standing the Wrightla of Brown, by an allowable and fairly euphonious 

 combination of baptismal and surname, I am able to dedicate this genus 

 to Mr. Charles Wright.^ the first discoverer of one of the species, my 

 esteemed associate in botanical pursuits for more than thirty years, and 

 one of the most indefatigable of explorers. Although he has made 

 important and well-known collections in various parts of the world, 

 especially in Japan, and above all in Cuba, and although a large num- 

 ber of species bear his name as their discoverer, it is still most proper 

 that, in the generic form, it should be connected with the flora of North 

 America, with the region in which his botanical investigations began, 

 and which he most assiduously and largely explored.

In memory of Dr. Hezekiah Gates, who almost fifty years ago made 

 and distributed a considerable collection of Alabama plants, mostly from 

 the vicinity of Mobile. Among them was Petalostenion corgmhosus, 

 upon which the late Professor Bertoloni of Bologna (mistaking it for a 

 Composita !) founded his genus Gatesia. The present genus, I trust, is 

 better founded, and will keep up the name in connection with an Ala- 

 bamian plant.
