Evolutionary botanist

Main questions and projects

  •  Taxonomy & phylogeny of diverse studied plant models (see below)
  •  Anatomy and morphology evolution in ferns
  •  Diversity and history of epiphytism (with focus on ferns, especially Hymenophyllaceae ; projects on orchids in progress)
  •  Diversity and history of flora of oceanic islands (with focus on Mascarenes and lesser Antilles)

Plant models (as the project leader (*) or as a collaborative contributor)

Main results

  • Taxonomy and classification of Hymenophyllaceae.

    The last global revision of the family has been published in 2006 (6) as a result of an international collaborative work I have initiated in 1993.

    Many publications clarifying the main relationships within the family or focusing on some local taxa, especially in Mascarene archipelago (1, 3, 4, 5, 7, 11, 17, 21, 24, 25, 28). Revision in progress on Comorian, Malagasy, Seychellois and African species.
  • Taxonomy and classification of African angraecoid orchids.

    Genus Bolusiella (18), new Rhipidoglossum species (19).
  • Taxonomy, classification and history of Mascarene Dombeyoideae.

    From the T. Le Péchon’s thesis I have supervised and further related works (9, 12, 13, 20).
  • Taxonomy and classification of Brazilian Eriocaulaceae.

    From the L. Echternacht’s thesis I have co-supervised and further related works (15, 23, 26).
  • Evolution of epiphytism in ferns and especially in Hymenophyllaceae.

    A review on the subject (10) ; and by evidencing relationships between morphology and anatomy regression and colonial epiphytism (2, 14, 22).
  • Origin and evolution of the megaphylly in Euphyllophytes and a focus on the fern megafrond.

    From the A. Corvez’ thesis I have co-supervised (16).
