Study about genus Tillandsia (Bromeliaceae). (In Spanish and Catalan)

By “Joan Carles Freixanet

I’ m performing a study (in Spanish and Catalan) about the adaptation of genus Tillandsia (Bromeliaceae) in the zone of Valles (A region near Barcelona – Spain). I have got a collection which I’m extending with new acquisitions and interchanges. I pick up climate data to see which species are more adapted to the mentioned zone. I began to start this study 6 years ago. If you find it interesting, I could interchange information and experience with other people who might be interested in it. I could offer the result and conclusions in the future. Any information about this genus will be very well received.
