Abstract

SIQUEIRA, Claudia R  and  WINDISCH, Paulo G. Pteridophytes of the North-western region of the State of São Paulo, Brazil: Dennstaedtiaceae. Acta Bot. Bras. [online]. 1998, vol.12, n.3, suppl.1, pp.357-365. ISSN 0102-3306.  http://dx.doi.org/10.1590/S0102-33061998000400004.

This work is part of a series of studies on pteridophytes of the North-western region of the State of São Paulo. The representatives of the family Dennstaedtiaceae are found mainly at the margins of the ciliary forests as well as in humid and shaded ravines, except for Pteridium which, generally occurs in open and sunny places. The genera Dennstaedtia with two species (D. cicutaria (Sw.) Moore and D. globulifera (Poir.) Hieroni), Lindsaea with three species (L. lancea (L.) Bedd., L. quadrangular is Raddi and L. stricta (Sw.) Dryand.), and Pteridium with a species and variety (P aquilinum (L.) Kuhn var. arachnoideum (Kaulf.) Brade), have been found in this region. Descriptions, illustrations, identification keys, geographical distribution, and habitats of each species are presented.

Keywords : Dennstaedtiaceae; pteridophytes; floristics; São Paulo; Brazil.
