Mota, J. F., J. A. GARRIDO-BECERRA, F. J. PÉREZ-GARCÍA, A. J. SOLA & F. VALLE (2010). Use of the Multi-Response Permutation Procedure and Indicator Species Analysis for the statistical classification of the gypsicolous Iberian scrub communities. Candollea 65: 117–134. In English, English and French abstracts.

The Iberian gypsophilous scrub communities, belonging to the phytosociological order Gypsophiletalia (Bellot 1952) Bellot & Rivas Goday 1957, are considered as priority ecosystems for conservation because of their richness in endemic and s tenoecious species. Six complete revisions and a number of partial revisions of Gypsophiletalia have been published up to now, producing over 100 phytosociological tables and about 800 vegetation relevés. This large amount of information has been analysed here to reevaluate this phytosociological order. The statistical techniques of Multi-Response Permutation Procedure (MRPP) and Indicator Species Value (IV) have been carried out on this data set and the results have been compared with data obtained from cluster analysis. Our results reveal the inconsistency and lack of objectivity of some of the previous syntaxonomical typologies. We conclude that objective classifications must be based on clearly defined criteria easy to replicate in following the same procedures. Both IV and MRPP have proved useful techniques, not only for the clarification of the diagnostic potential value of taxa, but also for the production of objective syntaxonomical typologies.

OLONOVA, M. V. & W. L. CHEN (2010). Systematic revision of the Poa sphondylodes Trin. complex (Poaceae). Candollea 65: 135–141. In English, English and French abstracts.

The taxonomic status of the Poa sphondylodes Trin. complex (Poa sect. Stenopoa Dumort., Poaceae) is discussed. Two subspecies are recognized: Poa sphondylodes subsp. kelungensis Ohwi, restricted to Taiwan and Poa sphondylodes subsp. sphondylodes, with a wide distribution in the eastern part of China, Korea, Japan, and the Far East of Russia. This latter includes 5 varieties, Poa sphondylodes var. sphondylodes, Poa sphondylodes var. erikksonii Melderis, Poa sphondylodes var. subtrivialis Ohwi, Poa sphondylodes var. macerrima Keng, and Poa sphondylodes var. plurifolia (Keng) Olonova & W. L. Chen, which is validated. A lectotype is designated for the name Poa sphondylodes. Identification keys are given.

SALES, F. & I. C. HEDGE (2010). Three perplexing names of species of Campanula L. Candollea 65: 143–146. In English, English and French abstracts.

The status of three “Oriental” names of species of Campanula L., Campanula asperrima Zuccagni, Campanula decurrens Zuccagni and Campanula ajugifolia Schult. is investigated. It is impossible to establish with any confidence the identity of the first two because there are no known type specimens and their protologues are imprecise. Campanula ajugifolia, was considered as an “incertae sedis“ and is here typified by a specimen in the Willdenow herbarium at Berlin. It is shown that Campanula ajugifolia is the earliest name for the Turkish endemic species currently known as Campanula argaea Boiss. & Balansa.

Stančic, Z., K. Žganec & S. Gottstein (2010). Marshland vegetation of Plitvice Lakes National Park (Croatia). Candollea 65: 147–167. In English, with English and French abstracts.

The Plitvice Lakes National Park is located in a mountainous region of Croatia, and is of world renown for its karstic lakes separated by tufa barriers, and its waterfalls. In many places around the lakes, and along the streams, marshland vegetation of the class Phragmito-Magnocaricetea Klika 1941 has developed. This vegetation has been studied in accordance with the Braun-Blanquet methodology. As a result, 13 communities were distinguished, three being found for the first time in Croatia: Caricetum rostratae Rübel 1912, Eleocharitetum uniglumis E. G. Almq. 1929 and Equisetetum fluviatilis Steffen 1931. Through numerical classification it was found that traditionally accepted communities match very well with the clusters obtained. Some ecological characteristics of the communities were estimated by calculating Ellenberg indicator values. Through analysis of plant life forms, specific features of marshland communities were also derived, especially at the level of vegetation alliances. The most common association of the study area is Phragmitetum australis Schmale 1939, which spreads in habitats of Ligularia sibirica (L.) Cass., a rare and threatened species throughout Europe. From the aspect of nature conservation, marshland vegetation in the Plitvice Lakes shows both positive and negative features. There is a positive effect in the enrichment of biodiversity, while most communities have developed as a consequence of the eutrophication of oligotrophic karstic lakes, which must be considered negative.

Price, M. J. (2010). Lectotypification of the name Tetraphis pellucida Hedw. (Bryophyta). Candollea 65: 15–19. In English, English and French abstracts.

Selection of a lectotype for the name Tetraphis pellucida Hedw. (Bryophyta, Tetraphidaceae) is necessary as two original Hedwig herbarium sheets, containing multiple stems, are present in the Hedwig-Schwägrichen collection housed in G. Protologue information and label information do not entirely correspond for either of the herbarium sheets, however a stem of Tetraphis pellucida from one of the two sheets resembles the stem depicted in Hedwig's original illustration. This stem conforms to the protologue as well as to the modern concept of this taxon and is proposed as the lectotype for this name herein

Morales, M. & R. H. Fortunato (2010). Taxonomic and nomenclatural novelties in Mimosa L. subser. Mimosa (Leguminosae) in Austral South America. Candollea 65: 169–184. In Spanish, English and French abstracts.

In the present taxonomic revision of Mimosa L. subser. Mimosa (Leguminosae, Mimosoideae) from Austral South America, the following taxa are recognized: Mimosa velloziana Mart. var. velloziana, Mimosa sensibilis Griseb. var. sensibilis, Mimosa sensibilis var. aquidabani Barneby, as well as Mimosa debilis var. debilis Willd., Mimosa debilis var. amnis-mortium Barneby and the new combination Mimosa debilis var. angusta (Benth.) M. Morales & Fortunato. New synonymies are proposed for Mimosa debilis var. debilis and Mimosa sensibilis var. sensibilis. On the basis of the morphologic analysis, the varietal division of Mimosa velloziana and the variability of Mimosa debilis complex are also discussed.

A lectotypification of the name Allaeanthus kurzii Hook. f. (Moraceae, tribe Moreae) (≡ Broussonetia kurzii (Hook. f.) Corner) is proposed. The lectotype specimen, Griffith (Kew Distrib. 4675), is kept at the Royal Botanic Gardens, Kew (K).

Jeanmonod, D. (2010). Typification of the Corsican taxa in Litardiere herbarium (G). Candollea 65: 23–44. In French, English and French abstracts.

The Litardière herbarium (deposited in G) contains many types that have previously been overlooked. The aim of this work was to identify all the new Corsican taxa then to extract all the type specimens from Corsica present in that herbarium and reported by Litardière and other botanists. 97 new Corsican taxa have been identified, and for 91 taxa, 135 type specimens (including duplicates) were found. This type material has been carefully typified as 36 holo-, 49 lecto-, 2 isolecto- and 47 syntypes. 45 taxa were described by R. de Litardière himself, 30 by K. H. Zahn (for Hieracium L.), 9 by J. L. van Soest (for Taraxacum F. H. Wigg.) and 13 by other botanists (J. Arènes, J. M. C. Arvet-Touvet, J. Gamisans, R. Maire, K. Ronniger, G. Rouy, A. Saint-Yves and T. G. Yuncker). These taxa belong to 20 families and 33 genera, but about the half (48) belong to Asteraceae, and are essentially species from Taraxacum and Hieracium.

Chiron, G. R., G. Guignard & G. Barale (2010). Contribution of morphometry to the taxonomy of Baptistonia Barb. Rodr. (Orchidaceae). Candollea 65: 45–62. In English, English and French abstracts.

The genus Baptistonia Barb. Rodr. (Orchidaceae) includes 23 species, all endemic to Brazil. As problems occur to differentiate some taxa of this genus, because of their hypothetical hybrid origine, the present study aims to use morpho metry as an attempt to solve these issues. Twenty six floral morphometric characters were measured on 146 specimens, and analysed using multivariate analysis, such as Neighbour Joining Analysis (NJA), Principal Coordinates Analysis (PCoA) and Discriminant Analysis (DA). Morphometric data proved to be very useful for species delimitation, and a statistical tool here is presented in clearly separating taxa within the confusing groups. Hybrid nature of two species is presented. The contribution of morphometry in phylogeny for Baptistonia is discussed.

MARTÍNEZ CARRETERO, E., A. DALMASSO, J. MÁRQUEZ & M. MARTINELLI (2010). Plant communities and phytogeographical units from NW San Juan Province (High Central Andes of Argentina). Candollea 65: 69–93. In English, English and French abstracts.

Vegetation of the High Central Andes of Argentina was studied in NW San Juan Province (MAB Reserve of San Guillermo) from a phytosociological point of view. Four new associations are proposed: two shrubland associations, Artemisietum paramilloensis and Lycio-Ephedretum rupestri, and two grassland associations, Jaravetum chrysophyllae and Jaravetum absconditae. The latitudinal and altitudinal boundaries of the Monte, Puna and High Andean phytogeographic provinces were established for the study area. This area constitutes the floristic and biogeographic transition between northern (Bolivia) and southern (Mendoza, Argentina) Puna elements, belonging to the Calamagrostietea vicunarum class, and to the Stipo-Lycietea class, respectively.
