Abstract:
The Serra da Arara, , localized at Alto Sertão Paraibano, micro region of Cajazeiras, it
is hosts a biodiversity never before investigated, although, intense human actions are
threatening the permanence of life forms in this environment. Before this scenario, It was
evidenced the predominance of representatives of the family Rubiaceae (fourth largest among
the Angiosperms), corroborating thus, with scattering centers of its species, as described for the
tropical regions. Therefore, in function of the absence of floristics information in the Serra da
Arara, this work was developed, objectifying to conduct the study of Rubiaceae occurring in
the area, thus contributing to the regional flora knowledge. From random collections, made
between February /2015 to July /2016, It was produced photographic records, descriptions and
an analytical key to species identification, indication of the geographical distribution and
comments from táxons. The collected material was produced following the techniques of
herborization contained in the specialized literature and deposited in Herbário JPB. The
Analysis of morphological characters It was made in the Botany Laboratory, at Universidade
Federal de Campina Grande, where the necessary equipment are available. Hitherto the
moment, the family Rubiaceae It is incorporated in Serra da Arara, for 11 species and 7 generas,
it being Borreria G. Mey., the most representative with three species [Borreria brownii (Rusby)
Standl.; Borreria capitata (Ruiz & Pav.) DC. And Borreria scabiosoides Cham. & Schltdl.],
Richardia L. and Tocoyena Aubl., with two [Richardia grandiflora (Cham. & Schltdl.) Steud;
Richardia sp.; Tocoyena formosa (Cham. & Schltdl.) K. Schum. and Tocoyena sellowiana
(Cham. & Schltdl.) K. Schum.], the others generas, Diodella, Oldenlandia, Spermacoce and
Staelia, it has only one representative [Diodella apiculata (Willd. ex Roem. & Schult.)
Delprete; Oldenlandia tenuis K. Schum.; Spermacoce tenuior L. and Staelia virgata (Link ex
Roem. & Schult.) K. Schum.]. Are featured Borreria brownii, being new reference to the Sertão
Paraibano, Spermacoce tenuior, possible new record for Brazil and Richardia sp., a likely new
species to science. Consequently, the data obtained can be to support the expansion of future
studies Rubiaceaethe, working the environment diversity of family, in addition to subsidise the
development of programs and initiatives that search for preservation, conservation and
maintenance of biological variety in the area.
