Similar Species
There are several look-alikes within the range of Yabea microcarpa in B.C. Torilis japonica, an introduced Japanese plant, is distinguished from Y. microcarpa by a single bractlet that subtends the flower. Torilis japonica has beaked fruits; Y. microcarpa has beakless fruits. The fruit of T. japonica is covered in generally distributed prickles rather than along the ridges as found in Y. microcarpa. Similarly, Anthriscus caucalis, from Europe, differs by having beaked fruits with a ring of short flattened hairs on each seed rather than along the ribs. Daucus pusillus has similar foliage as Y. microcarpa but does not have flowering stems exerted beyond the subtending bracts (Douglas and Smith 2004e).
