The genus «Aristolochia» L. (Aristolochiaceae) in Italy

Abstract A taxonomic revision of the Italian species of Aristolochia L. has been carried out. Evidence and information were drawn from the study of living plants and herbarium exsiccata, including type material. The attention was focused on the flower morphological characters, frequently disregarded, and on the chromosome numbers. This resulted in the systematic, nomenclatural and chorological rearrangement of the genus with special regard to Italy. Ten taxa were recognized to grow in Italy against the seven or eight entities listed in recent Floras: A. altissima Desf. (Sicily); A. clematitis L. (continental Italy, Sicily); A, rotunda L. (mainland Italy, Tuscan Archipelago, Ischia, Sicily); A. insularis Nardi et Arrigoni (Sardinia); A. clusii Lojacono (S-Italy, Sicily); A. navicularis Nardi, sp. nov. (Sardinia, Egadi Is.); A. pallida Willd. (continental Italy); A. lutea Desf. (mainland Italy, Tuscan Archipelago, Sicily); A. tyrrhena Nardi et Arrigoni (Sardinia); A. sicula Tineo (Sicily). A. pistobchia L. ...

Anchusella, a new genus ofBoraginaceae from the Central-Eastern Mediterranean

The two closely related speciesLycopsis variegata andAnchusa cretica, formerly placed inAnchusa subg.Rivinia, were compared with the type species ofLycopsis andAnchusa, on the basis of a set of macro and microcharacters. The presence of only two fertile stamens as well as other peculiar characters in flower structure, androecium, gynoecium, pollen and fruit, supports the institution of the new genusAnchusella, consisting ofA. variegata andA. cretica. Karyological and eco-chorological aspects are consistent with morphological data in pointing to the autonomy of this genus, which appears characterized by autapomorphic, advanced traits.

Molecular evidence of polyphyletism in the plant genus Carum L. (Apiaceae)

An analysis of internal transcribed spacer (ITS) DNA sequences of the four species of Carum L. (Apiaceae) known in Italy revealed that this genus is polyphyletic. Maximum parsimony with bootstrap resampling, maximum likelihood and Bayesian inference analyses resulted in three distinct clades: Carum carvi L. clustered within tribe Careae Baill. (former Aegopodium clade); Hellenocarum multiflorum (= Carum multiflorum), Carum heldreichii and Carum appuanum clustered within the tribe Pyramidoptereae Boiss.; and H. multiflorum and C. heldreichii formed a well supported clade. Since the sister group of H. multiflorum and C. heldreichii was Bunium elegans the autonomy of Hellenocarum from Carum is confirmed by our study. We also found that C. appuanum clustered separately from the other Carum species, with the closest related species appearing to be Scaligeria moreana but this still had few morphological similarities with C. appuanum.

The genus Aristolochia L. (Aristolochiaceae) in Greece

Summary After a systematic revision of the Greek Aristolochias, based on both dried and living material, 12 species, one of which represented by 1 subspecies and another by 2 subspecies, have been recognized to grow in the country: A. sempervirens L., A. hirta L., A. guichardii P.H. Davis et Khan, A. cretica Lam., A. incisa Duchartre, A. parvifolia Sm., A. pallida Willd. ssp. pallida, A. lutea Desf., A. elongata (Duchartre) Nardi, A. microstoma Boiss. et Spruner, A. rotunda L. ssp. rotunda, A. rotuncla ssp. insularis (Nardi et Arr.) Gamisans, A. clematitis L. A. hodamae Dingier is definitively proved to be synonym of A. hirta. A. rotunda ssp. insularis, previously known as endemic to the N-tyrrhenian area, is recognized as new to the Greek flora.

The phylogenetic relationships of Cynoglottis (Boraginaceae- Boragineae) inferred from ITS, 5.8S and trnL sequences

Abstract.A molecular phylogenetic analysis of Cynoglottis was performed to evaluate previous hypotheses based on non-molecular evidence concerning the position of this genus within Boraginaceae tribe Boragineae. ITS-5.8S and trnLUAA sequences from the nuclear and chloroplast non-coding genomes were obtained for four Cynoglottis taxa and selected members of the related genera Anchusa, Anchusella, Gastrocotyle, Brunnera and Pentaglottis. Cynoglottis is monophyletic, but neither trnL nor ITS support a close relationship with Brunnera, unlike previously supposed on morphological grounds. Brunnera is, instead, related to the southwestern European monotypic genus Pentaglottis, with which it forms a basal clade. ITS-5.8S sequences show that Anchusa thessala, a southeastern European annual species of Anchusa subg. Buglossellum, is sister to Cynoglottis and that the two taxa form a clade which also includes the Balkan endemic Gastrocotyle macedonica. Species of Anchusa subg. Anchusa form a separate lineage with high bootstrap support, suggesting that this heterogeneous genus is paraphyletic with respect to Cynoglottis. ITS sequences also discriminate between the Balkan-Apenninic diploid C. barrelieri and the Anatolian tetraploid C. chetikiana, albeit with low support. The molecular results are discussed in the light of karyological, morphological and chorological aspects.

The ultimate types ofAnchusa L. and Lycopsis L. (Boraginaceae)

The tribe Boragineae Bercht. & J. Presl was regarded by Johnston (1924) as a natural group of the Boraginaceae, consisting of closely related genera showing reticulate variation of several significant characters (see also Smith, 1932). Past taxonomic treatments largely depended upon the relevance attributed by different authors to such characters. One of the taxonomic problems concerns the delimitation of two Linnaean genera, Anchusa and Lycopsis, which in the past had mostly been separated by the flower zygomorphy typical of Lycopsis. Despite general agreement on the species names that provide the types of these two generic names, neither species name appears to have yet been typified.

Identification of « Cheilanthes fragrans » var. « gennarii » Fiori with « C. guanchica » Bolle and remarks on related taxa

Summary FIORI (Fl. Ital. Cryptog. Pterid.: 266–272. 1943) quotes five taxa for the fern genus Cheilanthes Swartz as growing in Italy, which he groups into two species: C. fragrans Webb et Berth, and C. persica (Bory) Mett. ex Kuhn. He divides C. fragrans into four varieties: var. α acrostica (Balbis) Fiori, var. β gennarii Fiori, var. γ commutata (Trevisan) Fiori and var. δ maderensis (Lowe) Fiori. As in other cases Fiori has applied here a very wide species concept. Experimental methods (VIDA et al. 1970, 1971) have shown that Fioris four varieties should be treated as separate species. We could correlate them as follows: var. α acrostica = C. pteridioides (Reichard) C. Chr.; var. β gennarii = C. guanchica Bolle (= C. svenienti Beni), until recently known only from the Canary Islands; var. γ commutata in Fioris concept was very close to C. corsica Reichst, et Vida, but it two cases he erroneously included C. maderensis in this taxon; var. δ maderensis = C. maderensis Lowe, which is an important ancestr...

Nomenclatural notes and typification in Sesleria Scop. (Poaceae)

After a close examination of the historical aspects of the typification of Sesleria caerulea, the correct names of the two allied species of the group are established as being S. caerulea (L.) Ard. and S. uliginosa Opiz. This permits unambiguous lectotypification of Sesleria. In addition, the types of the names S. albicans and S. uliginosa are designated.
