Abstract: The genus Peperomia includes 1,500-1,700 accepted species, making it one of the giant genera ofangiosperms. The infrageneric classification usually adopted is that of Dahlstedt (1900) which divides Peperomia into 9 subgenera, 7 sections and 4 subsections. In 1930, two of these sections were treated comparably with Dahlstedt's subgenera, making a total of 11 primary subdivisions of Peperomia. Later, different authors added a few more subgenera to include some island species. The names of only a few subgenera, sections or subsections of Peperomia have been typified. In this paper, we present a survey of all subgenera, sections and subsections described in the genus Peperomia and we designate nomenclatural types for names that have not yet been typified.

Abstract: Three Surirella taxa described by O.Muller from material collected at the beginning of the 20(th) century in Lakes Malawi and Malombe were re-evaluated, and lectotypes are assigned from the original material. One infraspecific taxon, S. nyassae var. sagitta, was synonymized with the nominate variety of S. nyassae and one forma, S. malombae f. acuta, was synonymized with S. malombae. As S. malombae is very rare in the original material from Lake Malombe, an epitype was also assigned from material collected at the end of the 19(th) century in Lake Victoria. Light and scanning electron microscopic information is given for these two taxa; their distribution in Africa and their habitat preference is summarized from the literature. A third, closely related taxon which was regularly observed in Lake Tanganyika is here described as Surirella chepurnovii sp. nov.

Abstract: Lectotypes are confirmed or designated here for the 13 names coined by Antonio Jose Cavanilles that were either described, or today are recognised as, members of the large genus Solanum (Solanaceae): Solanum betaceum, S. elaeagnifolium, S. fructotecto, S. lanceolatum, S. lentum, S. parviflorum, S. phyllanthum, S. pinnatum, S. pomiferum, S. pygmaeum, S. triquetrum, Triguera ambrosiaca and T. inodora . A brief introduction assesses the importance of Cavanilles to the botany of his time, and identifies difficulties in lectotypifying names coined by him. The currently accepted name for each taxon is given. Each typification is accompanied by a discussion of the reasoning behind the choice of specimen, and all lectotypes are illustrated.

Abstract: Flora Caroliniana (1788), by Thomas Walter, was the first treatment of American plants to employ the binomial nomenclature and sexual classification system of Linnaeus. Many of its species were new to science, and their names remain important in documentation of the southeastern American flora. But Walter kept no herbarium. Though types have been chosen for a few of Walter's names, a large proportion of his new species remain untypified. A portion of these species is addressed here, with selection of appropriate neotypes or epitypes to represent 43 Thomas Walter names.

Abstract: Four Cretaceous taxa of fossil platanoid leaves are revised based on leaf macromorphology. They are accommodated in the morphogenus Ettingshausenia Stiehler. Three species are from the Cenomanian Peruc Korycany Formation of the Bohemian Cretaceous Basin: Ettingshausenia cuneifolia (Bronn) Stiehler, Ettingshausenia bohemica (Velenovský) comb. nov. and Ettingshausenia laevis (Velenovský) comb. nov., whereas Ettingshausenia senonensis (Knobloch) comb. nov. is from the Senonian of the South Bohemian Basins. All four are described, including their typification and synonymy, and their diagnoses are emended to permit comparison with similar European Cretaceous taxa. Anatomical details of E. cuneifolia and E. laevis are described and discussed based on SEM studies of their cuticle.

Abstract: The identity of two species of Lecanora is discussed in accordance with a taxonomic revision of the L. dispersa group in North America. Original material of L. fl otoviana Spreng., recently discovered at GOET, differs in morphology and chemical content from the entity currently known by that name, and does not belong to the L. dispersa group but is a little-understood species. Consequently, L. fl otoviana is excluded from the group, and L. semipallida H. Magn. is shown to be the correct name for the common, widespread member of the L. dispersa group hitherto known as L. fl otoviana (auct. non Spreng.). Lecanora xanthostoma Cl. Roux is considered to be conspecifi c with L. semipallida and is therefore reduced to synonymy.

Abstract: Types for the names Barbula saxicola Lamy, Barbula subulata var. longifolia Kindb., Syntrichia alpina Brid., Tortula inermis var. submarginata Schiffn., and Tortula subulata var. compacta Schiffn., are designated here. Syntrichia alpina is considered conspecific with T. subulata Hedw., with which Tortula inermis var. submarginata and T. subulata var. compacta are also synonymized, as is Barbula subulata var. longifolia with T. schimperi M.J. Cano & al. Barbula saxicola is here considered to apply to the species currently known as Dialytrichia fragilifolia (Bizot & Cl. Roux) F. Lara; as B. saxicola has priority, this necessitates the new combination D. saxicola (Lamy) M.J. Cano.

Abstract: Gagea chrysantha Schult. & Schult. f., Gagea dubia A. Terracc., Gagea dubia var. foliosa A. Terracc., Gagea durieui Pari., Ornithogalum fibrosum Desf. (basionyme de Gagea fibrosa (Desf.) Schult. & Schult. f.), Ornithogalum granatellii Pari. (basionyme de Gagea granatellii (Pari.) Pari.) et Gagea mauritanica Durieu sont typifies. La valeur taxonomique de chacun de ces sept taxons est discutee.

Abstract: The 1986 neotypification of Mesophyllum lichenoides (J. Ellis) Me. Lemoine, type species of Mesophyllum (Hapalidiaceae, Corallinales, Rhodophyta), has to be superseded because the International Code of Botanical Nomenclature rules governing the selection of types have changed, and the new rules are retroactive. In accordance with the present rules, an illustration in the original account of the species is designated here as lectotype, and the superseded neotype is designated here as epitype. Relevant historical information and nomenclatural details associated with these changes are presented.

Abstract: The following nomenclatural adjustments are proposed for Draba to make the names available for the forthcoming account of the Brassicaceae in the Flora of North America. Three new species of Draba (D. abajoensis, D. malpighiacea, and D. santaquinensis) are described, and two new combinations (D. bifurcata and D. serpentina) are validated. Notes on the delimitation, distribution, or typification of D. corrugata, D. cyclomorpha, D. demareei, D. helleriana, D. lemmonii, D. longisquamosa, D. novolympica, D. oreibata, D. paysonii, D. petrophila, D. saxosa, D. spectabilis, and D. viridis are presented. Draba helleriana var. blumeri, D. paysonii var. treleasii, and D. spectabilis var. glabrescens are reduced to synonymy under D. petrophila, D. novolympica, and D. abajoensis, respectively.

Abstract: Descriptions and illustrations of three new Brazilian species of the genus Rauvolfia L. (Apocynaceae, Rauvolfioideae), R. capixabae I. Koch & Kinoshita-Gouvea, R. gracilis I. Koch & Kinoshita-Gouvea, and R. pruinosifolia I. Koch & Kinoshita-Gouvea, are presented. Rauvolfia blanchetii A. DC., R. mollis S. Moore, and R. divergens Markgraf are newly synonymized under R. ligustrina Willdenow, R. pernambucensis Emygdio under R. moricandii A. DC., and R. sessilifolia S. Moore under R. weddelliana Muller Argoviensis. Lectotypes for R. blanchetii and R. ternifolia Kunth are designated; furthermore, comments to clarify the complicated typification of R. ligustrina and R. ternifolia are presented.

Abstract: In this study, 16 new nothotaxa (7 of them previously known but invalidly published) are described. Some of them are illustrated and accompanied by distribution maps, and type material are deposited in the Herbarium TFC of the University of La Laguna. Other 17 new names (13 nothosections and 4 nothospecies) as well as 2 new combinations are proposed. Additionally, typification of Aeonium x burchardii and validation of the names A. x bollei, A. x lemsii, A. x lidii, A. x praegeri, A. x sventenii and Aichryson x intermedium are provided.

Abstract: Recently two new localities of Gundelia have been found in Armenia (VITEK & al. in prep.). These populations are morphologically different from the populations of Gundelia known up to now in Armenia, which have been called Gundelia tournefortii L. in the Flora of Armenia (AVETISIAN 1995 including G. rosea as synonym) and Flora USSR (VASIL'CHENKO 1961). Before classifying these new entities in any way, it is necessary to fix the application of the name Gundelia tournefortii which has been poorly understood and often used ambiguously.

Abstract: Typification of the 13 validly published, pre-1958 names of Helichrysum taxa based on Sicilian material is reassessed. Five of the types designated by Galbany-Casals & al. in their recent studies are confirmed (in some cases with additional precision), two neotypes proposed by them are superseded by lectotypes, and six lectotypes are newly designated. The correct name of the species known as H. rupestre, an illegitimate name, is H. panormitanum (or, if taken in a wide sense, H. pendulum).

Abstract: Cheilanthes incisa, a small and rare endemic fern of Rio de Janeiro State (Brazil), was described in 1859. Hypolepis serrata, published ten years later, is usually considered a taxonomic synonym. Both names have typification problems, addressed here by designation of a neotype for C. incisa and selection of a lectotype of H. serrata from among Glaziou materials cited by Fee. Epidermal characteristics and spores of C. incisa are described for the first time and their diagnostic value assessed. Taxonomic relationships between C. incisa and putatively related cheilanthoid ferns are also discussed.

Abstract: Otto Muller's published data and pictures of Navicula elkab were re-evaluated and compared with literature data and a Holocene sediment core material from Ounianga (Chad, Africa). A valid name under Craticula is provided and a lectotype and an epitype are selected. An unusual siliceous covering over the valves is discussed.

Abstract: The Linnaean name Hieracium umbellatum has generally been understood in a very strict and clear sense. The original material comprises three specimens and a few illustrations, with a lectotype designated here in Burser's Hortus siccus (UPS). The earlier choice published by W. Lack was made from non-original material and was therefore not effective. The application of this name is confined to a variety generally known as H. umbellatum var. commune Fr. nom. illeg. (restricted here to the forms with almost entire, sublinear leaves), most proximate to H. umbellatum var. coronopifolium (Bernh. ex Hornem.) Wimm. et Grab.

Abstract: Gagea amblyopetala var. elata A. Terracc., Gagea aitchisoniana A. Terracc., Gagea linearifolia A. Terracc. (≡Gagea sintenisii Pascher) et Gagea foliosa var. micrantha Boiss. (basionyme de Gagea micrantha (Boiss.) Pascher) sont typifies, Chaque type est illustre and discute. La valeur taxonomique de ces taxa est discute.

Abstract: The results of the generalization of lithologic-facial and paleogeographic reconstructions and genetic formational analysis of the various metalliferous high-carbonaceous Phanerozoic sedimentary complexes are presented and systematized. The factors predetermining the origin of ore concentrations of gold and copper are specified.

Abstract: Six taxa described by Miki were lectotypified using the specimens deposited in OSA; Myriophyllum oguraense, Najas oguraensis, Najas tenuicaulis, Ruppia truncatifolia, Utricularia minor var. multispinosa and U. tenuicaulis.

Abstract: Eleven lectotypes and one neotype are designated for the names of the 12 Latin American species in the genus Fossombronia Raddi that have not been previously typified. The entries for each are given in alphabetical order with author citation, place and date of publication, herbarium of deposit and supporting information. The original protologue and images of the herbarium label for each type specimen can be viewed at the URL .

Abstract: GALAN DE MERA, A. (2007). Typification of Arisarum simorrhinum Durieu (Araceae). Candollea 62: 61-64. In English, English and French abstracts. The name Arisarum simorrhinum Durieu (Araceae) is lectotypified. This Macaronesian and southwestern European and Mediterranean species was described from Algeria.

Abstract: A new status and a new synonym in the genus Syringa are proposed based on population sampling, examination of herbarium specimens, character analysis and multivariate analysis. Syringa wolfii C. K. Schneid. is here treated as S. villosa ssp. wolfii rather than S. reflexa ssp. wolfii, and its lectotype is designated here. Also designated are the lectotypes of five synonyms: S. bretschneiderii, S. emodi var. rosea, S. villosa var. hirsuta, S. formosissima, and S. robusta.
