O. claytonii is easily confused with O. longistylis. The easiest way to tell them apart is to count the number of individual flowers in each umbellet; the former usually has 8 or fewer flowers, while the latter has at least 8 and up to 18. Also, as the specific epithet suggests, the styles of the latter are much longer (around 4mm) than the styles of the former (less than 2mm).
