than the pedicels, the outer often of the same length, sometimes a half 

 longer, both hyaline-margined and attenuate-acute; flowers 2 to 5 on 

 slender, erect pedicels; perianth dark blue with a yellow eye, its seg- 

 ments 12 to 15 mm long; stamineal column 5 to 6 mm long: ovaries 

 glandular-puberulent; capsules globose, 4 to 5 mm broad; seeds black, 

 foveolate, 1 mm long, the angles irregularly winged. 



Collected in swamps near Vancouver, June 5, 1905, no. 4926, the 

 type in the National Herbarium. The species is closely allied to S. ida- 

 hoense Bicknell, but its frequently branched stems scarcely permit its 

 association therewith. Typical S. idahoense occurred, however, in drier 

 ground near by and it is possible that our plant is merely a luxuriant 

 branched form of that species.
