De Gennaro, D., R. Pozner & O. Morrone (2010). Foliar anatomy of Sacciolepsis Nash (Poaceae). Candollea 65: 197–210. In Spanish, English and French abstracts.

Leaf anatomy study of the genus Sacciolepis Nash (Poaceae, Panicoideae, Paniceae) is presented and discussed. It is based on the analysis of epidermis in paradermal view and blade sections of 18 species of this genus. It is concluded that the leaf anatomy does not support previous proposals of subdivisions of Sacciolepis, nor correlates with the geographical distribution of species, and it has a very limited predictive value of the environment where these species grow. An identification key, for the species of the genus Sacciolepis based on the leaf anatomy, is provided.

Jeanmonod, D. & A. Schlüssel (éd.) (2010). Notes and contributions on Corsican flora, XXIII. Candollea 65: 267–290. In French, French and English abstracts.

These “notes” deal with 102 noteworthy taxa amongst which 12 are new introduced species to the island's flora: Chamaerops humilis, Bothriochloa barbinodis, Anthemis cretica subsp. cretica, Arctotheca calendula, Crepis nicaeensis, Leontodon hispidus subsp. hispidus, Soliva sessilis, Saponaria ocymoides subsp. ocymoides, Silene italica, Euphorbia cyparissias, Anthyllis vulneraria subsp. carpatica and Physalis peruviana. New localities are given on one hand for 39 taxa considered as “very rare” (RR) out of which 9 (Freesia alba, Serapias strictiflora, Elytrigia repens, Hordeum marinum subsp. marinum, Crepis bursifolia, Crepis foetida subsp. rhoedifolia, Gleditsia triacanthos, Fumaria flabellata and Galium minutulum) become “rare” (R).

FENU, G., E. MATTANA, A. CONGIU & G. BACCHETTA (2010). The endemic vascular flora of Supramontes (Sardinia), a priority plant conservation area. Candollea 65: 347–358. In English, English and French abstracts.

The main aim of this work is to present a checklist of the endemic vascular flora of the Supramontes region (Central Eastern Sardinia) in order to classify this area in the Sardinian biogeographic subprovince and to better assess its conservation priorities. It is one of the most interesting regions of the Island and spreads for 335 km² from the inland limestone massif to the Orosei gulf. This work was based on bibliographic and herbarium studies, integrated by several field surveys carried out from 2004 to 2009. In this study 138 endemic taxa, belonging to 98 genera and 42 families, have been found, with 92 of which being species, 40 subspecies, 5 varieties and 1 hybrid. The analysis of biologic and chorologic data highlighted the peculiarities of this territory. Due to the relatively high number of Supramontes exclusive endemics and to the geologic and geomorphologic peculiarities, it is here proposed a biogeographic classification for these territories and the identification of an autonomous biogeographic sector divided in two distinct subsectors. According to the recent conservation policies at local level, we propose the definition of micro hotspots for this sector, which hold ca. the 40% of the endemic flora of Sardinia, and the concept of nano hotspots for three narrows areas with an exceptional concentration of endemic species, which represent less than 1% of the whole sector surface and whose in situ protection may allow conserving of more than 80% of the vascular endemic flora of this sector.

CALLMANDER, M. W., P. B. PHILLIPSON &; L. GAUTIER (ed.) (2010). Notes on the flora of Madagascar, 1–5. Candollea 65: 359–376. In English, English and French abstracts.

Ongoing research on Madagascar's flora is revealing numerous taxonomic novelties and nomenclatural inconsistencies, and providing new data on species distribution. This is the first article in a series that aims to provide the botanical community working on the flora of Madagascar an opportunity to publish short communications on these topics. — Note 1. Dealing with Indigofera nivea (Leguminosae) — a new name for Madagascar and a new combination for Africa, by Martin W. Callmander, Jean-Noël Labat & Brian D. Schrire. The authors resolve the application of “Indigofera nivea”. Indigofera nivea Spreng. is a valid name for an African species now referred to the genus Indigastrum Jaub. & Spach, for which a new combination, Indigastrum niveum (Spreng.) Schrire & Callm., is published. The illegitimate later homonym by Viguier refers to a species endemic to Madagascar, for which a new name, Indigofera viguieri Callm. & Labat, is published. — Note 2. Distribution of Cyperus chamaecephalus Cherm., a forest undergrowth species with inconspicuous inflorescences, by Laurent Gautier, Louis Nusbaumer, Isabel Larridon & Martin W. Callmander. The distribution of Cyperus chamaecephalus Cherm., a frequently overlooked forest undergrowth species with inconspicuous inflorescences, has been very poorly documented. The authors report several recent discoveries which permit a more complete understanding of its geographical distribution in Madagascar's lowland and mountain rainforests. — Note 3. The genus Korthalsella (Santalaceae) in Madagascar, by Martin W. Callmander, Peter B. Phillipson, Roy E. Gereau, Gérard Aymonin & Amir Sultan. The authors present a review of the genus Korthalsella Tiegh. (Santalaceae) for Madagascar. The identity of Korthalsella taenioides (Juss.) Engl., consistently confused by previous authors, is discussed in detail. Three other species known to occur in Madagascar are enumerated: Korthalsella gaudichaudii (Tiegh.) Lecomte, Korthalsella madagascarica Danser and Korthalsella japonica (Thunb.) Engl. — Note 4. Forsyth-Major 348: four collections, two names, all referring to Mimulopsis madagascariensis (Acanthaceae), by Laurent Gautier & Martin W. Callmander. Among Forsyth-Major's botanical collections, an individual collection number often comprises a set of specimens representing different gatherings. The authors clarify one of these collection sets: Forsyth-Major 348, on which the names Strobilanthes isoglossoides Lindau and Mimulopsis forsythii S. Moore are based, unambiguously designating type material. Both taxa are placed in synonymy under Mimulopsis madagascariensis (Baker) Benoist. — Note 5. The genus Brackenridgea A. Gray (Ochnaceae) in Madagascar, by Martin W. Callmander, Sven Buerki & Peter B. Phillipson. The two Malagasy species described in Pleuroridgea Tiegh. (Ochnaceae) are lectotypified and formally transferred to Brackenridgea A. Gray. The needed combinations: Brackenridgea madecassa (H. Perrier) Callm. and Brackenridgea tetramera (H. Perrier) Callm. are provided. Conservation status assessments for the two species are also provided.

GRONER, U. (2010). Calicioid lichens and fungi in the Muota Valley, central Switzerland: high species diversity in a small area. Candollea 65: 377–391. In English, English and French abstracts.

An inventory of the calicioid lichens and fungi of the Bödmeren Forest region in the Muota Valley, central Switzerland, produced no less than 51 lichenized and non-lichenized taxa on bark and wood. This mainly subalpine spruce forest in the Prealps hosts the most diverse calicioid flora in Switzerland today and a similarly rich flora from a comparably small area is unknown from neighbouring countries. Calicium denigratum (Vain.) Tibell and Chaenothecopsis oregana Rikkinen are new to Switzerland. Calicium adaequatum Nyl., Chaenothecopsis tasmanica Tibell and Chaenothecopsis vainioana (Nádv.) Tibell are also reported for the first time from this region. Chaenotheca chrysocephala (Ach.) Th. Fr., Calicium viride Pers., Chaenotheca trichialis (Ach.) Th. Fr. and Microcalicium disseminatum (Ach.) Vain. are the most frequent species, the majority of the other taxa are uncommon or rare. The diversity of the calicioid (and other) species is due to several favourable conditions, such as the presence of old-growth forest stands and the occurrence of standing dead trees. More than 40% of the recorded lichenized calicioid taxa are threatened; the state of the poorly known non-lichenized calicioids is undetermined as they were not evaluated in the “Red List”.

RAMELLA, L. & P. PERRET (ed.) (2010). Notula ad Floram paraquaiensem, 106. Candollea 65: 393–402. In Spanish, French and English abstracts.

Thirty-fifth installment of a series dedicated to the presentation of taxonomic, nomenclatural or floristic novelties in relation with the project “Flora del Paraguay” as well as complements to already published treatments. Organizational information and accounts on the advancement of the project are sometimes added by the editors. — Notula 106. Synopsis and typifications of the species of the genus Oxypetalum R. Br. (Asclepiadaceae) in Paraguay, by Jorge Fontella Pereira, Sergio A. Cáceres Moral & Monique Britto de Goes. The authors present a key and a synopsis of the 31 species and 3 infraspecific taxa of the genus Oxypetalum R. Br. in Paraguay. They validate the new combination Oxypetalum martii var. nanum (Malme) Fontella & S. A. Cáceres and publish a new synonym. The authors lectotypify: Oxypetalum acerosum Malme, Oxypetalum clavatum Malme, Oxypetalum ceratostemma Malme, Oxypetalum marginatum Malme. They correct the wrong citation of the syntypes in the protologue of Oxypetalum acerosum Malme and specify the holotype of Oxypetalum aurantiacum Malme not mentioned in the protologue.
