Thysanocarpus curvipes subsp. curvipes

The most widespread and variable subspecies of T. curvipes, distinguished from the other subspecies by: 1) having pubescent stems; 2) lacking the distinguishing character states (large, perforate fruits & long styles) of T. c. subsp. elegans and T. c. subsp. longistylus, respectively. The fruits, as can be seen in the photographs below, are quite variable; however, many of these variations can be found within a single population. For instance, one may occasionally see glabrous-fruited, imperforate-winged; glabrous-fruited, perforate-winged; pubescent-fruited, imperforate-winged; and pubescent-fruited, perforate-winged fruits all growing side by side within a single population.
