lycopods. Species common in these upland savannas
are Pitcairnia angustifolia (Sw.) Aiton (Bromeliaceae),
which grows commonly around sulphur springs,
Charianthus nodosus (Desr.) Triana, Tibouchina
ornata (Sw.) Baill. (Melastomataceae), Viola stipularis
Sw. (Violaceae), Palhinaea torta (Sieber ex Underw. &
F.E.Lloyd) Christenh. (Fig. 6A), Lycopodium clavatum
L., Histiopteris incisa (Thunb.) J.Sm., Diplopterygium
bancroftii (Hook.) A.R.Sm. and the dominant Blechnum
ryanii (Kaulf.) Hieron. Locally, the rare Blechnum
rufum (Spreng.) C.Chr. and Pseudolycopodiella
meridionalis (Underw. & F.E.Lloyd) Holub can also be
encountered.
Other vegetation types that may include some fern
species are riparian forests, meadows and agricultural
land (pastures, fields and plantations) and
urban areas (walls and gardens). Many vegetation
types are more or less influenced by human activity
and severely altered vegetation can be found throughout
the archipelago. This often results in a dramatic
decrease in biodiversity as a result of deforestation.
In rare cases, the diversity of ferns has, however,
increased because of the availability of new habitats
and naturalization of ornamental species. Along roads
and in towns, for instance, ferns have found new
habitats in which to grow. Species like Anemia
adiantifolia (L.) Sw., Pleopeltis polypodioides (L.)
E.G.Andrews & Windham, Phlebodium pseudoaureum
(Cav.) Lell., Psilotum nudum (L.) P.Beauv.,
Cyclosorus dentatus (Forrsk.) Ching, Macrothelypteris
torresiana (Gaudich.) Ching and a few species of
Nephrolepis Schott have made old masonry, pavements,
roadsides and even concrete structures their
new home.
LIST OF SPECIES
In this checklist, genera are placed in their families
following the classification of Smith et al. (2006),
with the exception of Hemidictyum marginatum (L.)
C.Presl which is placed in Aspleniaceae following
phylogenetic studies by Schuettpelz & Pryer (2007),
and Lonchitis L. (see note there) that is here
treated as a separate family. The generic classification
of Hymenophyllaceae follows that of Ebihara
et al. (2006). Within families the species are sorted
alphabetically.
This checklist is primarily based on collections in
BM, GUAD, IJ, K, P, RB and TUR and on personal
observations in the field. Records from previously
published floristic studies (Fée, 1866; Husnot, 1870;
Duss, 1903; Questel, 1951; Proctor, 1977; Vivant,
1987a, b, 1988, 1989a, b, 1990, 1996; Fournet & Hoff,
1999; Lazare et al., 1991) have been evaluated and
included when appropriate. All species are accompanied
by their basionyms and types. Synonyms are
INDEX PTERIDOPHYTORUM GUADALUPENSIUM 221
only provided when a name was listed for Guadeloupe
in previous references. Types have been assessed and
are provided for all basionyms and for other names
that have a type specimen from Guadeloupe. Additionally,
habitat information, distribution within
Guadeloupe and a selection of studied specimens is
given. Naturalized species are in square brackets.
