Abrodictyum inexpectatum Dubuisson & Bauret & Boucheron-Dubuisson & Rouhan 2022, sp. nov.
No full textAbrodictyum inexpectatum Dubuisson & Rouhan, sp. nov., Fig. 3. Plants similar to Abrodictyum franceae Bauret & Dubuisson, but smaller on average and with fronds plane in the wild (vs. usually crispate or curled for A. franceae) and genetically different; also first supposedly close to A. angustimarginatum (Bonap.) J.P. Roux, but genetically different and displaying ultimate segments with more than three rows of cells on both sides of the terminal veins (vs. not more than three rows of cells for A. angustimarginatum). It also differs from A. dregei (Bosch) Dubuisson & Rouhan in mature fronds smaller in average, usually not exceeding 13.5 cm long (reaching 37 cm for A. dregei), lamina light green and translucent (vs. dark green and opaque), and sori obconic or cup-shaped (vs. cylindrical to slightly campanulate). Type:— MADAGASCAR. Antsiranana: Andapa, Parc national de Marojejy, abords du camp 4 et le long de la rivière, 14°26’43”S, 49°44’31”E, 25 September 2015, G . Rouhan, L. Bauret, & D. Ravelonarivo s.n. (holotype: P [P02434058]!) Epiphytic at the base of trunks or saxicolous ferns. Rhizomes short, erect, 0.5–1.0 cm in diameter, bearing long tufted, erect, red-brown and more or less catenate pluricellular hairs, densely covering apex, and numerous robust roots. Fronds clustered, semi-erect; stipes 1–3 cm long, wingless and slightly canaliculate on the adaxial surface bearing numerous scattered hairs identical to those of rhizomes; rachises, with wings on their upper part only, and main costae with hairs similar to those on the stipes and rhizomes. Laminae 5.5–10.5 × 1.5–3.5 cm, narrowly lanceolate with truncate base and acute apex, bipinnate-pinnatifid, light green and translucent, plane in the wild; pinnae 0.5–2.5 × 0.2–1.8 cm, lanceolate or ovate to narrowly oblong, sub-horizontal to oblique, basally sub-opposite then alternate; pinnules pinnatifid, lanceolate or ovate to linear, with lamina slightly decurrent along the second order costules; ultimate or terminal segments 0.2–0.4 mm wide (> 3 cells on both sides of the veins), linear and uni-veined with mostly acute (less often rounded) ends, sometimes fused by pair, the veins not reaching the margin; venation pinnate and anadromous; laminar cells thick-walled with walls up to 10 µm thick and more or less wavy, very variable in shape, mostly longitudinally oriented and sometimes oblique, tetragonal to pentagonal, less often hexagonal, isodiametric or longer than wide, especially in fused segments parts. Sori paratactic, mostly on acroscopic basal-most segments of proximal pinnules, 1.0–1.4 × 0.5–0.9 mm, usually 1 per pinnule, up to 6 per pinna, free with usually a thin full longitudinal wing on both margins or less often at the base, obconic (cup-shaped), truncate or with a slightly dilated mouth; receptacle short to long-exerted. Distribution and habitat: —Endemic to Madagascar, in the understory of rainforests, at middle to high elevations (550–1,600 m), according to the examined specimens. The species seems to be restricted to the north-east of the island in the province of Antsiranana, but the low number of specimens attributed to this new taxon does not allow a precise definition of its distribution and abundance. Indeed, the species is either rare or has been under-collected because it has been confused with more abundant species, such as A. franceae or A. dregei. New surveys in the province and elsewhere on the island in the lowland and montane humid forests are therefore necessary. Etymology: —The specific epithet is related to the unexpected nature of the discovery of this new species, only revealed by the molecularly sequenced specimen collected and first incorrectly identified as A. angustimarginatum. Specimens examined (paratypes): — MADAGASCAR. Antsiranana: Partie occidentale du Massif de Marojejy de la vallée de l’Ambatoharanana au bassin supérieur de l’Antsahaberoka, 15-25 November 1959, H .

Abrodictyum dregei Dubuisson & Rouhan 2021, comb. nov.
No full textAbrodictyum dregei (Bosch) Dubuisson & Rouhan, comb. nov., Fig. 2. Trichomanes dregei Bosch (1858: 372). Type citation: Hab. Cap. bon spei! Drège; Port Natal! Gueinbius. Type:— SOUTH AFRICA. Transkei, Lusikisiki, without date, J.F. Drège s.n. (lectotype S, S-P-18091!, 4 top specimens of the sheet only, here designated; isolectotypes BM, K, K000435631!, K000435632!). Remaining syntype:— SOUTH AFRICA. Port Natal, without date, W. Gueinzius s.n. (S, S-P-18090! 4 bottom specimens of the sheet only). Note:—The specimen B20 0106572 (B) may be eligible as an isolectotype following Roux (2009), but this specimen has not been retrieved. Roux (2009) also suspected the ‘holotype’ to be present at P, but we did not succeed in finding it, hence we designate here the S specimen as lectotype, in accordance with the note of Schelpe on the sheet (Fig. 2). In addition, the S specimen is better preserved than the K duplicates. The collector of the remaining syntype, cited as “Gueinbius” by van den Bosch, is likely a misspelling for Wilhelm Gueinzius, as correctly written on the herbarium sheet (Fig. 2); Wilhelm Gueinzius is known as a German naturalist who indeed collected in South Africa and precisely in Natal around 1841. = Trichomanes rigidum Sw. var. lugubre Christ (1901: 849).

Polyphlebium borbonicum (Bosch) Ebihara & Dubuisson

Short description Epiphytic or lithophytic; long-creeping filiform rhizomes, bearing sparsely distributed roots and reddish brown trichomes, and widely separated pending fronds; fronds stipitate, up to 17 cm long, more often less than 10 cm long, deltoid to ovate, pinnate-pinnatifid to bipinnate-pinnatifid, without false veins or folds; sori numerous, paratactic, twice or more longer than wide, cylindrical with slightly dilated mouth. Global distribution Tropical Africa and the western Indian Ocean, or pantropical (see note). Distribution in Comoros Anjouan, Grande Comore. Additional specimens examined COMOROS: ANJOUAN, Sommet du Tringi, 12 Nov. 2009, M.Pignal et al. 3725 (P02439799). GRANDE COMORE, La Convalescence (versant ouest du Massif), 24 Nov. 2002, F.Rakotondrainibe et al. 6793 (P00312024); Versant ouest du volcan Karthala, bois proche de Convalescence, 24 Oct. 2008, M. Pignal et al. 3383 (P02439786). Note This species, firstly considered restricted to tropical Africa and the western Indian Ocean, would be included into a large complex associating species from the Pacific and Neotropics (Ebihara et al. 2009). The species can be confused by its growth-form and gross frond shape and division with Crepidomanes bipunctatum and C. inopinatum. Both Crepidomanes species are rootless contrary to P. borbonicum but some Polyphlebium specimens can appear rootless if roots are not well developed. The sorus features are nevertheless more diagnostic. Sorus lips are clearly triangular in C. bipunctatum and not in P. borbonicum, and sori of P. borbonicum are twice or more longer than wide while sori of C. inopinatum are more or less as long as wide, always significantly less than twice longer (see Fig. 2C).Published as part of Ahamada H.

Jean Dubuisson : l’abstraction constructive
No full textInternational audienceAbstract : Architecte prolifique et exigeant, Jean Dubuisson est l'un des symboles forts des Trente Glorieuses. Auteur d'un nombre impressionnant de réalisations, il a su imposer au logement de masse un style et une qualité d'usage très largement reconnus, que son cadet Claude Parent décrit en ces termes : « L'architecture de Jean Dubuisson ? Avant tout l'amour de l'horizontale. Une horizontale rigoureuse, absolue, sans remise en question possible. Le culte de la pureté de la ligne. À la limite du graphisme, de l'épure. » Concepteur d'opérations qui ont marqué l'histoire de la construction et de l'habitat (le SHAPE Village à Saint-Germain-en-Laye, la résidence du Parc à Croix, Maine-Montparnasse, la ZUP de Chambéry), Jean Dubuisson, à qui l'on doit également le musée des Arts et Traditions populaires à Paris, a développé une esthétique proche de l'art abstrait et une subtile dialectique entre le dedans et le dehors. Cet ouvrage est la première monographie qui lui est consacrée
