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.
"broader" is not a number.
