minating in two long slender tubes. Berry globose, oblong or ovoid, half an inch in diameter, 

 bright scarlet, of an agreeable acid taste, persistent during part of the winter.

[ Named in honor of the distinguished French chemist Gay-Ldssac, whose analytical researches have rendered essential 



aid to Botany.] 



Calyx adherent to the ovary, 5-toothed. Corolla cylindrical, ovoid, subglobose or campanulate, 

 5-cleft or 5-toothed. Stamens 10 : anthers unawned ; the cells produced at the apex into 

 a tubular appendage. Ovary 10-celled, with a single suspended ovule from the summit of 

 each cell. Fruit a berry-like globose drupe, 10-celled ; the nucules separating at maturity. 

 Endocarp crustaceous. Embryo slender, cylindrical. — Shrubs with the habit Vaccinhjm. 

 Leaves often sprinkled with resinous dots. Flowers in lateral racemes, bracteate ; the 

 bracts sometimes leafy. Corolla purplish scarlet, greenish or white. Fruit dark blu& or 

 black. 



The Nortli American species of tliis genus have altogether the aspect of Vaccinium, but difler in the fruit, as 

 shown by Dr. Gray in the paper quoted above. It was proposed to constitute of them a separate genus under the 

 name of Decach^na (subsequently named Decameriom by Mr. Nuttal!) ; but we now refer them to Gaylussacia, 

 from which they do not differ essentially. In appearance and taste the fruit resembles that of the common Vacciniums, 

 but is not so much esteemed on account of the large crustaceous nucules.

A shrub about one foot high, with a long creeping root or rhizonia, somewhat naked below, 

 branching above ; the younger branches pubescent, and more or less glandular. Leaves 

 1-2 inches long, deciduous, rather thick when old, veiny. Racemes 2-3 inches long ; the 

 flowers few and distant ; bracts resembling the leaves, but smaller. Calyx glandular ; the 

 segments triangular, acute. Corolla large, white, 5-angled, smooth ; the segments short and 

 a little recurved. Stamens shorter than the corolla : filaments pubescent : anthers with long 

 tubular appendages. Style long and slender. Fruit black and shining when ripe, glandularly 

 pubescent, watery and rather iiisipid. 



Borders of ponds, and in wet sandy soils. Fl. June. Fr. August.
