style slender, two-thirds as long as the petals; stigmas filiform, 3-4 
mm. long; capsule at length subglobose, or globose-obovoid, 6-7 
mm. long, on a stalk which exceeds the body, the angles strongly 
winged, the faces strongly ridged; seeds very irregular, minutely 
papillose, black, 1 mm. long. 
North Carolina and Georgia. 
Most closely related to K. Al/eniand part of Torrey and Gray’s 
var. 8. It differs especially in its erect habit, very different basal 
leaves and larger flowers. 
4. KNEIFFIA LONGIPEDICELLATA n. sp. 
Annual, slender, bright green, more or less puberulent, stem 
erect or assurgent, 4-7 dm. tall, red, slender, simple or sparingly 
branched above; basal-leaves spatulate or obovate-spatulate, 4-6 
cm. long; stem-leaves few, linear-lanceolate, 3-9 cm. long, obtuse 
or acutish, entire, often somewhat undulate, narrowed into a short 
petiole ; flowers yellow, subtended by leaf-like bracts in terminal 
racemes which are sometimes corymbosely arranged; calyx hir- — 
sute, its tube slender, 1-1.5 cm. long, its segments linear, longer 
than the tube, the tips free in the bud; petals obovate, 2 cm. long, 
many-nerved, emarginate, stamens less than one half as long as the 
petals ; styles slender, two-thirds as long as the petals; capsule nar- 
rowly obovoid, 1 cm. long, its angles winged, its faces ridged, on 
pedicels longer than the body; seeds irregularly oblong, .8 mm. 
long, brown, minutely papillose. 
West Virginia to North Carolina and Florida. 
Between K. subglobosa and K. linearis. It differs from the 
former in its sparsely leafy, usually nearly simple stem, the hirsute 
calyx, the larger flowers and the narrowly obovoid capsules. It 
can easily be separated from K. linearis by its pedicel, which ex- 
ceeds the body of the capsule.
