LOBELIA FLACEIDIEOLIA.
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 wirelike; 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 [.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 plant in the narrower calyx-segments and narrower segments of the lips of the corolla.
The original specimens were collected by the writer in the Ochlockonee River swamp, near Thomasville, Georgia, July 12 22 13c95.
