AK OECHID NOTE. 337 



An Orchid Note. 



Solomon Conrad's paper of 1839, on Corallorhiza Wisteriana, 

 falls short of being the original publication of that species ; for 

 Eaflnisqne a dozen years earlier had just made that plant the type 

 of a new genus under the name of Cladorhiza. He calls the spe- 

 cies" CI. maculaia,"m evident allusion to the notably spotted lip of 

 the flower. To this organ, the lip, he ascribes three essential char- 

 acters. It is "spotted, elliptic, obtuse, crenate," which I note as 

 a more perfect description of that organ than either Conrad or 

 any one else since Eafinesque's day, in so far as I have read 

 seems to have given. None but he mentions the crenulate char- 

 acter of it, though the figure in Britton & Brown clearly shows it. 



1 here present the fuller account, as to its history, of what I 

 should call 



CoEALLOEHizA MACULATA. Cladorhiza maculata, Eaf. Am. M* 

 Mag., i. 439 (1817). 



Corallorhiza Wisteriana, Conrad. Journ. Philad. Acad., vi, 145 

 (1839). 



As a frequent plant in woods on the outskirts of the Phila- 

 delphia of the early nineteenth century, it might be expected 

 that Eafinesque would have been the first to note its character, 

 for he was familiar with the Philadelphia region at the time. 



Certain Rosaceous Qenera. 



From the view of Potentilla, as a fair aggregate of many sub- 

 generic types — the view I took nineteen years since' — I have 

 long since receded. Mr. Eydberg has taken a middle ground, 

 which is logically untenable. But he has brought out several 

 new characters for each of several segregate genera, and this so 

 clearly that I must concede the untenability of my former 

 position. But neither can I conform to his scheme. If Horkelia 

 and Drymocallis, just alike in habit, are distinct, then is Trido- 

 phyllum, so peculiar in habit, flower and fruit, also an excellent 

 genus.'' If Argentina be separate from Potentilla it is by habit
