Orthotrichum handiense, sp. nov. from Fuerteventura, Canary Islands

A new epiphytic moss, Orthotrichum handiense F. Lara, Garilleti, & Mazimpaka, is described from the Jandia Peninsula (Fuerteventura, Canary Islands, Spain). The new species is included in section Pulchella Vent. and characterized by robustness, lanceolate leaves with recurved margins, immersed capsules, stomata cryptopore located in the neck, well developed prostome, peristome of 16 teeth and 16 segments, and calyptra and vaginula densely covered with slightly papillose hairs. Drawings and SEM micrographs of the main characters are given, and possible confusion with other taxa is discussed. During spring 1992, one of the authors (M. Brugu6s) collected bryophytes in the mountainous area of the Jandfa Peninsula, from the extreme south of Fuerteventura Island, in the eastern part of the Canarian Archipelago. One of the epiphytic samples collected from the beautiful shrub Asteriscus sericeus (L. fil.) DC. corresponds to the moss described here, a robust Orthotrichum that has an exclusive set of characters differentiating it easily from any other member of the genus. The Jandfa Peninsula that gives its name to the new moss, is an area that comprises a phanerogamic flora rich in local endemics; namely, the Zarza Peak (the highest peak) is the locus classicus of, among others, Bupleurum handiense Bolle, Echium handiense Svent., Ononis christii Bolle, and Argyranthemum winteri (Svent.) Humphries. Asteriscus sericeus itself is endemic to the isle, and the most characteristic plant of the Jandia summits, where it forms the dominant scrub. Its occurrence indicates the potential area of the ancient lauroid wood, which is nowadays represented by residual, small trees like Visnea mocanera. L. fil., Maytenus canariensis (Loes.) Kunkel & Sund., and Apollonias barbujana (Cav.) Bornm. The occurrence of lauroid wood (a xeric variant of the Canarian laurisilva), as well as that of the epiphytes that grow on the shrubs, is made possible by fog persistence and horizontal precipitation owing to trade winds, however the annual rainfall average is very low around 250-400 mm (Santos, pers. comm.). At present, the Jandfa peninsula is considered a natural area under protection of the Canarian government, but it is actually subjected to strong and uncontrolled grazing pressure, mainly by goats. Only two Orthotrichum species are known from Fuerteventura O. affine Brid. and O. diaphanum Brid.; both reported by Dirkse et al. (1993) on the basis of Malmes (1988) original records. Both species were found occurring on Asteriscus sericeus, but our gatherings from this shrub at Zarza peak contained only O. diaphanum and the moss described as new here. ORTHOTRICHUM HANDIENSE F. Lara, Garilleti & Mazimpaka, sp. nov. FIGS. 1-15 Planta robusta, ramosa, filidiis lanceolatis acutis vel acuminatis, marginibus variabiliter recurvatis cellulibusque cum papillis humilibus.

THE IDENTITY OF ENTOSTHODON DURIEUI AND E. PALLESCENS

Abstract As a result of the revision of herbarium specimens and literature records, an annotated checklist of bryophytes of the Balearic Islands is presented. The distribution by islands is provided for each of the 328 bryophytes taxa (one hornwort, 67 liverworts and 260 mosses) currently accepted in the archipelago. Thirty-six taxa are to be excluded or doubtful. The highest number of species is found in Mallorca (298 taxa), followed by Menorca (159 taxa), Eivissa (92 taxa), Formentera (52 taxa), Cabrera (33 taxa) and Dragonera (32 taxa). The species richness of Mallorca is due to the presence of mountains which in the Serra de Tramuntana, rise to 1445 m. That of Menorca is due to acidic substrate, which are rare in the other islands.

On the taxonomic status and distribution of Funaria durieui

Entosthodon durieui Mont. and E. pallescens Jur., two species with Mediterranean distributions are compared and are identical. A description and illustrations of E. durieui, incorporating spore morphology, are given. Entosthodon durieui was described by Montagne (1849) and E. mustaphae by Trabut (1886), both species from Algeria. They have also been reported from Israel and Spain. Bizot (1945) considered E. mustaphae synonymous with E. durieui. Allorge (1960) published descriptions and illustrations of both taxa. Juratzka (in Unger & Kotschy 1865) described Entosthodon pallescens from Cyprus, but details about calyptra and lid were not provided. Subsequently, this species has been recorded from many Mediterranean countries and islands (Balearic Island, Crete, Egypt, Greece, Italy, Israel, Sicily, Turkey, and Spain), central Asia, and Tenerife. Casares-Gil (1915) reduced E. physcomitroides CasaresGil & Beltrin reported from the Iberian Peninsula (Casares-Gil & Beltriin 1912), to a variety of E. pallescens. Loeske (1929) suggested the epithet mitratus because of its mitriform calyptra, even though details about calyptra were not provided in the original description of E. pallescens. It seems to have been understood that E. pallescens had a cucullate calyptra, which corresponds to the characteristic shape found in the genus Entosthodon; however, the presence of a mitriform calyptra can be found in the description of E. pallescens by Abramov et al. (1989). Comparative studies of E. durieui and E. pallescens have only been carried out by Loeske (1929) and Bilewsky (1965). Loeske doubted that there is any difference between these two species. Bilewsky tried to distinguish between them, but his conclusions are ambiguous and contradictory. Loeske also related E. durieui and E. mustaphae with E. commutatus Dur. & Mont., a species also described from the north of Africa. Thus, these three species appear as synonymous in Index Muscorum. In the Israel checklist (Herrnstadt et al. 1991), E. commutatus, E. durieui, and E. mustaphae are considered synonyms of E. attenuatus (Dicks.) Bryh. In the distribution maps of the bryophytes of the Iberian Peninsula (Casas et al. 1996), E. pallescens, E. durieui, and the varieties mitratus and mustaphae, have been shown in one single map, due to difficulties in distinguishing them. C reful research shows that E. durieui, E. commutatus, and E. attenuatus are not synonymous. Entosthodon commutatus has leaves tapering to long apiculate apices and long-lanceolate peristome teeth; these features serve to clearly distinguish it from E. durieui. Additionally, E. attenuatus can be differentiated by its cerise rhizoids, which are light brown in other taxa (Fife 1987). It is also worthwhile noting that E. durieui differs from other closely related species from the north of Africa which are included in the genus Funaria, such as F. saharae Trab., F. deserticola Trab., and F. nilotica Broth. Long lanceolate peristome teeth have been observed in the above species. Funaria mouretti Corb., from the North of Africa too, has denticulate leaves with excurrent nerve. Specimens classified as E. pallescens or as E. durieui present a set of characters that are not found in other species of the genus Entosthodon. The leaves are entire, elliptic to obovate or spathulate, marginal cells not differentiated, with a weak short nerve and an acute to obtuse apex. The pyriform capsule has a neck as long as the sporangium, the peristome teeth are rudimentary and short, with only 2 or 3 cell segments overhanging the capsule mouth. The spores are coarsely baculate-insulate and the mature calyptra has inflated and lobed bases with 3 or 4 slits. Entosthodon durieui and E. pallescens share the same habitat. All specimens have been collected on calcareous rocks and artificial walls in dry environments at low elevations. We conclude that E. durieui and E. pallescens are the same taxon. The name E. durieui takes priority. Entosthodon durieui belongs to the subgenus Entosthodon (Fife 1985): the exothecial cells are oblong with thick, radially cuneate walls and the mouth has the same diameter as the moist capsule. However, the calyptra is mitrate, as characteristic for the genus Physcomitrium. Spores are coarsely baculate-insulate, similar to those of E. tucsonii, which is considered by Fife (1985) as a species with anomalous spores, but rightly placed in subgenus Entosthodon. This ornamentation pattern is 0007-2745/98/133-136

Didymodon eckeliae (Pottiaceae), new to Europe

Funaria durieui, described from Algeria, is reported from the Iberian peninsula and the Canary islands. A new name, Entosthodon schimperi, is suggested.

New national and regional bryophyte records, 50

Abstract Bryum mildeanum, a rare species in the Iberian Peninsula, has frequently been confused with B. alpinum. In this study we provide new gametophytic and sporophytic (obtained by SEM) characters that can be used to separate the two and B. mildeanum is described and lectotypified. A molecular study based on two chloroplast DNA regions (trnL-F and trnG) was performed. The results suggest the evolutionary independence of B. mildeanum and B. alpinum, and the separation of both from B. gemmiparum, a species generally placed in the same subsection (Section Bryum, subsection Alpiniformia) as the other two.
