OF ARTS AND SCIENCES. 35 



Korthals should have the credit of rightly making out the character 

 of the singular plug which occupies the summit of the pyrena3 of the 

 fruit in these plants ; but he apparently was not aware that A. Richard 

 had remarked the same thing in Gmttarda, and rightly understood it. 

 It is, in fact, a general Guettardosous character, as also is the exalbu- 

 minous seed, now first made known. 



The amended characters, and the synonymy of the two genera in 

 question, are subjoined, with the diagnoses of some new species.
