GRANT—A MONOGRAPH OF THE GENUS MIMULUS 101 
and by an illustration in ‘Hortus Upsaliensis," the diagnosis in 
each case being based on material collected in Virginia. In the 
first edition of Linnaeus’ ‘Species Plantarum," published in 
1758, M. ringens is the only species mentioned, making it, without 
doubt, the type species of the genus. A full description of 
Mimulus was given in the ‘Genera Plantarum,” which appeared 
a year later. Іп the second edition of the ‘Species Plantarum,’ 
published in 1763, the description of M. luteus was added, this 
being founded on material collected in Chile by Feuillee® in 1710. 
Within a few years, M. aurantiacus,* M. glutinosus,’ and M. alatus! 
were described, so that in Willdenow's ‘Species Plantarum,'? 
published in 1800, four species were recognized, and one, M. 
aurantiacus, was given as а synonym of M. glutinosus. In 1810, 
Robert Brown!* published the description of a new genus which 
he called Uvedalia and to this he referred a single species, U. line- 
aris, а native of Australia. This generic name, however, was 
soon reduced to synonymy. Several new species of Mimulus 
were subsequently recorded from time to time, but the first com- 
prehensive treatment of the genus was made by Bentham" in his 
paper on the Scrophulariaceae of India. Twenty-five species 
were recognized, ten of which were described for the first time. 
The first segregate of Mimulus was made by Nuttall’? when he 
published the genus Diplacus, basing his segregation mostly on 
the shrubby habit and on the separation of the placentae. Four 
species were described as new and M. glutinosus Wendl. was 
transferred to the new genus. 
Spach," in 1840, proposed the second segregate, Erythranthe,
