corolla 4-11 mm. long; capsule narrowly ovoid, about 4 mm. long; 
pointed, tipped by the persistent style; seeds oblong, slightly 
curved, .3-.4 mm. long, yellowish-brown, transversely wrinkled, 
with usually rounded ends. 
Wet places, Ontario to Wisconsin and Missouri, south to the 
Gulf of Mexico. March to October. Ascends to about 670 
meters in the mountains of Virginia. 
_ My attention was first called to this plant by Mr. Bush's Mis- 
souri specimens (described as J. gratioloides curtipedicellata) and by 
some I collected in North Carolina. On taking up the subject I 
found no lack of material, there being twenty-two specimens in 
the Herbarium of Columbia University variously associated with 
twenty-five specimens of /. gvatiolordes, some even over the same 
label. J. attenuata can bé distinguished from J. gratioloides at 
sight by its stouter and lax habit and short pedicels, while a closer 
examination will show the calyx-segments of the former as long 
as or longer than the capsule, whereas those of the latter are. 
always much shorter than the capsule.
