Plant glabrous, glaucous or pale green; stems 6 — 20 inches high, 
slender, with 1 — 3 leaves below the fork; leaves ovate-lanceolate, oblong, 
or oval, margin smooth, apex acute, base rounded or narrowed; flowers 
pale yellow, 10. — 15 lines long; perianth-segments glandulose papillose 
within; stamens shorter or equaling the styles, connective, acute; cap- 
sule obovoid, truncate, 4 — 5 lines long, thicker, obtusely 3-angled, the 
sides concave and the angles grooved, the lobes dehiscent above. The 
type locality is: ''Habitat in Virginia, Canada. ’’ 
This plant occurs in moist woods. The range as given by Britton and 
Brown is “Quebec and Ontario to Florida and Mississippi”. Conway 
’MacMillan in “Metaspermae of the Minnesota Valley” gives the v/estern 
range as Minnesota^ Dakota and Missouri. Iowa is thus within the range 
and the species should occur. Occasionally it has been reported, but all 
reputed specimens so far examined have proven to be the preceding 
species.
