My passion for bryology started on quite an unusual path.

I was born in a small village in the east of France. As a child, I was already very close to nature; I enjoyed observing the little ferns and mosses on the old walls along the river.

After my high school final exam, I worked in the medical field, as a technician in a cytogenetic laboratory. There I began to enjoy using a microscope to observe cells and chromosomes for hours.

I have lived in the French West Indies for about 40 years.. I continued my career as a bio technologist in cytogenetics in Martinique and then in Guadeloupe: first in cytogenetics, then in molecular biology, for the screening of sickle cell disease and thalassemia.

However, at the weekend, I often went with my husband to explore the rainforest trails and began to look at bryophytes with increasing interest at each outing, feeling attracted by their somewhat mysterious aspect.

I had little literature available concerning the bryoflora of these islands, except for the cryptogamic flora of Reverend Father Duss (1901) and a bryological flora of Guadeloupe elaborated by a student in 1970. Then, as I was able to have access to the flora of the mosses of Mexico (ref) and to get a small microscope, I started a herbarium of bryophytes.

I was discouraged more than once, not being accustomed to using the bryophyte keys. Yet over the years, thanks to tenacity, and passion, I held on. And in 2009, I was contacted by the environmental department of Guadeloupe and the National Forestry Office of Guadeloupe and Martinique to assess the bryophyte flora of Guadeloupe and Martinique. It was a great opportunity to improve my knowledge of bryophytes. Numerous field trips, as well as data collected in the literature have led in 2011, with the collaboration of Mr. Alfons Schäfer Verwimp to the publication of a checklist of bryophytes of these islands.

Fortunately, I could retire early enough, which enabled me to indulge in my bryological research, as a member of the Guadeloupe Botanical Conservatory, by exploring many sites in Guadeloupe and Martinique during various studies:

From then on, I continued to search in the existing literature, to obtain other flora and publications, and spend time using the microscope. I was discouraged more than once, not being used to using the keys.

Several authorities of Guadeloupe and Martinique (the Regional Directorate for the Environment, Planning and Housing, the National Forestry Office, the National Park of Guadeloupe) trusted me and solicited me in the context of various studies:

In Guadeloupe

– Study on the status of the bryophyte flora of the French West Indies Guadeloupe and Martinique

– Study of the bryophyte flora of the managed biological reserveof Nord Grande-Terre (National Forestry Office)

– – Study of bryophytes as indicators of climate change, bryophytes collected along an altitudinal gradient on the Soufrière volcano, (MOVECLIM project) http://moveclim.blogspot.com/

– – Study of the bryophyte flora as part of a floristic and faunistic impact study on a water intake development site.

– Inventories of bryophytes during ZNIEFF programs (Natural Areas of Ecological, Faunistic and Floristic Interest)

In Martinique

All these studies have strengthened my passion for these plants, their esthetic expression, under the microscope as well as in the field, always producing a constant source of astonishment and wonder!

They allowed me to visit the New York Botanical Garden several times (2009, 2010 et 2013) to work on the bryophyte collections of the French West Indies of RP Duss. There, I met Bill Buck and Barbara Thiers who kindly helped me with the identification of some of my samples. When I went to the National Museum of Natural History, in Paris, I met Professor Jacques Bardat and Professor Robbert Gradstein who encouraged me to carry on with my research. Since then, we have established a friendly relationship and I appreciate his being available whenever I need help with determinations.

Bryology also allowed me to meet my friend Catherine Reeb (MNHN). We are working a lot together on the Marchantiophytes of the French West Indies and we “tracked down” the Riccardia and Riccia of Guadeloupe during her stays on the island. Thanks to her I could join the Madbryo working group and participate, in a workshop in Madagascar, in 2018. It was a great opportunity to meet eminent bryologists, to explore some beautiful Malagasy forests and I was proud to bring my contribution in bryology for the training of young Malagasy students.

Living in Guadeloupe is an advantage because the island is relatively small (1700 km2) and includes a large floristic diversity due to the bioclimatic gradients that extend from sea level to the top “La Soufrière” volcano (1467 m). This aspect is extremely interesting from an ecological point of view! How fortunate, indeed, to to be able to observe bryophytes in very dry environments one day and in the cloud forest the day after, only a few miles from my home!
