Slézec A.-M., Aymonin G., Aupic C., Comtet-Andriamanjatoarivo S. & Grouard J.-C. 2010. —Une collection de référence: l'herbier de Jean-Henri Fabre. Adansonia, sér. 3, 32 (1): 7-29.

Jean-Henri Fabre's (1823–1915) house in Sérignan-du-Comtat (Vaucluse, France) is the property of the Muséum national d'Histoire naturelle, Paris since 1922. From 2000, this place is the subject of a partial renovation of the buildings and a complete saveguarding of the collections of the scientist, including a little known herbarium. The phanerogams of the French flora are well represented, specifically the ones from Vaucluse, Corsica and Hautes-Alpes. The cryptogams collection (algae, lichens, mosses and fungi) completes and increases the scientific interest of the whole. The SONNERAT database now allows the systematic ordering, consulting and mining of the data regarding the 10 010 phanerogams samples. This herbarium in which four isosyntypes have been discovered, to which 103 fungi reference specimens should be added, is now part of the French national collection but is still housed in the l'Harmas in Sérignan.

Rakotondrainibe F. 2010. — Deux espèces nouvelles de Pseudotectaria Tardieu sect.Pseudotectaria (Pteridophyta, Tectariaceae) de Madagascar et discussion sur les sectionsPseudotectaria et Isopinnatae Holttum. Adansonia, sér. 3, 32 (1): 31-38.

Two new species of Pseudotectaria Tardieu sect. Pseudotectaria (Pteridophyta, Tectariaceae) from Madagascar and discussion on the sections Pseudotectaria et Isopinnatae Holttum.

Two new species of Pseudotectaria Tardieu sect. Pseudotectaria, P. analamazaotrensis Rakotondr. and P. jouyana Rakotondr., are described and illustrated. Their affinities with the two others species in the same section, P. crinigera (C.Chr.) Tardieu and P. decaryana (C.Chr.) Tardieu, are examined and summarized in a new identification key. Pseudotectaria analamazaotrensis differs by the pinnae being simple and petiolulate, the proximal pinnae being as long as the next ones with the acroscopic side as wide as the basiscopic one. The proximal pinnae of P. jouyana are pinnatiseque; veins from the acroscopic side of pinnae anastomosing and those from basiscopic side often free. Criteria differentiating Pseudotectaria and Isopinnatae Holttum sections are updated taking into account the two new species morphology.

Deroin T. 2010. — Floral anatomy of Magnolia decidua (Q.Y.Zheng) V.S.Kumar (Magnoliaceae): recognition of a partial pentamery. Adansonia, sér. 3, 32 (1): 39-55.

Floral anatomy of the endemic Chinese species Magnolia decidua (Q.Y.Zheng) V.S.Kumar was studied in order to clarify its disputed relations within the family Magnoliaceae. Its most striking feature is a change in floral merosity, clearly demonstrated by the vasculature, the three perianth whorls being often pentamerous, while only the gynoecium might be considered as trimerous. Interestingly the androecium exhibits an intermediate condition, as the stamens are supplied by 15 vascular trunks, a pattern reminiscent of that previously described in Meiocarpidium Engl. & Diels (Annonaceae), with two levels of 15 trunks each. Perianth pentamery, almost completely lacking sclerenchyma at anthesis, as well as a sharp separation in the vascular supply of the perianth and sexual parts, characterize unmistakably this species from all other known Magnoliaceae, even though its relationship with Magnolia sect. Manglietia is otherwise strengthened by stamen and carpel pattern. This very unexpected pentamery — somewhat comparable to that of the monocot genus Pentastemona Steen. — is briefly discussed. The value of vascular anatomy as an additional but essential source of data to complement the standard phyllotactic and ontogenetic approaches used for the flower, is emphasized again.

Kurzweil H. 2010. — A precursory study of the Calanthe group (Orchidaceae) in Thailand.Adansonia, sér. 3, 32 (1): 57-107.

A review of the Thai species of the Calanthe group (Orchidaceae) is presented, based on the examination of over 500 herbarium and spirit specimens, and is a precursor for a later treatment in the Flora of Thailand. The group comprises the genera Calanthe R.Br., Phaius Lour, and Cephalantheropsis Guillaumin. In the genus Calanthe, 21 species are recognized, one of them being new but incompletely known as only a single flower was available for study. Calanthe angustifolia (Blume) Lindl. is newly reported for Thailand. Unusual forms of C. vestita Wall, ex Lindl. are commented on, and the extensive variation in the spur length of C. triplicata (Willemet) Ames is discussed. Five Phaius and one Cephalantheropsis species are recognized. Identification keys to the three genera and all species are given, and descriptions are provided for all species. A selection is illustrated by line drawings.

Baldini R. M. 2010. — Panicum maculatum Aubl.: its type and the correct use of Lasiacis maculata (Aubl.) Urb. (Poaceae, Paniceae). Adansonia, sér. 3, 32 (1): 109-119.

The type of Panicum maculatum Aubl. is confirmed here in order to establish the correct application of Lasiacis maculata (Aubl.) Urb. The interpretation of the Plumier's plate on which Panicum maculatum Aubl. is based confirms that this species cannot be referred to Lasiacis ligulata Hitchc. & Chase as reported either by old or recent literature, but to Lasiacis sorghoidea (Desv. in Ham.) Hitch. & Chase (=P. sorghoideum Desv. in Ham.). A nomenclatural synopsis for L. maculata (Aubl.) Urb. is also provided so as to clarify its nomenclatural framework.

Bourguignon V. 2010. — Sedum aetnense Tineo ex Guss. (Crassulaceae), a new species record for the flora of Greece. Adansonia, sér. 3, 32 (1): 121-123.

The presence of Sedum aetnense Tineo ex Guss. is newly reported in Greece. It was collected East of the Prespa lakes, close to the border with Albania and the Former Yugoslav Republic of Macedonia.

Durbin O., Chesselet P. & Labat J.-N. 2010. — Richesse de l'herbier de Paris en types d'Astragalus asiatiques et lectotypification d'Astragalus superbus Bunge (Fabaceae).Adansonia, sér. 3, 32 (1): 125-133.

The richness of the Paris herbarium in Asian Astragalus types and lectotypification of Astragalus superbus Bunge.

In the context of the Global Plants Initiative digitization project of nomenclatural types and associated data, 864 type specimens of Asian and Middle-Eastern Astragalus L. (Fabaceae) species were discovered in the Paris herbarium collections (P). Emphasis is laid on the Bunge collection from which a significant number of Astragalus type specimens originate, as well as on the Paris herbarium's richness in type specimens. Finally, a lectotype is designated for Astragalus superbus Bunge based on material used in this study.

Danet F. 2010. — Rhododendron heterolepis (Ericaceae), une espèce nouvelle de Papouasie.Adansonia, sér. 3, 32 (1): 135-139.

Rhododendron heterolepis (Ericaceae), a new species from Papua.

A new species, Rhododendron heterolepis Danet, recently discovered in the Indonesian province of Papua is described and illustrated. It differs from other species in the section Vireya (Blume) H.F.Copel by having an heterogenous and unequally distributed indumentum of scales on the underside of the foliar limb. It can be separated from R. scabridibracteum Sleumer by having a pink corolla, smaller and less indumented bracts, pauciflorous umbels, smaller anthers, an ovary with scales clearly visible between simple hairs, and a glabrous style in the upper half.

Jongkind C. C. H. 2010. — Jasminum cuneatum Jongkind (Oleaceae), a new species from Guinée, Liberia and Côte d'Ivoire. Adansonia, sér. 3, 32 (1): 141-143.

The new species Jasminum cuneatum Jongkind (Oleaceae) from western Africa is described here. It differs from J. paucinervium Benth., a species that occurs in the same area and that is the most easily confused, by its cuneate and not rounded or cordate leaf base and the absence of pit domatia. It differs from J. kwangense Liben from Central Africa by the more papery leaves without abundant glandular dots and pit domatia on their lower surface.
