4. Balduina (Baldwinia) Nutt. This name is a homonym of 
Rafinesque’s Baldwinia, published a few months earlier in the 
American Monthly Magazine (2: 267. F. 1818). Elliot, retain- 
ing Nuttall’s name Balduina, proposed to separate one of the two 
species as a separate genus, under the name Actinospermum, and 
this name must now be applied to both species if they are to be 
retained in the same genus, as is done in the synonymy given be- 
low. If the two species are held as constituting distinct genera, 
as is done by Torrey and Gray, Darby and Chapman (even in the 
last edition of his Flora, recently published), the name Actino- 
spermum belongs to A. angustifolium, and the other species must 
receive a new generic appellation, in which case Exdorima Raf. 
seems to be eligible, with Balduina uniflora Nutt. as its type, 
though the name was not properly published by Rafinesque. 
. Mnesiteon Raf. (Fl. Ludov. 67. 1817) is given by the Kew Index 
as a synonym of Bal/dwinia Nutt., but it certainly:is more than 
doubtful if this is correct. The only apparent ground for this 
view is that Rafinesque notes a resemblance between the type of — 
his Mnesiteon and Buphthalmum angustifolium Pursh.
