GRANT—A MONOGRAPH OF THE GENUS MIMULUS 131 
Nebraska: Lincoln, Aug., 1888, Webber (M); Red Bird Creek, 
26 July, 1893, Clements 2786 (Cornell). 
Minnesota: Minnetonka, Oct., 1886, Davidson (Pomona); Nicol- 
let, July, 1892, Ballard (В. Mt.); Portage, 18 July, 1891, 
Woods (R. Mt.). 
M. ringens is one of the common species in the genus and can 
be distinguished by its blue personate corolla, its long pedicels, 
and its usually sessile leaves. 
la. Var. minthodes (Greene) Grant, comb. nov. 
M. minthodes Greene, Leafl. Bot. Obs. & Crit. 2: 1. 1909. 
Leaves elliptical, acute at each end and often short-petioled. 
Distribution: southeastern United States. 
‚ Specimens examined: 
Georgia: wet meadow, Lafayette, 925 ft. alt., 2 Aug., 1900, 
Harper 342 (N. Y.). 
Maryland: Front Pike, College Park, 3 Oct., 1900, Pond (M). 
The variety merges into the species through such specimens as 
Beymour 25 from Massachusetts, Shull 108 from Maryland, and 
Blanchard's specimen from Washington, D. C. In this last 
specimen some of the leaves are short-petioled or sessile by а 
narrow base and the others are broad and auriculate-clasping. 
Boettcher 245 from Washington, D. C., has both clasping and 
short-petioled leaves on the same plant and the upper part of 
estem is winged. Overacker’s specimens from Syracuse, №. Y., 
and Lake’s specimens from the Michigan Agricultural College 
show winged stems also. As is usual with blue-flowered plants, 
occasional plants are found with white or pale pink corollas. 
Examples of these are to be found in the following specimens 
collected in New York: Ithaca, 20 July, 1878, Dudley (Cornell); 
damp soil along Glenwood Road, Ithaca, 19 Aug., 1913, E. L. 
Palmer 1089 (Cornell); West Marsh, Ithaca, 19 Aug., 1913, 
E. L. Palmer 1084, (Cornell).
