climate. The flowers, also, are mostly larger and solitary, on peduncles 
which are often six or nine lines long. From JS. ¢enella the New- 
foundland plant differs in its alternate leaf scales, loose few-flowered 
raceme, and relatively larger corolla, which in the fresh state is pinkish; 
also in its purplish anthers. More perfect material of the United 
States form of Centaurella Moseri is much to be desired.” 
The combination, Bartonia Mosert Rob. & Schrenk, was later pub- 
lished in Britton & Brown’s Ill. Fl. 2:621, where it is used to cover 
both the United States material and the Newfoundland plant. Having 
just received additional specimens of the latter, collected at Grand 
Lake, Newfoundland, by the Rev. A, C. Waghorne, and in all regards 
identical with those from Holyrood, the writer has made further study 
of the plants in question, and is now forced to the conclusion that the 
Newfoundland form is distinct from any species of the United States. 
{t may be characterized as follows : 
Bartonia iodandra, n. sp.— Delicate annual, 4 to 12™ high; root a 
fascicle of few slender fibers; stem single, erect from a somewhat bent 
or decumbent base, either quite simple and terminated by a solitary 
flower, or alternately branched above the middle; branches 0.5 to 3™ 
long, erect or curved-ascending, being mostly simple leafless peduncles 
each bearing a solitary terminal flower, but the lowest rarely bearing 2 
or 3 flowers; leaf scales alternate, subulate, 2 to 3™" long; flowers at 
full maturity 6 or 7™" long, distinctly purplish-tinged ; calyx turbinate 
below, its segments ovate-oblong to oblong-lanceolate acuminate ; 
corolla about twice the length of the calyx, when fresh of flesh color, 
in dried state becoming slightly yellowish but retaining even after 
Several years a suggestion of its erubescent coloration, its segments 
rather broadly oblong, obtusish and mucronate; anthers at maturity 
deep purple or dark maroon; filaments broadened below; ovary ovoid, 
obtuse, surmounted by a thickish sessile short-columnar slightly 
bilobed stigma which is included within the corolla—Bartonia sp.
