Taeniopetalum Vis. (Apiaceae), a neglected segregate of Peucedanum L., supported as a
remarkable genus by morphological and molecular data
Tatiana A. Ostroumova, Michael G. Pimenov, Galina V. Degtjareva and Tahir H.
The genus Taeniopetalum Vis., comprising three species and two subspecies, has been
traditionally treated within Peucedanum L., sometimes segregated as a section or subgenus.
Molecular (ITS nrDNA sequences), morphological and especially microcarpological data
show that Taeniopetalum is distant from the type group of Peucedanum (P. officinale L. and
its allies). According to molecular data, P. obtusifolium Sm. belongs to the same clade. This
affinity is supported morphologically (by similarities in fruit structure). Thus P. obtusifolium
can also be placed with Taeniopetalum. A taxonomic treatment for the genus Taeniopetalum
is provided along with an identification key. Three new combinations are published:
Taeniopetalum arenarium subsp. borysthenicum (Klokov ex Schischk.) Pimenov & Ostr., T.
arenarium subsp. neumayeri (Vis.) Pimenov & Ostr. and T. obtusifolium (Sm.) Pimenov.
