DIOECIA. TETRANDRIA. 233 



calix6 to 8 imbricatrd scales wlih tomentose margins; an- 

 thers purplish. Calix of the fruit similar to tb.at of the 

 stamens; style distinct, rigid and persistent, stit^mas 

 about 4 or 6, purple, 2 only conspicuous; berry yellow- 

 ish, small and astringent to'the taste, 2-seeded, seeds bo- 

 ny, plano-convex, v. v. Near Augusta in Georgia, on 

 gravelly hills. 



This genus witli Empetrnm ought apparently to form a 

 section (F.MPETRE;E)at theend ofthe CoxiFERiE, charac- 

 terized by producing a berry containing more than 1 nu- 

 clform se"^ed. The affinity o'f Ceratiola to Taxiis, though 

 certainly remote, still appears to justify the reference of 

 these t\vo genera to this family, with which they also 

 agree in the structure ofthe seed, rather than the Eric-e 

 which they resemble in nothing but the leaves!

Species. 1. E. nigrum. Berries nearly black. Hab. 

 In Canada. 



Of this genus there are 2 species in Europe, E. album 

 in Portugal and E. nigrum in ihe northern parts of Eu- 

 rope, there is also a third species indigenous to the 

 Straits of Magellan, and probably a fourth in Guianne, 

 which I have observed in the herbarium of A. B. Lambert, 

 Esqr., London.

t Dedicated to William Maclure, Esq. of the United States, 

 a Philosopher, whose devotion to natural science, and particu- 

 larly to the geology of North America, has scarcely been ex- 

 ceeded by RaiBond or Saussure in Europe.
