“…Previously, the chromosome number 2 n = 20 was reported by Cardona (1977) from a population located near our sampled accessions from Cosconar. Both x = 10 and x = 11 numbers have been reported in Pimpinella species [see Abebe (1992) for a general discussion of the cytogenetic features of the genus]. Abebe (1992) reported conflicting results concerning n = 10 and n = 11 in some tropical African species, and suggested that misidentifications or technical inaccuracies were responsible for the disagreements.…”

However, it should be stressed that intraspecific aneuploid variation has been demonstrated in at least 14 species, including P. affinis Ledeb.…”

We have revised the voucher specimen (BC) used by Cardona (1977) and agree with her determination.…”

Mitotic chromosome numbers are reported from 35 vascular plant taxa endemic to the Balearic Islands that are poorly known cytogenetically. The chromosome numbers of Chaenorhinum rodriguezii (2 n = 14), Coristospermum huteri (2 n = 22), Carduus ibicensis (2 n = 26), Filago petro-ianii (2 n = 26), Ononis crispa ssp. zschackei (2 n = 30), and Ophrys bertolonii ssp. balearica (2 n = 36) were determined for the first time. New chromosome numbers are reported in Pimpinella bicknellii (2 n = 22), Calamintha rouyana (2 n = 46), Vicia bifoliolata (2 n = 14), and Teucrium asiaticum (2 n = 30). A new diploid cytotype (2 n = 16) was found in Ranunculus paludosus ssp. barceloi , which is restricted to populations from the western Balearics (Eivissa and Formentera), whereas tetraploid plants are known from the eastern Balearics (Mallorca). It is suggested that the tetraploid cytotype arose from the diploid cytotype through autopolyploidy. The idiograms of Coristospermum huteri , Pastinaca lucida , Pimpinella bicknellii , Carduus ibicensis , Helianthemum scopulicolum , Helichrysum crassifolium , Vicia bifoliolata , P aeonia cambessedesii , Helleborus lividus , Ranunculus paludosus ssp. barceloi , and Linaria aeruginea ssp. pruinosa are determined for the first time.

“…The c. 150 species constituting the genus Pimpinella L.-Apiaceae Lindl.-are distributed in temperate and subtropical regions of Eurasia and Africa including Madagascar. Turkey is one of the main centers of diversity for this genus along with Africa and Madagascar (Aksenov 1972;Abebe 1992). In his classical monograph, Wolff (1927) subdivided Pimpinella into three sections-P. sect.…”

To explore if fruit morphology could aid in taxonomy of the genus Pimpinella L., we have undertaken a study of fruits from 26 Turkish taxa of Pimpinella using light and scanning electron microscopy—SEM—. A great deal of inter and intraspecific variation for both fruit shape and surface was observed. Fruit shapes of Turkish taxa of Pimpinella range from oblong-cylindrical to subglobose and indumentum when present can be strigose, hispid and may include hamate trichomes. Variation in fruit surface is also considerable and allows recognizing nine different ornamentation patterns. However, variation in shape, surface ornamentation and indumentum is not tightly associated since species with similar fruit shapes do not necessarily have similar surface ornamentation. To jointly analyse fruit morphology together with the most commonly used morphological characters of the whole plant and to compare morphological evidence with available phylogenetic hypotheses, a cluster analysis was also performed: the Turkish species of Pimpinella were clustered into two distinct groups, the second one subdivided in another two subgroups.

“…The genus Pimpinella L. (Apiaceae) includes about 150-170 species and is disjunct between Africa, Asia, and Europe (Pimenov and Leonov, 1993;Pu and Watson, 2005). It is one of the largest genera in Apiaceae and considered as taxonomically complex genus due to its wide geographical range and diverse morphological variation (Abebe, 1992). Small and rather featureless fruits are the general characteristics of this genus (Pu and Watson, 2005).…”

Pimpinella saxifraga L. (Scarlet pimpernel or Burnet saxifrage), a newly introduced species, was found from Baekyakyi oreum (a parasitic cone or cinder cone) in Seogwipo, Jejudo Island. This species is native to Europe and western Asia and is reported as a widely invasive species around the world. Pimpinella saxifraga is distinguished from other related Korean taxa by leaves that are pinnately compound with 3?7 pairs of segments, which vary from simple, ovate, to 2-pinnatisect, with linear lobes. The vernacular name of "Baek-yak-yi-cham-na-mul" was assigned after the name of the cinder cone where it was initially discovered. We provide descriptions of the morphological characters, photographs and a key to allied taxa in Korea. The geographical origin and introduction routes are unknown, but it is highly likely that it was introduced as fodder given its high nutritious value for sheep and cattle or as a medicinal herb. This species invades commonly grasslands and woodlands and prefers dry, well-drained, and calcareous soils. The distribution of this species was analyzed by searching extensively in surrounding Baekyakyi oreum and adjacent cinder cones, but no other populations were observed. It is protected commonly at the edges or inside of the patchy pine forest in the cinder cone from grazing by cattle; given the worldwide invasive nature of this species, special monitoring and management plans should be developed.
