Thysanocarpus curvipes Hook.[FNA7, HC, HC2]
sand fringepod, lacepod

Publication: Fl. Bor.-Amer. 1: 69, plate 18, fig. A. 1830.

Origin: Native

selected vouchers: WTU

Notes: FNA7: "Thysanocarpus curvipes is the most widespread and variable species in the genus. Variants have been named as varieties or species, but they grade into each other imperceptibly. Notable among these are var. elegans, a form with incised or perforate fruit wings, and var. eradiatus, a form with rayless, entire wings. Some of these may be the result of hybridization with other taxa. For instance, var. elegans has large fruits and occurs in the vicinity of T. radians, the largest-fruited member of the genus. Furthermore, fruits of var. elegans often have pointed hairs like those usually found on fruits of T. radians; such hairs are not found on fruits of any other members of the genus. Thysanocarpus curvipes includes both diploid and tetraploid populations (M. D. Windham, unpubl.), but these do not appear to segregate into recognizable groups. Although the variation in T. curvipes is considerable, its great complexity prevents recognition of infraspecific taxa at this time."
