Discussion
Scapiform to subscapiform plants of Marshallia caespitosa with relatively few cauline leaves and heads borne singly occur mostly in Oklahoma and southeast Texas and Louisiana. Plants with more or less leafy stems and one to relatively many heads are sometimes recognized as var. signata; they grow mostly in central Texas.
