Corispermum pallidum Mosyakin[FNA4, HC2]
pale bugseed

Publication: Novon. 5: 347, fig. 1B. 1995.

Origin: Native

selected vouchers: WTU

Notes: Recently described from sand deposits in Douglas and Grant Cos. (Mosyakin 1995), last collected in 1931.

FNA4: "The combination of characteristics of Corispermum pallidum is very distinctive: pale, flattened, and small fruit body; very wide (especially as compared to the fruit dimensions), thin, translucent wing with erose margins, long style bases (ca. 0.7-1 mm, including their parts adnate to wing), distinctly divided in their upper parts to below the edge of the wing. Young bracts and distal leaves of C. pallidum are often papillose on margins and veins, in combination with typical branched trichomes. Corispermum pallidum seems to be related to the eastern Asian C. macrocarpum Bunge ex Maximowicz aggregate (subsect. Platyptera Mosyakin)."
