Discussion and Conclusion
Due to the presence of a yellow tap root, sheathed leaf base, calyx
reduced, petals sparsely pubescent, anthers hairy at base, stigmas
linear, fruits intermixed with simple and T-shaped hair, the new taxon
is classified as belonging to the genus Koulium section Pimpinelleae of
the Apiaceae family. Membranous, scabrous, and with ciliate edges,
bracts and bracteoles. Stipules are missing, and the bases of the
petioles are narrowly sheathed. Reduced and joined to the ovary wall are
the calyx. White or pinkish-purple petals. The form seems obcordate and
emergent. The fruits are compressed dorsally. Furrows in the percarp
typically include vittae. Fruits have hairy primary and secondary ridges
are obscure. Carpels have a subpentagonal cross section, bifid
carpophores, and modestly constrained commissures. On the simple,
T-shaped fruits of this species, which also have wider bases, we
discover hair admixture. The fruit hairs of Aphanopleura andPsammogeton have a T shape. The shape of the fruit being
oblong-cylendric becoming gradually narrow towards base which are to
some extent similar to Pimpinella species, however, it differs
from them in sparsely hairy petals on outside and on margins and annual
in habit.
