“…However, the pollen studies did provide distinctive characters for some taxonomically difficult species, since Lomelosia palestina, Lomelosia prolifera and Lomelosia olivieri were previously placed in the genus Scabiosa based on the calyx which usually has five scabrous awns (TÄCKHOLM 1974;RECHINGER 1989;BOULOS 2000). In general these results agree with those of MAYER & EHRENDORFER (1999), CAPUTO et al (2004) and AVINO et al (2009).…”

“…VERLÀQUE (1985b) investigated the pollen and chromosome morphology of Cephalaria syriaca, and showed that it has tricolpate pollen and a dysploidy (2n = 10), although the majority of the annuals species of the whole genus has (2n = 18). In cladistic and molecular studies (CAPUTO & COZZOLINO 1994;CAPUTO et al 2004;AVINO et al 2009), Cephalaria forms a clade with Knautia, Pterocephalidium and Dipsacus.…”

“…Recently, CAPUTO et al (2004) and AVINO et al (2009) presented phylogenetic relationships among species of Dipsacaceae, and they separated Lomelosia and Pycnocomon in one clade, both in a sister group with a clade containing Pterocephalus, Scabiosa and Sixalix, and the rest of taxa in the other clade.…”

“…CAPUTO & COZ- ZOLINO (1994) presented a cladistic study of 13 genera of the family Dipsacaceae based on morphological and palynological characters, and they divided Dipsacaceae into two major clades, one includes Dipsacus and Cephalaria, the other including the remaining genera. CAPUTO et al (2004) Cephalaria. AVINO et al (2009) studied 35 species from the Dipsacaceae based on sequence data from chloroplast (trnL intron, trnL-trnF intergenic spacer, psbB-psbH gene complex) and nuclear genomes (ITS1 and ITS2), and they show that Dipsacaceae is a monophyletic group.…”

Pollen morphology of nine species belonging to four genera: Cephalaria, Pterocephalus, Scabiosa, and Lomelosia of Dipsacaceae in Egypt has been investigated by light microscope (LM) and scanning electron microscopy (SEM). Pollen shape, size, exine ornamentation, number and characters of apertures present powerful characters for distinguishing between species. The pollen grains were tricolpate and triporate. Their shapes vary from spheroidal to oblate-spheroidal. Regarding the position of apertures, three types can be recognized viz., circumaperturate, angulaperturate, and planaperturate. Concerning sculpturing of the exine in proximal face, two different pollen types can be distinguished viz., spinulate and gemmate types. The exine ornamentation was found useful to distinguish between closely related genera such as Scabiosa and Lomelosia. A diagnostic key is given for all studied taxa based on palynomorphological characters.

Palynology gives the evidence for identification and elimination of taxonomically complex genera. Pollen morphology of nine species (three subg., three sect.) of the genus Cephalaria Schrad. was studied using light microscopy and scanning electron microscopy. Pollen grains of all investigated species are triporate, suboblate to subprolate (P/E = 0.75-1.28), and large-sized (P = 58.52 μm-114.38, E = 63.84-119.70 μm). The outline of pollen grains in equatorial view is circular or elliptic, in polar view circular, circular-triangular, or triangular. Pores are distinct, lolongate, elliptic, or circular, with an annulus, operculum, and distinct or indistinct, wide halo surrounding the aperture. Exine sculpture is echinate-microechinate or echinate-microechinatenanoechinate. Additional diagnostic characters at the species level in Cephalaria Schrad. that can be used for the purposes of taxonomy are size of pollen grains and pores, the shape of pores, the width of the annulus, structure of the exine, dimension of echini and microechini, location of microechini, and presence/absence of nanoechini. Palynomorphological data are compared with the taxonomical classification system of investigated taxa. It is shown that pollen grains morphology of the genus Cephalaria Schrad. is similar to the pollen morphology of the genus Dipsacus L., which confirms their inclusion in the Dipsaceae tribe.

A phylogenetic study of Dipsacaceae, a Mediterraneancentered clade in the Dipsacales, was conducted using nuclear ITS and three chloroplast markers (atpB rbcL, trnL trnF, trnSUGA trnGGCC). This is the first molecular study to assess Dipsacaceae phylogeny in detail, and includes representatives from all major subclades. Maximum parsimony, maximum likelihood, and Bayesian analyses were carried out on the ITS and plastid datasets separately and in combination. For the most part, the ITS and plastid datasets resulted in similar topologies, and the combined data yielded a wellresolved estimate of Dipsacaceae phylogeny. A small Asian clade composed of Bassecoia and Pterocephalodes hookeri is resolved as sister to the rest of Dipsacaceae. Scabioseae s. str. (Scabiosa, Sixalix, Pterocephalus s. str., Lomelosia , Pycnocomon) and a "Dipknautid" clade (Dipsacus, Cephalaria, Knautia, Pterocephalidum, Succisa, Succisella, Pseudoscabiosa) form the two major lineages within Dipsacaceae. Most of the previously recognized genera are recovered as monophyletic, with the exception of Pycnocomon, which is nested within Lomelosia. We discuss the taxonomic implications of these results and their significance for understanding character evolution, particularly of the epicalyx in relation to seed dispersal.
