Endemic
Basionym: Mimulus bigelovii var. cuspidatus A. L. Grant Ann. Missouri Bot. Gard. 11: 279. 1925
Synonyms: M. bigelovii var. panamintensis Munz M. spissus A. L. Grant
Treatment appears in FNA Volume 17. Treatment on page 435. Mentioned on page 436.

Stem internodes usually subequal. Leaf-blades: proximals obovate to oblanceolate, distals usually relatively broader, apices of proximals abruptly acute-acuminate, distals abruptly acuminate, sometimes cuspidate.


Phenology: Flowering Feb–Jun(–Sep).
Habitat: Washes, dry hillsides, limestone outcrops, scree slopes, periphery of trees and shrubs.
Elevation: (10–)100–2300(–3300) m.

Distribution

Ariz., Calif., Nev., Utah.

Discussion

Leaves of var. cuspidatus sometimes are more congested near stem tips under conditions of severe drought stress. Seeds from plants identified as Mimulus spissus, with leaves and flowers densely crowded at least distally, were greenhouse grown by D. M. Thompson (2005), who found that they produced plants identical to var. cuspidatus.
