Abstract

Five new species of Rublaceae f rom Brazil, Psychotria isanae Kirkb., Palicourea veterinariorum Kirkb., Pera ma carajensis Kirkb . , Borre ria reflexa Kirkb . and Sipaneopsis cururuensis Kirkb . . tive new species of Rublaceae from Colombia, Rudgea bracteata Kirkb . , Psychotria gonzalagunioides Kirkb . , Palicourea denslowiae Kirkb., Palicourea thermydri Kirkb . and Gonzalagunia congesta Kirkb., and one new variety of Rubiaceae from Colombia, Gonzalagunia discolor Standl. var. danielis Kirkb . , are described . One new combination is made, Psychotria cotejensls (Standl. ) Kirkb ., and one new name established, Psychotria aviculoides Kirkb . This is the first in a series of reports on new taxa of Neotropieal Rubiaeeae. The novelties included here were discovered in m:~terial sent for determination from NY and WIS or seen during visits to GOL, F, IAN and MG during the last three years.Rudgea bracteata Kirkbride, sp. nov.

Monograph of tribe Sipaneeae (Rubiaceae, Ixoroideae). A Neotropical group with its center of diversity on the Guiana Shield

“…In agreement with Kirkbride's (1980) discussion, Sipaneopsis cururuensis J.H.Kirkbr. is similar to S. rupicola (K.…”

Flora das cangas da Serra dos Carajás, Pará, Brasil: história, área de estudos e metodologia

“…As well as world scale iron deposits, the site includes manganese, nickel, lateritic and sulphide nickel, copper-gold and others, highlighting the region of Serra dos Carajás as one of the largest mineral provinces of the world (Freitas 1986;Santos 1986). Between 1960 and1980, the region received intense migratory flow made easier by the construction of the Belém-Brasília Highway (BR-222) that passes Marabá. Population growth was also driven by the building of the Tucuruí hydroelectric plant (around 260 km from Marabá), by the discovery of gold in Serra Pelada and by the implantation of the Ferro Carajás project, later absorbed by the daring Programa Grande Carajás (Silva 2006).…”
