This study aimed to recognize the floristic composition, the life form and the distribution
of species of climbing plants occurring on 2 rock outcrops in the state of Pernambuco.
Monthly botanical collections were made from February to September 2015 at Pedra do
Cruzeiro (08°09′02.9″ S, 035°45′22.3″ W), municipality of Bezerros and Pico do Papagaio
(07°49′25.7″ S, 038°03′14.8″ W), municipality of Triunfo. Fertile specimens were collected
following the standard methodology in taxonomy. A total of 58 species were identified
from the 2 areas, all widely distributed in Brazil and belonging to 20 botanical families.
Apocynaceae, Convolvulaceae, Bignoniaceae, Dioscoreaceae and Fabaceae comprise 60%
of all species. The predominant life form was phanerophyte (62%). As for the growth
form, 67% of the climbers are herbaceous vines. The adaptation of twining was observed
in 69% of species. Six new records for the state of Pernambuco were also identified.
The rock outcrops studied show high species richness in relation to the found for
climbers in other rock outcrops in the Brazilian Northeast Region.
