name is more than once revertible ; for Rafinesque had a 

 Purshia in print as early as 1813. I find no record of any 

 earlier Kunzia than this of Sprengel, which mo8t writers wlio 

 liave mentioned it say was substituted for the Candolleau 

 Purshia in Sprengel's Systema, 1825 ; but I find it four years 

 earlier than that, in the first edition of Steudel's Nomenclator 

 (1821). The known species are two, and their names will 



stand as follows.

 d'Oreille in northern Idaho, where the wild red cherry, 

 Cerasus mollis, Dougl. is common, I found a thrifty young 

 tree of this species well laden with ripe fruit, upon the boughs 

 of which I noted many instances of a double drupe, or rather 

 of two distinct drupes produced from a siugle flower. In 

 other words, many of the flowers of this tree must have been 

 furnished with two distinct pistils, each of which attamed 



maturity, TV
