oblong, strongly cuspidate capsule, about 1 inch long and half as 
wide ; the other form has a shorter ovary, 5-7. lines long, smaller I 
flower (perigon 7-8, tube i-i line long), and rather shorter an¬ 
thers, Capsule shorter, 8 lines long and 6 wide, with a short 
abrupt point. Both forms seem to ocur in all the localities men¬ 
tioned, and certainly belong together. I have been particular, in 
^describing them, because we rarely have" occasion to study 
numerous apd varying specimens of these plants, but must be 
generally satisfied with poor fragments, so that it is difficult to ? 
ascertain the amount of variation within the species.
