conic-ovoid; sepals lanceolate, acuminate, the tips very slightly 
spreading; achenes suborbicular, 6-8 mm. in diameter, puberu- 
lent, abruptly narrowed at both ends, with an orbicular impression 
in the middle, sometimes slightly inequilateral, the plumose style 
erect or slightly oblique, 5-6 cm. long, tawny, lustrous, the hairs 
spreading. 
Collected by the writer in the Yellow River valley, near Mc- 
Guire’s Mill, Gwinnett county, Georgia. In flower July 2, 1895, 
in fruit July 11, 1893. 
A handsome species between Clematis Addisonii and C. Viorna, 
_with foliage somewhat resembling that of the former and with the 
habit of the latter. It differs from C. Addtsoni in its much elon- 
gated and climbing stem, and the distinctly petioled and acute 
floral leaves. It may readily be distinguished from C. Viorna by 
its suborbicular achene and longer plumose styles, as well as 
by the foliage. 
/ LOBELIA FLACCIDIFOLIA. 
Perennial, slender, deep green, glabrous or nearly so. Stems 
erect, 2-6 dm. tall, solitary, or loosely tufted, usually branched 
above, or, in small plants, rarely simple, the branches wire-like ; 
leaves thin, the basal or lower cauline obovate or oblong-spatu- 
late, the rest linear-oblong or rarely linear-lanceolate, 3-10 cm. 
long, obtuse, undulate or crenate-undulate, short-petioled; racemes 
interrupted, .5-2 dm. long, recurved; pedicels erect, slightly 
curved, 4-5 mm. long, usually exceeded by their bracts; calyx 
glabrous, its tube broadly turbinate, becoming globose-hemi- 
spheric and strongly ribbed, its segments linear-lanceolate, 4-5 mm. 
long, acute, spiny-toothed, auricled at the base, slightly revolute ; 
corolla about 1.5 cm. long, blue, sparingly pubescent without, the 
segments of the upper lip reflexed, crisped, about % as long as 
the tube, the lower lip as long as the tube, its segments acute, the 
middle one lanceolate, the lateral ones oblong-lanceolate ; staminal 
tube ascending, anthers pubescent; capsule ovoid, 5-8 mm. long, 
beaked, the free portion somewhat shorter than the part adnate 
to the calyx-tube. 
In sand in deep river swamps, southern Georgia. Summer. 
The species here described as new is, on the whole, most 
closely related to Lobelia Ludoviciana, from which it differs in the 
delicate habit, the very thin texture of the leaves and the branch- 
ing stems; there are characters in the flower to separate it from 
- the Louisiana piant in the narrower calyx-segments and narrower 
segments of the lips of the corolla.
