New Species of the Genus Mimulus. 



M. MiNTHODES. Akin to M. ringens, but stem wing-angled 

 much as in M. alatus, also the leaves lanceolate, narrowed at 

 both ends and short-petioled, the petiole winged, the margins 

 of all leaves lightly crenate-serrate : peduncles long, surpass- 

 ing the foliage : calyx-teeth subulate, aristate-acuminate. 



Rare or local in the southern United States, where M. 

 ringens is also widely dispersed ; differing from that by its 

 wing-angled stem and exactly lanceolate foliage, while from 

 M. alatus it is distinguished by its long peduncles and subu- 

 late calyx-teeth. The type specimens are in U. S. Herb, and 

 were collected at Birmingham, Ala. , Aug. , 1888. Others quite 

 like them, but younger, were gathered at Rome, Georgia, in 

 the same year. 



M. ACUTANGUI.US. Allied to M. ringens, and with similarly 

 spatulate-lanceolate or oblong-lanceolate foliage lightly ap- 

 pressed serrate, but stem sharply angled, the fruiting calyx 

 very short and thick, its teeth short, abruptly aristate-pointed 

 above a deltoid base, also erect, not converging over the cap- 

 sule like those of M. ringens. 



A northwestern type which, despite its short erect calyx- 

 teeth and somewhat angular stem, has no marked character in 

 common with M. alatus. The type specimens in U. S. Herb, 

 are from Crow Wing County, in central Minnesota, J. H. 

 Sandberg, 19 Aug. 1891. M. ringens itself appears to be 

 common in Minnesota. 



I next subjoin a few segregates of the group of which M. 

 cardinalis is typical. Indeed, all the forms here brought to 

 notice have been carelessly labelled and distributed for that
