GRANT—A MONOGRAPH OF THE GENUS MIMULUS 211 
long, .5-2 em. broad, obtuse, dentate or erose, 3-5-nerved from 
the base, upper leaves sessile by а broad clasping base, the lower 
sessile or short-petioled; pedicels slender, elongated, 2-4 times 
the length of the leaves; calyx campanulate, 7-8 mm. long, tinged 
with red, sometimes minutely puberulent, much inflated and oval 
in fruit, the top appearing as though truncate, teeth broadly 
triangular-acute, 1 mm. long, nearly equal, the orifice scarcely 
oblique; eorolla 1.5-2.2 em. long, broadly funnelform, the lower 
lip and open throat spotted with red, lobes unequal, little spread- 
ing; style glabrous, stigma-lips oblong, nearly equal; capsule 
included, elliptical, acute, short-stipitate, placentae separating 
at the apex; seeds smooth, oval, less than twice as long as broad, 
not apiculate. 
Distribution: in wet places from central to southern Chile. 
Specimens examined: 
Chile: Colchagua, 1862, Bridges or Cuming ? (U. S.); Cauquenes, 
without date, Reid (G); stagnant ditch, Valdivia, 12 Nov., 
n Buchtien 109 (Calif.); without further data, Dr. Styles 
Phil.). 
Clos has described two varieties: (1) stolonifera, tall plants with 
remote leaves, either short or long-petioled, acute and erose- 
dentate; (2) integrifolia, small plants, leaves close together, sessile, 
Subconnate, nearly entire. Material of these varieties has not 
been seen by the writer. M. longipes Ph. in Linnaea 29: 28. 
1857-58, is probably a synonym of the variety integrifolia.

Stems slender, 5-15 cm. high, glandular-puberulent, simple or

mm. broad, acute, base cuneate or acute, entire or irregularly 
denticulate, puberulent; pedicels filiform, shorter than the corolla,
