﻿144 Small : Studies in the Botany 



purplish : leaves numerous, opposite ; blades ovate or elliptic, 

 1.5-5 cm - l° n g' obtuse or acutish, serrate, densely punctate, sessile 

 or nearly so, the upper surface somewhat marked with impressed 

 nerves, the lower surface paler, marked with prominent lateral 

 nerves : racemes rather crowded at the end of the stem : calyx 

 campanulate, 2-5 mm. long, faintly ribbed, grandular punctate, 

 with both lips of the same size : corolla pale blue, 1— 1.3 cm. long, 

 contracted and curved at the base, glandular-punctate and glandu- 

 lar-pilose, delicately nerved ; lower lip suborbicular, notched at 

 the side ; upper lip much larger than the lower, nearly truncate 

 at the apex, with an ovate segment at each side : stamens slightly 

 surpassing the upper lip ; anthers strongly bearded. 



Collected by the writer along the Altamaha River swamp in 

 Liberty county, Georgia, June 18-21, 1895. 



Nearest Scutellaria pilosa, but more rigid in habit. The numer- 

 ous firm sessile or very short-petioled leaf-blades with their com- 

 paratively finely serrate margins form a strong contrast with the 

 sparse thin coarsely-crenate or crenate-serrate, long-petioled leaf- 

 blades of its most closely related species. The corolla too is much 

 smaller. In addition to these differences, the pubescence is much 

 shorter and is more dense. 



/ Vernonia flaccidifolia. 



Perennial, sparingly pubescent or glabrate. Stems erect, I— 1.5 

 meters tall, slender branched above : leaves rather numerous ; blades 

 thin, elliptic below to linear-lanceolate above, 0.8-2 dm. long, 

 acuminate, sharply serrate, sometimes doubly so, attenuate into 

 short petioles : corymbs 1-2 dm. broad ; branches slender : pedun- 

 cles barely enlarged at the top : involucres hemispheric, 3-4 mm. 

 high, light green : bracts ovate to oblong, obtuse, ciliate, some- 

 times colored at the tip, not at all spreading : pappus pale straw- 

 color : achenes 3 mm. long, with sharp ribs upwardly barbed. 



On wooded hillsides, Ringgold, Georgia. 



A species of rather delicate habit related to Vernonia ovalifolia 

 T. & G., but differing in its much less rigid habit, glabrate foliage 

 and larger differently shaped leaves which are of a very thin tex- 

 ture. The smaller involucres with their obtuse bracts and the pale 

 straw-colored pappus are diagnostic. 



The original specimens were collected by the writer on moun- 

 tain sides about Ringgold in northwestern Georgia in August 



1895.
