I am unable to quote definitely any more than the four 

 different applications of this name hinted at above. But a 

 fifth use of Nidtallia I find a trace of in SprengePs Systema, 

 who credits it to Nees Yon Esenbeck, as having been founded 

 on a species of Trigonia, Aubl. The date of this homonym 

 must be 1826 or earlier. 



De Candolle's Nidtallia^ which Rafinesque's Nemopanthes 

 antedates by four years, is monotypical, well known, and 

 therefore not liable to rise up against the NuUallia which 

 has been everywhere in recent years accepted. 



The case of the fine raalvaceous NuUallia of Barton is 

 somewhat complicated. During ten or twelve years immedi- 

 ately succeeding its publication, it seems to have met with 

 acceptance everywhere. Various species, under this name, 

 ^ere described and beautifully figured in such popular 

 serial publications as Sweet's British Flower Garden, the 

 Botanical Magazine, the Botanical Register, and Paxton's 

 Magazine. In 1834 :Nuttall, confident of the stability of the 

 genus and of the permanency of the connection of his own 

 name with it, transferred thereto the Malva Munroana of 

 Douglas and added the name and specific character of a new 

 Nattallia cordifolia} Not long after this Sir William 

 Hooker, without actually deposing the genus, suggested 

 that the species might perhaps be distributable between 

 Malva and Sidaf and in 1838 Asa Gray, then young, with 

 little experience, and with aggressiveness according to his 

 years, reduced all the species to 3falva/ not failing to create, 

 in tlie RfliYiA volnmA a new NutkilUa of his own. But his
