah, south through 

 western Oregon and the Coast Ranges of California to 

 Monterey County.

 at least the lower, often 2 or 3 times as long as 

 the flowers ; perianth-segments oblong, obtuse, 5-7 

 mm. long; stamens half as long; style 1 mm. long; 

 berry reddish purple, 7-10 mm. in diameter. 



Wooded slopes. Arid Transition and Canadian Zones; 

 British Columbia to New Mexico and southern California. 

 Closely related to the eastern V. stellata (L.) Morong, to 

 wliich it has been referred. Type locality: "the higher 

 .Sierra in California." 



6. UNIFOLIUM Haller; Zinn, Cat. Plant llort. Goett. 104. 1757. 

 [Maianthemum. Wigg. Prim. Fl. Hols. 14. 1780.] 

 Glabrous or pubescent herbs, with slender rootstocks and simple erect few-leaved stems. 

 Leaves alternate, solitary, petioled or sessile, cordate. Flowers small, white, in a terminal 

 raceme, the pedicels often 2 or 3 together. Perianth of 4 separate spreading segments. 

 Stamens 4. inserted at the bases of the perianth-segments, filaments filiform ; anthers 

 introrse. Ovary 2-celled, sessile, globose; ovules 2 in each cavity; style slender, 2-lobed or 

 2-cleft. Berry globose, 1-2-seeded. [Many plants bear only a solitary long-petioled leaf, 

 arising from the rootstock, whence the Latin name.]
